Level measurement technologies | First Sensor

A pressure sensor can measure the hydrostatic pressure and the liquid level can be determined after calibration to the specific density of the process media. In vented tank or open container applications gage pressure sensors which measure relative to atmospheric pressure are used to avoid false results due to barometric pressure fluctuations.

Measuring Liquid Levels Using Pressure Transmitters

· The principle of pressure transmitters, when used to determine fluid levels, is as follows: the pressure at the bottom of a fluid body is proportional to the height of the fluid above it. This is the hydrostatic head pressure, and is measured by the transmitter to obtain the fluid level reading. For accuracy of measurement, …

Using absolute pressure sensors to measure hydrostatic level

When measuring the water level in a freshwater reservoir for example, the hydrostatic pressure sensor is measuring both the pressure of water above its position and the atmospheric air pressure acting on the surface of the reservoir. Normally a vented reference would be used to equalise the offset due to atmospheric pressure so that the true water level is measured. However if it is necessary ...
