They use a buoyant float to gauge a fluid level. In most models, the float carries permanent magnets and encircles a stationary stem. As the float rises or drops with fluid level, the magnetic field ...

A few months ago, I wrote about a very popular cable float switch for another site (https://www.codrey.com/electronics/cable-float-level-sensor-switch-first-look ...

Sometimes we need a non-contact liquid level sensor. There are several ways to build that, but the easiest is to try an optical liquid level sensor. You may already have an idea in mind since you are ...

Drive process engineers require more reliable and precise level measurement systems because of the needs of sophisticated automated processing systems, an increasingly stringent regulatory environment ...
