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 new sensor has been designed to replace mechanical float switches. The Leveltrak is an electronic non-floating sensor. It detects level without any moving parts. Using capacitative sensing ...

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 ...
