Liquid level Measurement - Viatran

Liquid Level Measurement 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.
