Warning Indicates a procedure that has to be followed strictly as contravention could result in escaping gas, and cause property damage, serious injury or death

Caution Highlights a procedure which, if not strictly followed, can result in damage to the meter

Note Is an important element of the procedure and should be observed

2 Introduction The Dresser Meters & Instruments Turbine Meter is a velocity type of meter which, by means of a turbine wheel mounted on a main shaft and a counting mechanism, measures a known volume of gas with each rotation. As a result of years of development and experience, we have been able to pro-vide a meter of high accuracy and reliability. The construction of the meter and the materials used will give years of faithful service even under very demanding conditions. The special designed coupling guarantees fl exibility in functionality for the future, since indexes and electronic switches can be replaced on-site with the meter in-line.

!

It is therefore prudent to consult the specifi c technical data sheets and other documents which accompany the meter. If in any doubt, GE should be consulted.

2.1. International reference material

The Turbine meters are designed in accordance with the following international standards. Not all of them are applicable for the Q series

OIML R6 : General specifi cations for Gas Volume Meters

OIML R32: Rotary Piston Meters and Turbine Gas Meters

EN 12261: Turbine Gas Meters

MID MI-002: European Gas Meter Directive

EEC: Gas meters

3 General description

STOP

STOPThe meter must be considered a part of the pressure containing system.

3.1. Operating principle

The operating principle is based on the measurement of the gas velocity. The fl owing gas is accelerated and condi-tioned by the meter upstream straightening section. This straightening section conditions the gas fl ow by removing undesired swirl, turbulence and fl ow profi le asymmetry be-fore it impinges on the turbine rotor. The dynamic forces of the fl uid cause the turbine rotor to rotate. The turbine rotor is mounted on an axial shaft with high precision low friction stainless steel ball bearings.

The turbine rotor has helical blades. The turbine rotor angu-lar velocity is proportional with the gas velocity. The rotat-ing movement of the turbine rotor and its primary gear train, all fi tted in a pressurized body, drive a 100% sealed external gear box taken care for the error adjustment. An exchangeable eight digit mechanical counter is fi tted on op of the gear box. Normally LF pulse transmitters are fi tted in to the meter counter.

We have developed a series of turbine gas meters up to 100 bar. All meters are based on the concept of a Remov-able Meter Cartridge (RMC). This enables the owner/opera-tor to change the characteristics of the meter on-site. For all 2” to 8” cast and bare stock meter body four types of RMC’s are available, for welded bodies 3 cartridges are available, to offer maximum modular fl exibility in terms of minimum capacity, maximum capacity, pressure loss, etc.

3.2. Cartridge

Since the cartridge can be pre-calibrated by certifi ed test institutes, upgrades in performance or functionality can be done easily and locally. Re-calibration of meters becomes a matter of hours, since the cartridges can be exchanged on site, reducing logistical efforts to a minimum and still keeping the quality and performance at the highest level. The weight of the Removable Meter Cartridge is signifi cant-ly lower than a complete meter, meaning that rapid and careful transportation of the cartridge can be done without complex and time consuming shipping arrangements.

The meter cartridge as well as the turbine wheel is machined from high quality aluminium to guarantee long term stability. The cartridge is coated (anodized) to overcome wear and corrosion of the fl ow channels caused by dirt and dust.

By using a special ring to position the cartridge in the meter body, the cross-sectional area of the cartridge is signifi cantly larger compared to conventional turbine me-ters. This enables to manufacture meters with an extended maximum capacity. Where, with most of the conventional

3.3. Transport

To overcome damages of the main bearings caused by shock loads, it is recommended to transport turbine meters with trucks having a dedicated air suspension. The aluminium bodies are in terms of strength equivalent to the iron GGG40 meter bodies and are certifi ed to be suitable for all classes up to ANSI 150 or DIN PN 16. Aluminium from its nature has better material properties than iron and steel cast at lower temperature ranges and will not become brittle, for instance like the GGG40 will. The hard anodized coating will give the meter body a superior protection against corrosion.

