In 16' pipeline one pcv is installed which is controlled by
PT installed at inlet of PCV.If Flowrate in pipeline
increases what will happen to pressure at the inlet of pcv.

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)

Answer / triptisliet@gmail.com
according to bernauli's theorem total enerngy will remain
same so if velocity increases then pressure decreases.

Answer / tony lorenzo
If the controller is in Auto that time, and provided its been tuned, the pressure should remain as is. The PCV valve should open as expected, how much? we dont know.

Good Evening all.My question is - For a feed water line to an equipment if i need to measure the flow we will use orifice /magnetic/vortex depend on cost/spec.If i need to measure a ''Alarm''signal and ''Interlock'' from one point i think we can use orifice type in one location with 2 different tapping points - one for alarm and one for an interlock to flow valve..If in case i need to have both these signals(Alarm & interlock) from magnetic flow meter,is it possible??will 2 seperate sensors will be located inbuilt r we can program it ??..i thk we can have one transmitter with these 2 signals...need to know any technical issues are there?pls clarify
