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 ...

For the liquid level detection of non-conductive liquids in the field of biochemical analysis, drug detection and other fields, this paper thoroughly studies the application of pressure level ...

The non-contact liquid level sensor uses the sensing capacitance of water to detect the presence of liquid approaching the sensor.

These compact electronic sensors can detect liquid level through non-metallic containers (such as plastic, glass, and ceramics) and the outer wall of pipelines without direct contact with the liquid.

SHANGHAI, June 13, 2023 /PRNewswire/ — Accurate liquid level detection is an important premise and guarantee to realize the relevant functions of household appliances. The NSPGD1 recently launched by ...