When during transportation the meters are subjected to shock loads due to bad road conditions, the fi rst damage of the bearings will already occur without notice. The shock load in combination with the weight of the turbine wheel will cause impacts between the tiny balls and the inner/outer ring of the ball bearing. This is the start of an excessive wear resulting in increased friction. Eventually the bearings will collapse. The use of low weight plastic turbine wheels is not considered seriously since the performance is poor and the impurities in the gas will degrade the plastic wheel and as such will signifi cantly affect the accuracy of the meter. To reduce the forces acting on the main bearings, the main bearing (larger than the secondary bearing) is positioned exactly in the vertical centre line of the turbine wheel, meaning that the resulting forces on the tiny secondary bearing are eliminated.

meter manufacturers e.g. a 6” is available as high as 1600 m3/h, the 6” can easily handle a capacity of 2500 m3/h. Being able to apply one size smaller turbine meter will not only have a positive effect on the purchase price of the meter but will allow to use smaller piping, regulators, etc. and will reduce the size of the station and its building signifi cantly.

All the critical components, including the turbine rotor and primary gears, are housed in the ReMovable Cartridge (RMC), making the concept very suitable for local production and assembly. Except for the RMC the remaining parts like meter body, external gear box, index, etc. can be manufactured locally according to local directives and quality standards. Since the RMC is the actual measuring mechanism, and not depending on the meter body, the quality of the locally produced and assembled meter will meet the highest requirements.

3.4. Load compensation

The initial certifi cation of the meter is carried out with atmospheric air with a density of about 1,2 kg/m3. To be able to achieve a rangeability of at least 1:20 the bearings must be very small in order to reduce the mechanical friction. As the forces on the turbine wheel and as such the axial load on the bearings are proportional to the density of the gas measured, the axial load on the bearings is signifi cantly higher when the meter is operated at higher pressures (at 8 bar natural gas conditions the density is already 5 time higher which also applies to the axial load on the main bearing). Consequently the bearings will be overloaded when running at high capacities unless construction-al provisions have been made. The Turbines are compensated for this density related additional axial load. The Axial Load Com-pensation (ALC) will compensate for the density related axial load on the turbine wheel by causing a slightly over pressure down stream the turbine wheel. This overpressure will push the wheel back against the direction of the gas fl ow and as such restricting the axial load acting on the main bearing. Unfortunately this ALC will make the meter much more sensitive to dirty gas, since dirt tends to accumulate in the area where the pressure is increased (near main bearing). To solve both problems the bearings, gears and shafts are located upstream the turbine wheel, meaning that the ALC works well without affecting the condition of the bearings with dirt and or dust.

3.5. Conditions of bearings

In order to keep the bearings in proper condition it is essential to flush out the dirt (dust) and refresh the oil on a regular basis. Turbine meters equipped with so called “lubricated for life” are not recommended – except for vertical installation – since dust in the gas will slowly accumulate and degrade the performance of the bearing and as such the accuracy of the meter. As stated by the German law, meters without lubrication must be re-calibrated at least once per 8 years (with lubrication once per 12 years). Even with the relatively clean gas as used in Germany, this limitation has shown to make sense. As a consequence of the global energy trade, the expand-ing infrastructure of the global pipeline network (with sup-plies from remote areas) the quality of the gas is changing rapidly. For applications were the gas is not absolutely clean, conventional oil system injecting oil in the bearings by means of an oil pump, are not sufficient . This principle takes care only for the refreshment of the oil but will not flush the dirt/dust out of the bearings. For more severe conditions the bearings have to be flushed too. Oil systems that not only refresh the oil but also flush the bearings and wet the rotating parts (gears and shafts) are widely used in all types of applications (cars, compressors, etc.) and in rotary meters. The turbine meters are equipped with a refreshing and flushing system whereby the oil is pumped into a reservoir in the bearing block (where all the bear-ings, shafts and gears are housed). A splash vane running at high speed (speed of the main shaft) distributes the oil through the bearing block, flushing, cleaning and wetting all the parts and surfaces. Test with similar oil systems like implemented on rotary meters show a significant improve-ment of the life time.

