PT installed at inlet of PCV.If Flowrate in pipeline
increases what will happen to pressure at the inlet of pcv.
Answer Posted / 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)
