|A pressure differential gauge type of instrument has a
manifold with 2 isolation valves (hp and lp),2 vents(1 each
for hp and lp) and 1 equalizing valve. Determine the
position of each valve(either fully closed or fully open)
when troboulshooting to:
1. zero the transmitter.
2. determine if there is a block in the impulse line.
3. determine if the gauge is functioning properly.
The process fluid is water.

|a pressure transmitter with a range of 0 to 2500kpag has a specified accuracy of
0.5 % of span.It is to be calibrated using a comparison gauge to have an accuracy
of 0.1% of span.The comparison gauge has a range of 0 to 3000kpag
What is the accuracy ratio? is this ratio acceptable?
|Can we measure pressure using differential pressure
transmitter? If yes then how?
|what is relation between electronics&instrumentation
|What are the reliability data ,like failure rate etc,for

|what happens if we are having very very high cavity and
flashing in a control valve..??? is it stops
working...immediately... or eroded...slowly