To improve the resistance against dirty gas even further, turbine meters have the bearings mounted deep inside the bearing block only accessible by a labyrinth. This means that it is basically impossible for dirt particles to get into the bearings.

On special request the meter can be supplied with prelubricated bearings for those applications where maintenance is awkward, the loads are low and the gas is clean.

3.6. Index

The mechanical index is 100% sealed to prevent con-densation and accumulation of moisture. The index is equipped with a slot for an electronic pulse box to allow maximum flexibility. By changing the pulse box, the meter can be fitted on-site with several types of Low Frequency pick-ups. Mechanical index with smart encoder is also available giving the advantage of more reliable results, flow direction recognition, tamper switch, digital pulse outputs and much more.

3.7. Operating condition

The turbine meter is suitable for handling most types of clean, dry, common gases at either constant or varying flow rates. The meter is not suitable for handling liquids. Measurement accuracy and life expectancy can be impeded by excessive deposits of dirt of other types of foreign material present in the gas stream.

Meters of standard construction are not directly suitable for handling oxygen, acetylene, and biogas or sewage gas. Specially constructed meters made of materials directly

compatible with these and other gases are available. Please contact GE for details.

The turbine meter has a Maximum Allowable Operating Pressure (MAOP) rating. (Refer to the basic meter body type-plate for the MAOP.)

Every meter is leak tested at 1.1 times its MAOP and the strength is tested at 1.5 times its MAOP, all in accordance with International Standards and Codes. Important: The maximum working pressure of a turbine meter is limited by casing design. Meters should not be installed where line pressure can exceed the Maximum Allowable Operating Pressure.

STOPTemperature range according “Rules for Pressure Vessels” is determined by body material and is important regarding safety. The operating temperature range, according Rules for Pressure Vessels, is stated on the body type plate of each meter.

The standard MID-approved metrological operating temperature range is -25°C to +55°C.

The measured volume measurement is independent of the gas specific gravity, temperature and pressure. The measured volume can be easily converted to volume at Standard conditions for elevated pressure and varying temperature by application of the Basic or Ideal Gas Laws.

In some countries it is not allowed to change the index without supervision by the local met-rological authorities. Removing the seal could invalidate the metrological status of the meter.

Meter Indexes

Using a special coupling, the index of the meter can be changed on-site with the meter in-line. This enables to change the functionality in the future by just “one click”. The Index is already prepared for the most commonly used functions. For information regarding availability contact GE or your Dresser Meters & Instruments representative.

In some countries it is not allowed to change the pulse box without supervision by the local metrological authorities. Removing the seal could invalidate the metrological status of the meter.

Electronic pulse box

Using a removable/external pulse box, the electronic output of the meter can be changed on-site with the meter in-line. This enables to change the functionality of the electronic output in the future. The pulse box is already prepared for the most commonly used functions. For infor-mation regarding availability contact GE or your Dresser Meters & Instruments representative.

As there are many options for the electronic pulse box, details about the functionality and the connectors are indicated on a separate document supplied with the meter.

Accessories

Various accessories such as volume correctors, pressure and temperature transmitters, etc. can be fitted to the turbine meter. When connecting these accessories, reference should be made to the instructions and other documents accompanying these products.

The turbine meter is equipped with a thermo well for mounting a temperature sensor or a temperature transmitter (max. 6 mm).

4 Receiving handling and storageTurbine Meters are precision measurement instruments. Although of very rugged construction, reasonable care should be given during handling and storage.

At time of delivery:

1. Check the packing list to account for all items received.

2. Inspect each item for damage.

3. Record any visible damage or shortages on the delivery record.

■ Claim a file with the carrier

■ Inform GE or your Dresser Meters & Instruments representative immediately

■ Do not accept any shipment with evidence of mishan-dling in transit without making an immediate inspection for damage and checking each meter for free rotation of the turbine wheel. All new meters should be checked for free rotation after arrival since damage to internal work-ing parts can exist without obvious external evidence.

