Do ProSoft AFC Flow Computers support annubar-type flow sensors?
No, the annubar is a different kind of differential pressure sensor; It is essentially a multiple pitot tube, which requires a different kind of calculation than an orifice plate....

ProSoft AFC flow computer modules implement the Bernoulli equation for measurement of fluid flow through concentric square-edged orifices. The Coefficient of Discharge in this equation is calculated by an appropriate Standard, which may, by option selection, be chosen as either A...

For Vortex, Ultrasonic or Coriolis meters, the selection depends on the output generated bythe meter. If the meter provides a pulse train representing the volume increment, the AFC meter should beconfigured as Linear with Primary Input selected as Pulse Count. If t...
Lire la suiteIs it possible to configure an AFC flow computer solutions to use the ISO 6976 computation standard?
The short answer is, "No, it cannot." The reason it cannot is this:ISO 6976 is the ISO standard for calculating compressibilities and energy content of natural gases. It is similar to the older (pre-1992) edition of AGA 8 (compressibilities) and the current ...
Lire la suiteFor what purposes would I use the Multiple Meter Streams options on my MVIxx-AFC Flow Computer?
The Multiple Meter Streams options can be used to more efficiently compute flows through a single meter at a physical site that has different fluids flowing through the meter at different times. Since each Stream will have it's own meter configurati...
Lire la suiteDo ProSoft AFC Flow Computer solutions support "ASME MFc-6M", "API-11" and/or "API-12" calculation standards for measuring lubricating oils?
The API-11 and API-12 calculations are available in ProSoft AFC Flow Computers, beginning with version 2.05. MPMS Ch 12 specifies, essentially, the necessary factors and calculational sequence for measuring liquids, and the general method of measurement using ...

The attached document describes the differences in the calculations when using AGA 3....

The AFC is not designed to receive a corrected flow input.However if the AFC is being used only for its accumulation and archive capabilities, then rather than the process temperature and pressure inputs, provide the meter's reference conditions as the AFC's temperature and press...
