Technical InformationTI234F/00/en
Application• The Prolevel FMB 662 measures level
in liquids using one or two hydrostaticprobes. The transmitter, designed formounting in the field, determines thelevel in two vented tanks, calculatesvolume and monitors limit levels.Differential level measurement is alsopossible.
• Special functions with two probes onone tank: level measurement in onepressurised tank or densitymeasurement of a liquid, levelmeasurement in one vented tank withautomatic compensation for variationsin density.
• System integration via the Rackbus RS-485 interface.
Features and Benefits• Economical transmitter for field
mounting with IP 66 protection• Simple start-up, simple operating
matrix, can be configured byEndress+Hauser operating anddisplay programs
• Reliable operation: function monitoringof probe and transmitter.

Measuring System
Measuring System• Prolevel FMB 662 and • two Deltapilot hydrostatic pressure
sensors with electronic insert EB 17 Zor EB 27 Z
Hazardous Areas Provided it they are used with a certifiedtransmitter (in preparation) the certifiedsensors can be mounted in thehazardous area.
Differential Functions• Differential measurement between two
levels• Hydrostatic level measurement in a
closed tank:A positive or negative gauge pressurewill occur in a closed tank if there is nopressure compensation withatmospheric pressure. The pressureacting above the water column isalways measured at the bottom of thetank. This requires a Deltapilot to beconnected to the second channelinput which measures only the gaugepressure pe in the tank. The Prolevelsubtracts the gauge pressure from thepressure of the first channel and thuscompensates for the effects of gaugepressure.
• Other functions: density measurementof a liquid or automatic compensationfor variations in density.
Analogue OutputsThe Prolevel transmitter provides astandard 0 to 20 mA signal per channel(switchable to 4 to 20 mA). Dependingupon calibration, this is proportional toeither level or volume. The start and endof the signal range can be programmedas required.
Relay OutputsThe Prolevel is equipped with fiverelays, each with a potential-freechangeover contact. • two sets of two limit relays with
adjustable switch point and hysteresis
Additional System Components ForRackbus RS-485 Interface OptionHardware• RS-485 interface card or RS-232C/
RS-485 converter for connection to apersonal computer

System Integration
Personal ComputerTransmitters equipped with a RackbusRS-485 interface can be connected to apersonal computer via the RackbusRS-485 bus. A measuring system thencomprises:
• Several Prolevel measuring points (or other units with Rackbus RS-485interface)
• PC connection (RS-485 interface cardor a RS-232C/RS-485 converter).
Depending on the system topology, upto 25 transmitters can be connected atvarious points on the bus, which may beup to 1200 m long.
Process Control Systems The Prolevel FMB can be easily andeconomically integrated into existingindustrial process control systems.Individual Rackbus RS-485 buses, eachwith up to 25 transmitters, areconnected to the Rackbus via the FXA 675 interface card (exceptionallyvia Monorack RS-485). A gatewayconnects the Rackbus to standardsupervisory systems such asPROFIBUS, FIP or MODBUS.

Operating Principle Hydrostatic Pressure MeasurementHydrostatic pressure is created by theweight of a column of liquid. When thedensity ρ is constant, the pressureacting on the sensor is simply a functionof the height h of the column.
Signal ProcessingThe Prolevel provides the sensors withpower over an unscreened two-wirecable. Every sensor supplies aninterference-free, level proportional,pulse frequency modulated (PFM)signal via the same cable. Themeasured value derived from this signalis displayed at the transmitter andoutput as a standard 0/4…20 mA signal.It may also be read by a Commulog VU 260 Z handheld terminal or passedon to a supervisory system via theoptional Rackbus RS-485 interface.
Function MonitoringThe Prolevel transmitter monitors thecomplete measuring system from thesensor to the outputs. On fault condition:
• the alarm relay de-energises and thecorresponding LED lights
• the current falls to –10 %, rises to+110 % or holds the last value(programmable)
• the limit relays respond according tothe fail-safe mode selected orde-energise (programmable).
Simple Linearisation A linearisation is made by entering avessel characteristic which describesthe relationship between the height hand volume V of the vessel.
The most common application – ahorizontal cylinder – is pre-programmedin the transmitter. A linearisation tablefor any other vessel shape, e.g., a tankwith a conical outlet, can be simplyprogrammed by entering up to 30reference points.
Density MeasurementIf both Deltapilot sensors are coveredand the difference in height betweenthem is known, then the density of theliquid can be calculated from theformula:
The density can be measured in bothclosed and vented vessels. A density-compensated levelmeasurement is only possible in anopen vessel.
p hydrostatic = ρ ⋅ g ⋅ h
ρ = densityg = acceleration due to gravityh = distance between the surface of the
liquid and the centre of the sensordiaphragm

Hazardous AreasWhen laying cables in hazardous areas,the maximum permissible values for U,I, R, L, C (see Certificate of Conformity)and all local regulations are to beobserved.
Electrical IsolationCurrent output, relay outputs, powersupply, sensor input and bus inputs areelectrically isolated from each other(safe isolation to DIN/VDE 0160).Both sensor inputs are intrinsically safeand electrically isolated from each other.
Overvoltage ProtectionThe external overvoltage protection unitHAW 262 for signal outputs isrecommended for protecting thetransmitter from voltage peaks,especially when it is mounted in thefield. The overvoltage protection unitHAW 261 should be used to protectagainst mains power voltage peaks.
Electromagnetic CompatibilityThe interference immunity of theProlevel has been checked to a teststrength of 10 V/m. The signal deviationover the total frequency range of 10 kHzto 1 GHz is always less than 1 %. Overwide frequency ranges the deviation issignificantly lower.
Bus Installation Rackbus RS-485Normally, up to 25 Prolevel transmitterscan be connected to the bus: the actualnumber depends upon the topologyand conditions of operation. The busconnection requires:
• connecting cable (two-core, twistedand screened)
• cable length: max. 1200 m.
Bus AddressEvery transmitter is given a uniqueaddress which is configured at the DIPswitches at the terminal strip.
Termination For reliable transmission of thecommunication signal:
• set the terminal resistance at the PCboard and the furthest Prolevel fromthe board to 150 Ω.
The bus power is provided by the PCinterface card or RS-232C/RS-485adapter.

Operation Simple OperationThe six keys on the front panel are usedto configure the instrument or call upmeasured values: parameters are displayed on the 4-digit LC-display.
The transmitter is configured via anoperating matrix, whereby each field isselected by the (vertical) and
(horizontal) keys. Parameters areentered using only three keys ,
,
: pressing the key stores and registers the entered value.
Operating MatrixWhether the Prolevel is configured viathe keypad, with the handheld terminalor remotely via the Rackbus RS-485interface, the easy-to-use operatingmatrix ensures programmingprocedures are uniform and clear. Anin-depth knowledge of Endress+Hauseris not needed instrumentation to quickly configure the transmitter.
Handheld TerminalAll Prolevel transmitters can beoperated by the Commulog VU 260 Zhandheld terminal, which displaysparameters, measured values andoperating status. Its large display givessimple, self-explanatory information onall parameters in the language selectedwhen ordering. The transmittercontinues to measure normally whiledata are entered or read.