■ Should any serious problems be encountered during installation or initial operation of the meter, notify aDresser Meters & Instruments representative immediately.

■ Do not attempt repairs or adjustments, as doing so is a basis for voiding all claims for warranty.

■ If the meter is not tested or installed soon after receipt, store in a dry location. Leave the protective caps or tape installed at the meter flanges. The caps or tape will provide reasonable protection against atmospheric moisture.

■ Do not add oil to the meter until after the meter has been installed in a permanent installation and is ready for service. Not applicable in the absence of a pump.

■ When reporting a suspected problem, please provide the following information:

- Your sales order number and/or GE order number.

Authorization for return is required for all Dresser Meters & Instruments Products shipped to the Factory for repair, calibration, warranty, exchange or credit. To obtain autho-rization for return of GE products purchased from a Dresser Meters & Instruments Distributor of Representative, please contact the Distributor or Representative from whom the product was purchased.

5 Meter installationInstallation only by authorized skilled people.

International, national, local and company safety rules are to be strictly followed as contravention may result in serious injury or death.

STOP

The gas should be clean and free of liquids, dust or foreign material, which could damage or block the turbine wheel.

Piping Confi gurations

5.1. Position

Environmental conditions applicable to the Meter: Mechanical class M2 & Electromagnetic class E1.

Ambient temperature range from -25°C to +55°C Meter can be placed in open air. Avoid direct sunlight on the meter.

IP-clasification of Index: IP65 ( No condensation possible)

Preferable, the turbine meter is installed horizontally. A vertical installation is not recommended since the load on the bearings is increasing due to the load of the turbine wheel. In case the meter must be installed vertically some internal parts will be specially machined to drain conden-sate and oil.

Do not install the meter lower than the discharge pipe run to avoid accumulation of condensate and foreign material in the metering chamber. Use a Gasket Strainer or other Y-type strainer upstream of the meter to remove liquids and foreign matter (pipe sealant, tape, weld slag, etc.) from the gas stream. A 160 micron mesh screen is recommended. All upstream piping should be cleaned before installation.

Do not install a lubricated gas valve (plug type) directly up-stream the meter, as excess valve lubricant or other foreign material can damage or block the turbine wheel.

If over-speed conditions occur, a restricting flow orifice plate should be installed 2 to 4 pipe diameters downstream of the meter outlet. Contact GE for sizing, pricing and avail-ability. Warranty does not cover over-speed conditions.

5.2. Inlet

The minimum straight inlet section upstream the turbine meter must be at least 2 times the diameter of the turbine meter according to the EN12261 directive for turbine me-ters. To limit any error deviations due to the perturbations, it is recommended to use a straight inlet section of 5 times the diameter of the meter. The use of a 5 times D inlet sec-tion will also keep the possibility open for a future change to an other type of meter, like for instance an ultrasonic meter.

Alternatively, arrangements recommended for turbine meters may be used allowing for more compact installa-tions. Tube bundle flow straighteners as described in ISO and AGA standards are also suitable to eliminate swirl. Perforated plates are recommended when pressure regula-tors are close coupled to the meter. In case perforated plates are used the pressure loss over these plates can be recovered by connecting the sensing line of the regulator downstream this plate.

The downstream piping may be of any configuration pro-viding the diameter of the connected pipe work is equiva-lent to the nominal bore of the meter. Reducers (one size reduction), elbows, tees and full bore valves can be fitted directly to the meter.

5.3. Placing in line

Remove the plastic protective caps or tape from both meter fl anges prior to meter installation.

!

1. Before installing a meter make sure the upstream piping is clean by partially opening the valve to let a suffi cient amount of gas blow to atmosphere.

2. Insure the turbine wheel turns freely and no objects or contaminants are in the measuring chamber. Perform a spin test. At the end of a spin, the wheel should stop smoothly, not abruptly.

