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 sensing based on capacitive sensors comes with its own challenges. It’s like absolute capacitance sensing. Unlike touch detection, the absolute value of the liquid level needs to be ...

Keurig Dr Pepper. has filed a patent for a beverage machine that can determine the liquid level in a tank without a dedicated sensor. The machine uses a controller to calculate the liquid level based ...
