Flow range for orifice plate
We need to set up a pressure transmitter on an orifice plate for flow measurement. How can I calculate the flow range to set up the transmitter?.
Expert’s answer: Flow range for orifice plate
Usually when you set up a differential pressure transmitter, you need to decide what variable the device will measure, such as flow, level, volume, mass, and others. Then you can use the equations below to find your flow range for orifice plate.
Maximum flow: Max flow = K x √ΔPmax
Constant: K = max flow/√ΔPmax
Differential pressure: ΔP = (flow/K)²
Output (4-20 mA): Output mA = [(%ΔP) x 16 mA] + 4 mA

Lower and upper range values of differential pressure transmitter
On my differential pressure transmitter, I have a range from 0 to 500 psi. We use an orifice plate for creating differential pressure. Maximum DP in our gas flow is about 200 psi but it’s not fixed. Can you tell me how to determine the lower and upper range values?
