Hydrostatic pressure produced by the water column at the bottom of the controlled liquid reservoir uses the trapped air in the measurement tube to produce the same amount of pressure on the sensor. At ...

A common way of measuring the level of liquid in a tank places a low-pressure sensor at the bottom. The pressure readout is the product of the liquid column height times the density of the liquid. As ...

Liquid-level sensing based on capacitive sensors comes with its own challenges. It’s like absolute capacitance sensing. Unlike touch detection, the absolute value of the liquid level needs to be ...

A pressure transmitter can be used to establish the liquid level in a river, tank, well, or other body of liquid. The pressure at the bottom of a liquid filled container is directly connected to the ...

Recently I came across some non-contact liquid level sensors and gathered them out of curiosity. They have been available in the market for the past few years, but this time I was lucky enough to get ...

Miniature ultrasonic liquid level switches detect liquid levels in space-constrained applications, such as fluid storage tanks, compressors, boiler tanks, hydraulic reservoirs and chillers.
