Answer / kuber

The pressure will be proportional to the flow rate, as the
flow rate increases the pressure at inlet of the valve will
increase. then the valve starts to close relatively.

Answer / r.murugan

if pressure transmitter installed before pcv (example sp
10bar) suddenly pipe line flow increase pressure will
increase but as long as controller an auto controller will
give command to open the valve to maintain the setpoint pressure

if flow rate is less pressure is coming down less than
setpoint controller will give command to close the valve to
maintain the pressure (if pressure tapping before control
valve)

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 ?
