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 ...

The float, the flapper, or the fill valve are the most likely causes of a toilet running continuously. You can perform easy tests like monitoring water movement to help identify the cause. Whichever ...
