Thermal and pressure compensation formula
Thread Content
Regarding the use of orifice plates for measuring standard gases, I would like to know what the compensation formula is; please advise.
As a fake expert, I really don’t want to tell you; go read books by yourself.
F=SQRT((P+1.01325*100)/(Pb+1.01325*100)*(Tb+237.15)/(T+273.15)) *Fi, where Fi represents the original flow rate. I’m not clear about what the original flow rate is – could you explain that?
As this so-called expert, let me say a few words: Fi refers to the flow rate measured by the transmitter. Whether to use this formula depends on the form of the transmitter signal – whether it is a differential pressure signal or a flow rate signal.
It is a differential pressure signal. How is this differential pressure signal converted into flow rate? Is it directly in the form of 4-20mA? :o
What is the relationship between Fi and the differential pressure measured on-site? I would appreciate your guidance on this.
