If you’re the person tasked with controlling the level of fly ash in collection hoppers, you know how difficult the application can be. What at first looks like a simple measurement quickly proves to ...

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 ...

In Part 1 of this article, we explained popular liquid-level sensing methods and their limitations. We also delved into why capacitive-sensing techniques are superior to traditional methods used for ...