3. Meter Orientation: connect meter inlet to the gas supply side of the line, insuring the gas fl ow will be in the same direction as the arrow on the meter body nameplate. Turn the index in the required position.

4. For aluminium meter bodies only: tighten fl ange bolts evenly in a cross-pattern. The fl ange bolt thread engagement should be at least 1,5xD into the meter with a a maximum torque of:

M16 (5/8 UNC): 130 Nm

M20 (3/4 UNC): 180 Nm

5. Connect connectors to the index according to the diagrams accompanying the meter.

If the meter is installed in a zone classifi ed as hazardous area, then ensure all connections are to intrinsic safe circuits.

STOP

5.4. Startup

Do not exceed 5 psig/second (35 kPa/second) maximum when pressurizing. Rapid pressuriza-tion can cause an over-speed condition which may damage the meter. Resulting damage is not covered by warranty.

!

Slowly pressurize the meter in accordance with the following recommendations.

1. Open the bypass and outlet (downstream of meter) gas valves.

2. Partially open the meter inlet gas valve until the meter starts operating at low speed. Throttling of the bypass valve may be necessary to initiate gas fl ow trough the meter. Verify gas is fl owing through the meter by watching for movement of the index drum. If move-ment is present, go to step c). If the index drum is not turning, verify gas is being delivered to the meter. If gas is fl owing to the meter inlet and meter is not moving, go to step e).

3. Let the meter operate at low speed for several minutes. Listen closely for unusual scraping or knocking sounds.

4. If operation is satisfactory, go directly to step 6.

5. If unusual sounds are present or the meter is not turning, stop the installation procedure. Slowly depressurize and vent all pressure from the meter set before checking for piping misalignment, piping strain, torsion, or other related problems. Once the problem has been resolved, repeat the start-up procedure beginning with step a).

6. Gradually open the inlet valve until full line fl ow is passing trough the meter and the inlet valve is fully open.

7. Slowly close the bypass valve.

8. Follow your company authorized procedure or common practice to test the meter and all connections for leakage. Soapy water and gas analysers are commonly used for this procedure.

6 Maintenance

It is not allowed to carry out any repair or maintenance when the meter is pressurized or in operation.

STOP

A turbine gas meter can be used for measure-ments of gases with extremely high and low temperatures. Avoid direct contacts with the meter in operation since touching the meter can cause serious injuries.

STOP

It is not allowed to carry out any inspections when the meter and the adjacent piping is pressurized.

Periodic Inspections

STOP

Like all precision instruments a Dresser Meters & Instruments turbine meter is vulnerable to abuse and operating conditions beyond its specifi cations and limits.

!

It is prudent therefore to periodically check the security and running conditions of the meter. Especially, when a signifi cant over pressure or shock load has occurred, or the installation is subjected to abnormal vibrations or if the gas is excessively contaminated.

!

Removing metrological seals may invalidate the calibration.

Meters installed and maintained in accordance with GE recommendations can be expected to operate dependably for many years. Proper maintenance according to the recommended lubrication schedule and cleanliness has the greatest effect on meter life expectancy. If the meter is supplied with a pump the oil reservoir of the oil pump must be clean and not polluted with dirt and moisture.


9

6.1. Oil

Use only Aeroshell Fluid 12 Oil or equivalent instrument grade oils approved for service by GE.

The lubrication frequency will depend upon the cleanliness of the gas being measured. It is recommended to lubricate the meter once per three month taken into account the following restrictions:

- Do not lubricate when due to seasonable effects the meter is running for a longer period at lower capacities (like summer time).

- Do lubricate more often due to seasonable effects the meter is running for a longer period at fl ow close to the maximum capacity (like winter time).

- Do not lubricate when the meter is running below 25% of the maximum capacity, since the oil vane inside the meter will be less effective.

