|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
b) what is the signal output of the transmitter when flow
rate is 2500 m3/Hr ?

|there is one orifice plate already installed on 3" line, but
my previous engineer(who is not working here) removed that
tx, but now i want to take it in to the process, so now what
i have to do now? flow fluid is hytherm oil of temp. 260deg
& pressure is 3bar.
