what is the reason for flow fluctuations happen on
differential flow transmitter during in service
Answer Posted / seth
Change in process pressure, restriction in one of the
sensing lines, rapid change in temperature, noise in the
signal being returned to the source of indication. (Check
for noise in the shielding-blow down sensing lines-check if
the process media is at the correct operating temp.-make
sure the equalizer valve is closed and the sensing (hi and
lo) lines are open.