Two types of pumps are available:

1. A small push bottom pump used for small meters and/or low pressure

2. A large lever handle pump used for large size meters and/or high pressure

6.2. Push bottom

Traditional oil pumps collect dirt and moisture. This dirt and moisture together with the oil injected into the bearings will cause major errors and eventually will damage the bearings. To avoid dirt and moisture accumulation, the oil pump can be rotated in respect to the meter and as such avoiding dirt or moisture entering the oil reservoir. The sequence of fi lling up the reservoir is shown in the fi gure below:

1. When not activated, the position must be with the reservoir pointing downwards.

2. Remove the reservoir for fi lling with fresh oil (rotate the reservoir counter clock wise). Make sure the reservoir is clean and free of moisture before fi lling. Read the correct lubricant volume to apply each period from table below. Fill the reservoir accordingly by reading the volume indictor scale.

3. Install the reservoir by rotating it clock wise.

4. Inject all the oil in the meter. The amount of oil is suffi cient to fl ush the dirt out of the bearings and to wet all the moving parts.

5. After all the oil is injected in the meter, the oil pump must be turned back to the initial position (pointing downwards)

Maintaining the oil procedure is crucial for long term proper functioning of the meter. Any dirt or moisture getting close to the main bearings can damage the bearings.

For a proper fl ushing of the main bearings and to wet all the rotating parts, the amount as shown on the reservoir is suffi -cient. Fill up the reservoir as shown on the label. Be sure that the reservoir is clean and free of moisture before refi lling or replace the reservoir with a new one. Larger reservoirs and replacements are available.

6.3. Lever handle pump

Oil pumps can collect dirt and moisture. To assure only clean and pure oil is injected into the bearings the oil pump can be purged and as such avoiding dirt or moisture entering the meter.

– Use only reommended oil

– After oiling turn reservoir downwards

Maximium oil level

1. A low and a high pressure version is available see Part number on the cap.

2. Make sure the reservoir is clean and free of moisture before lubricating the meter: remove the purge plug and allow dirty oil and water to drip from the reservoir, replace the plug.

3. Open cap by lifting (NOT BY ROTATING) and fi ll the reservoir with fresh prescribed oil.

4. Keep the cap open and fi rmly strike the handle, Watch the oil level is dropped.

5. Pump the requested amount of oil in the meter, see above table. The cap should be closed cautious.

The amount of oil is suffi cient to fl ush, clean and lubricate the bearings and other moving parts.

Purging

If the quality of the gas is very poor, it is recommended to install a purge system. By purging the bearing block with clean gas (fi ltered before entering the meter), an over pressure is maintained in the bearing block to prevent the dirty gas entering the bearings and bearing block. For more detailed information please contact GE directly or the Dresser Meters & Instruments representative.


11

In some countries it is not allowed to change the index without supervision by the local metrological authorities. Removing the seal could invalidate the metrological status of the meter.

To optimize the effect of cleaning it is recommended to remove the cartridge out of the meter and do the clean-ing with just the cartridge. Be aware that removal of the cartridge means that the metrological seals have to be broken. If local authorities allow removing the cartridge the cleaning procedure is as follows:

Cover all holes in the cartridge and inject dry and clean compressed air through the connection of the oil pump (this will create an overpressure in the bearing block, avoiding solvent for cleaning will enter the bearings and shafts). Windmill the turbine wheel (at a speed less than the maximum capacity) by injecting controlled compressed air from a nozzle into the cartridge inlet. During wind milling the preferred position of the cartridge is vertical with the fl ow direction downwards. Flush approximately 150 ml non-toxic, non–fl ammable solvent through the meter. Use compressed air to completely dry the meter. After re-install-ing the cartridge the meter must be lubricated extensively.

Cleaning and fl ushing

If there is any evidence of dirt or dust in the meter a suggested method for removal is to windmill the turbine wheel (at a speed less than the maximum capacity) by injecting controlled com-pressed air from a nozzle into the meter inlet. During wind mill-ing the preferred position of the meter is vertical with the fl ow direction downwards. Flush approximately 150 ml non-toxic, non–fl ammable solvent through the meter. Use compressed air to completely dry the meter. After cleaning and fl ushing the meter must be lubricated extensively.
