Hi All,
Just wondering what the best/most accepted way to measure tank level off pressure transmitter. Pressure transmitter is located in line with the outlet (0m).
4-20mA PT also has Zero and Span buttons.
My 2 methods i can see:

My 2 methods i can see:
- Take PT out of tank and press Zero. Return to tank and fill to overflow, press Span.
- Take PT out of tank and press Zero. Using Druck pressure pump calibrator, pressurize PT to known value above tank overflow eg: 5m, and then calculate Zero-100% (4.3m) in code.
Cheers,
