The flow transmitter is installed before the control valve,reason being the transmitter reads the flow from orifice plate then from the output of flow transmitter to the final controller then to control valve.

flow transmitter range is 0 -500 mmwcc but the transmitter shows 12 ma for o mmwc instead of 4 ma ...how to solve this problem when we apply 375 mmwc it shows 16 ma

We do have a problem in the company that is one PT connected to PlC which is mean 1 out of 1 in PLC system we do have the PAHH is 55 mbar and PALL 8 mbar with a timer of 15 sec for the PAHH the problem started when PAHH goes more than the set point which is 55 it reached up to 71 but due to timer doesn't trip . We force it and we checked everything nothing there . We replaced the transmitter problem still there the reading goes more than the 55 bar the range for transmitte is 0- 60 mbar . So we did loop check , aculaizing valve , wiring all are okay . What the possible causes for this ???
