There is a water injection line and flow is measured using differential pressure transmitter. The flow element is orifice plate. Flange taps for flow measurement is at an elevation of 500 mm from the deck level stancion mounted transmitter needs to be installed at an elevation of 1.5 Mt at the same deck level since there is no deck below for mounting of transmitter being a liquid service.
Also the piping isolation valve is a double block and bleed arrangements and is very close to the grating of the deck. The tapping orientation is at 45 deg angle based on liquid service. The impulse lines have mandatory got to be piping and not tubes. Hence flexibility in routing is reduced.
Can anybody advise on the transmitter installation for accurate measurement in spite of elevation discrepancy.
