David,
I think that the formula is for compensating the diference in operating conditions respect the design T and P for orifice plate calculation. If so, then the compensated flow must be "standardized" with the formula that includes the compressibility factor.
Correcting the above information, the transmitter output is DP and the extraction is made in the DCS, then the flow is used in the formula.Seems were not considered the conversion from actual to standard conditions after correcting the flow which needs another calculation, is this correct?
Hi,
I´m going through a gas flow measurement loop and am a bit confused about the way it´s configured. The flow is measured with an orifice plate (Pd = 8 kg/cm2 man, Td= 37.8°C)and the associated transmitter outputs the flow in ft3/h; the actual pressure and temperature are measured with other...
