Why Pressure Transmitter is NOT installed before up-stream of an ORIFICE PLATE? in a flow measurement.
Answer Posted / ashwani kumar
I had never came across this situation.
Orifice creates a pressure drop across the plate and hence measuring the pressure on the upstream doesn't provide any significance. Pressure after the orifice always carries significance.
