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... Read More

On bottom of the circuit board for any MVI products, you' ll find three jumper banks: COM1, COM2, and Setup. Each jumper position is labeled 232, 422 and 485. Read More

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 ... Read More

You cannot download a new .AFC file while any of the meter runs are enabled, or illegal data values will be reported by AFC manager. First you must disable all meter runs. This can be done either using the AFC manager, or the easier way is through... Read More

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... Read More

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... Read More

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. Read More

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... Read More

If there is no analysis available, the user must supply in the meter configuration a suitable default relative density (= specific gravity), the density of the gas relative to air at the reference conditions. If there is an... Read More

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... Read More
