11.1.4 Configurable Options
Configurable options include:

Gas analysis concentrations for up to 21 components
 Accumulator Rollover
 Reference temperature and pressure for both gases and liquids
 Orifice and pipe diameters, selection of type of taps, and tap locations, and
so on.
 Meter K Factor and Meter Factors with 5-point linearization curve
 Temperature, Pressure, and Density Correction for liquids
 Local Atmospheric (barometric) pressure
 Default process and operating parameters such as DP Threshold for flow
cutoff, and so on.
 Metric or US units
 User-selectable units for totalizers and flow rates on a per channel basis
 Resettable and non-resettable totalizers for every meter channel.
11.1.5 Supported Meters
The following meter types have been used with the PTQ-AFC module. Because
of the broad range of meters available in today’s market, refer to the meter’s
specifications and the contents of this manual to evaluate the use of the AFC
modules (even if the meter is listed here). If you have questions, please contact
ProSoft Technology Technical Support Group.
Meter Type Configured As (Differential or Linear)
Turbine Linear
Orifice Differential
V-Cone Differential. You must configure the meter as V-Cone type in the AFC Manager
(Meter Configuration / Calculation Options)
Wedge Differential. Refer to Wedge Meter Applications (page 225) for information
about using the wedge meters.
Vortex Linear or Differential
Ultrasonic Linear or Differential
Coriolis Linear or Differential
Note: For Vortex, Ultrasonic or Coriolis meters, the selection depends on the output generated by
the meter.
If the meter provides a pulse train representing the volume increment, the AFC meter should be
configured as Linear with Primary Input selected as Pulse Count.
If the meter provides the instantaneous flow rate, then the AFC meter should be configured as
Differential with Primary Input selected as Flow Rate.
Note: The module does not support applications to measure water, because the implemented
standards are applicable to hydrocarbon fluids only.
