We have a installation where we need to measure water level from 0 to 10 metres with a submersible pressure sensor, but we are going to have difficulty in getting some of the sensors vented to atmosphere pressure, are there any of these sensors that do not need to be vented to atmosphere?
We would suggest using a 2 bar absolute range IMSL submersible pressure sensor which would be non-vented. You will also need to measure the atmospheric pressure as well, and we would suggest a DMP 331 barometric range pressure sensor, which will provide the signal for subtracting from the absolute pressure reading of the submersible sensor to determine the level.
