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 ...

Recently I came across some non-contact liquid level sensors and gathered them out of curiosity. They have been available in the market for the past few years, but this time I was lucky enough to get ...

In this article, we focus on the use of graphene in water sensors, exploring how these sensors detect common contaminants, including heavy metals, microbes and irregular pH. Various types of sensors ...

Panasonic Corporation has developed an ultrasonic gas flow and concentration sensor for hydrogen that enables the real-time simultaneous measurement of the flow rate and concentration of hydrogen ...

UrFU scientists together with Italian and Bulgarian colleagues synthesized new heterocyclic fluorophores — four types of carboxamides of 2-aryl-1,2,3-triazoles. Their photophysical properties were ...

In industrial oils, contamination of water can pose a number of problems in machinery parts. When water is present, the lubricant’s viscosity changes considerably and chemical changes also occur, all ...
