If a differential pressure transmitter is calibrated for 0~2500 mmH2o and transmits a 4~20mA dc signal. The transmitter is placed across an orifice plate which is sized to create 2500 mmH2o differential at 5000m3/Hr a) what is the flow rate when the transmitter signal is 13.0mA DC? b) what is the signal output of the transmitter when flow rate is 2500 m3/Hr ?
