A pressure transmitter can be used to determine the liquid level in a tank, well, river or other body of liquid. The pressure at the bottom of a liquid filled container is directly related to the height of the liquid.
The transmitter measures this hydrostatic head pressure and gives the resulting liquid level. To get an accurate reading, the measurement device needs to be located at the lowest point you want to measure; typically mounted or laying on the bottom of the container.
