Technology Solutions TEK-DP...of the primary element and reading three DPs, TekValSys DPro analyses not just the traditional single DP reading, but the entire axial pressure field

2 [email protected] | www.tek-trol.com

The Tek-DP 1620A Differential Pressure (DP) Cone meter is ISO 5167-5 compliant. A member of the DP type meter family the cone meter has an inlet pressure port and a low pressure port located in the downstream face of the cone. The flowrate is calculated from known geometry, known fluid properties, and the measured DP via the ISO DP meter flowrate algorithm.

The cone meter is proven to be remarkably resistant to inlet flow disturbances, and is applicable to many gas, steam and liquid applications whether long or short inlet runs, where low costs, low maintenance, and high metering accuracy is required.

The Tek-DP 1620 DP Cone Meter is available in a wide range of standard and exotic materials in a size range of 2” thru 48” sizes.

Introduction

The Tek-DP 1620A Cone Flow Meter operates according to ISO 5167-5, i.e. the conservation of mass and energy induces a differential pressure (ΔP) across the cone element which is proportional to the flowrate (Q). The flowrate (Q) and DP (√ΔP) have a parabolic relationship such that Q α √ΔP. A DP transmitter reads the ΔP.The cone meter beta (β) describes the cone diameter (d) relative to the inlet diameter (D), where β = (1-(d/D)2). The cone beta is chosen for a given application, and this beta dictates the corresponding ΔP range for that application’s flow conditions.

Measuring Principle

The relation between the differential pressure and the flow rate is represented as the following expression:

The Flow Rate is proportional to the square root of the differential pressure. Where, ΔP is Differential Pressure. Q is Flow Rate.

The Tek-DP 1620A Cone Flow Meter mainly comprises of 3 elements i.e., meter body or tube, a cone assembly, and a pair of pressure taps.

A cone meter is a Differential Pressure (DP) meter with a cone primary element. The reduction in flow area caused by flow past the cone causes a readable DP which is proportional to the flowrate. The DP is read by a digital DP transmitter, and the flow calculated by software carrying out the ISO 5167-5 algorithms on a flow computer or SCADA system. The cone meter is rugged, reliable, economical, has a wide flow range, and is very resistant to disturbed inlet flow.

The beta is a measure of the size of the cone diameter (dc) relative to the meter body diameter (D), and is calculated by:

Manifolds:

Transmitters:

Valve manifolds isolate the transmitter from the process lines. Manifolds allow easy access to the DP transmitter for recalibration, maintenance, or replacement without having to interfere with process lines and / or close in the flow.

The Tek-DP 1620A Cone Meter monitors the thermodynamic condition by utilizing pressure and temperature transmitters. The meter reads the ΔP across the cone element via one or more DP transmitter/s. Alternatively a multi-variable DP trannsmitter may be used to read the pressure, temperature and ΔP. For wider flow range / turndowns multiple DP transmitters of different ranges can be ‘stacked’.


Benefits

Optional Tek-DP 1620A Cone Meter Verification System:

• Suitable for 2” to 48” with flanges rating from #150 to #2500 as per ASME. • Simple, Robust & Reliable• Extremely immune to flow disturbances • Eliminates straight runs requirements• Minimize metering footprint and reduce weight• Maximum installation flexibility• Low Cost and Minimal Maintenance• Suitable for difficult or severe applications• Accuracy up to ±0.5% of flowrate• High Repeatability• Full optional verification system ‘Prognosis TM’ available

Applications

• Gas, Liquid and Steam flow• Custody Transfer Measurement• Well Head Measurement• Fuel Metering• Wet Gas Flow• High and Low Viscosity Liquids

The Tek-DP 1620A Cone Meter has an optional verification system, powered by the DP meter diagnostic suite ‘Prognosis TM’. With an optional 3rd pressure tap downstream of the cone element three DP transmitters can read the primary, recovered, and permanent pressure loss DPs. This allows the application of the ‘Prognosis TM’ axial pressure profile analysis diagnostic system.

This diagnostic suite runs in the TekValSys Flow Computer FCA, monitors the meter in real time, and facilitates Condition Based Maintenance (‘CBM’). The results are displayed in a user friendly plot, clearly indicating if the meter is fully operational or has a problem. Pattern recognition techniques allows the source of a problem to be identified.

TekValSys:The Tek-DP 1620A Cone Meter uses the TekValSys Flow Computer FCA as the meter head. The FCA operates the ISO 5167-5 cone meter calculation routine, and has fluid property equations of state available, including the AGA 8 fluid property calculations. The FCA monitors flowrate in real time and can be used in custody or non-custody transfer applications.

TekValSys DPro is unique, powerful, industrially-proven, and real time validation and monitoring system for Differential Pressure Flow Meters. Figure 8 shows the Tek-DP 1620A Cone Flow Meter with TekValSys DPro System.The Field Mount Flow Computer is offered with the optional TekValSys DPro comprehensive verification system for Differential Pressure (DP) meters. This expands the DP meter capability by offering a powerful diagnostic suite allowing for condition-based maintenance (CBM) operations. The diagnostic results are displayed in a simple and easily understood format.TekValSys DPro is a comprehensive DP meter verification system. Utilizing a third pressure port downstream of the primary element and reading three DPs, TekValSys DPro analyses not just the traditional single DP reading, but the entire axial pressure field. This expands the DP meter capability, offering a full diagnostic suite. TekValSys DPro creates a smart DP meter facilitating condition based maintenance (CBM) operations. TekValSys DPro creates seven diagnostic checks, i.e. one DP integrity check, three separate inter-comparable flowrate predictions, and three DP ratios comparable with baselines. The HMI (human machine interface) is designed for simplicity: the seven diagnostics are plotted as four points on a graph with a 1x1 box. All points inside the box shows the meter is functioning normally (see Fig 9). Any points outside the box shows a potential metering issue. Figures 10 and 11 show response to varying saturated steam quality and single-phase DP reading error, respectively. Pattern recognition technology allows the source of the problem to be directly identified.

TekValSys DPro can detect many varied Cone Meter problems such as: Incorrect Inlet or Cone Diameter Keypad Entry, Incorrect Calibration Data In Use, Two-Phase Flow, Debris Trapped at the Cone, Contamination Build-Up, Damaged Cone Assembly, Plugged Impulse Lines, Saturated or Drifting DP Transmitter, Incorrectly Spanned DP Transmitter, Leaking Manifold Valve, DP Below DP Transmitter Range etc.

DP Diagnostics can be added to a new install cone meter where the TekValSys DPro diagnostic baseline is set during the meters standard discharge coefficient calibration. For existing in-service 3rd party cone meters TekValSys DPro can be retrofitted if the meter has a downstream pressure tap and the user uses the as found diagnostic performance as the diagnostic system fingerprint.

FLOW

• Installation for Upstream and DownstreamIn most of the flow elements, the proper operation and performance depend on unrestricted upstream and downstream piping length requirements. The fully developed symmetrical flow profile is achieved with relatively short upstream and downstream lengths. Therefore, it needs minimal upstream and downstream straight pipe runs. The Cone meter can be installed with 0 to 5D and 0 to 3D downstream.
