suppose there is gas flow meter I want to know weather
meter calibration is done at high pressure or low pressure?
pls justify.

Answer Posted / amit
Meter Caliberation Is Done at Low Pressure,Because At low
pressure range We get high Accuracy,High Resolution which
helps for Detection of Deviation Quickly and Can Be
Caliberated Quickly by Fine Tuning.

Calculate the maximum pressure drop that can be allowed to occur across a control valve, so that we can prevent cavitation / flashing from occurring. Use the following formula: Δ P allow = Km (P1 – PvapourA) where, Δ P allow - the maximum allowable differential pressure for sizing purposes, or terminal pressure drop; Km- the valve recovery coefficient from the manufacturer’s catalogue; P1 - absolute inlet fluid pressure; PvapourA - absolute fluid vapour pressure at the inlet temperature; Use Atmospheric pressure = 101.3 kPa, P1 = 1200 kPa(g), PvapourA = 4 kPa, KM = 0.72
