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...

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 =...
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...
