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 ...

Liquid-level switches used in aircraft, nuclear-power plants, medical equipment, and other critical applications must be precise and reliable. For that to happen, design engineers must know the ...

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 ...

ProSense VFL Series Vibration Fork Level Switches from AutomationDirect use tuning fork technology for reliable liquid point level detection for monitoring, alarming, and control applications. The ...

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 ...
