    P&T compensation for flow measurement

    Sorry I skipped explaining current set up. It is basic that for a orifice meter the vol flow rate (and not mass flow rate) is proportional to square root of DP/rho. Since Transmitters have the capability to perform the square root extraction, a signal of 4 to 20 is sent proportional to the...

    P&T compensation for flow measurement

    Hai I wish to compensate for the kg/hr flow indication sent by a dp (orifice) meter. I want to use the below formula F_comp = F_act * (((T_ref * P_act)/(T_act*P_ref))^0.5) F_ comp = compensated flow in kg/hr F_act = actual flow in kg/hr form transmitter T_ref = T_ref in degC + 273.15 P_ref =...

    Any Optimization Tool that is free in the net?

    Hai I want to perform P&T compensation for flow from an instrument signal. I wish to use below for the correction. F_comp = F_act* (((T_ref * P_act)/(T_act * P_ref))^1/2) Fcomp and F_act in kg/hr T_ref = Tref in degc+273.15 P_act - P_act in barg+1.013 What is the correct reference temperature...
