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 ...

Liquid level sensor, also called fluid sensor or float switch, usually has two parts: a stem and a float. The stem is stationary and attaches to the top or bottom of a tank. One or more reed switches ...

Will not be affected by the type of liquid. Can detect the liquid level of boiling water Strong compatibility penetrates all kinds of non-metallic containers or pipes such as plastic, glass, ceramic, ...

Abstract: This paper addresses the nonlinear control design problem for a state coupled two-tank liquid level system. For this system's dynamics, motivated by a desire to provide precise and economic ...
