There are two methods: 1. workshop calibration, 2. field
Calibration.
Suppose you installed transmitter at vessel and want to
calibrate it.Follow following field procedure:
1. Close process side valves of both upper and lower
flanges.
2. Lose upper remote seal from process flange, It should
not get any pressure from process.
3. Remove lower side transmittrer flange from process side
flange. (It will be high side of transmitter)
4. Put your local made calibration flange at transmitter
remote seal and apply pressure.
(This flange must be same level of vessel flange from where
you removed it)
Suppose transmitter range is 0 to 1000 mm of H2O.
5. Apply this supply to your connected flange and take
readings at 0, 250, 500, 750, 1000 mm of H2O.
