A special sensor can accommodate various device sizes while recording accurate notes regarding substance levels such as blood, insulin, and IV fluids. A non-contact level sensor does not come into ...

In this paper, a dual-parameter liquid level and refractive index (R.I.) sensor is fabricated using three pieces of bare polymer optical fibers (POFs), which can independently and simultaneously sense ...

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 ...
