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 ...

Here is a design concept for a cheap single point optical liquid sensor that can detect the presence or absence of certain colored liquids inside a transparent tube. It can be tailored to output a ...

This digital optical liquid-level sensor is said to be versatile enough to be mounted at any angle and at the top, sides, or bottom of a vessel. Measuring just 30.25 mm x 19 mm, the sensor houses an ...

The company’s optical liquid-level switches are made with flat glass, which eliminates contamination problems associated with the 90-degree cone normally used in these types of switches and provides a ...

Spanish researchers describe the design and development of a prototype liquid level sensor that exploits the changes in light transmittance in a plastic optical fiber cable. Dr Lomer and colleagues ...

In contemporary dialysis instruments designed for hemodiafiltration, hemofiltration and hemodialysis, a variety of sensors are employed, allowing the monitoring of liquid level, flow and pressure in ...

The Series 1010 synthetic optical-fiber sensor does contact-level detection in all nonmilky-white liquids. The unit features an AISI 303-stainless-steel housing, a scratch-resistant glass prism, and ...
