thanks for replying. Should I correct the air volume flow rate for the inlet pressure ratio? I mean, if the calib. law is Q [cfm] = (calib. coeff.) * Delta_h [mmH2O] should it be Q [cfm] = (calib. coeff.) * Delta_h [mmH2O]* P_upstream/P_atm ?

calb law is not at standard coditions ;-) I meant calibrated at certain conditions and then used at others.

Hi I have a question about measuring volume flow rate with a laminar flow element. I read the pressure difference across the element (mmH2o) and I get volume flow rate (cfm) from a calibration law. If that calibration law was obtained at standard conditions, would I have to correct it for...
