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 ...

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 ...

Liquid level measurement technologies form a pivotal component in modern industrial, environmental and agricultural applications. These systems range from optical and capacitive methods to ultrasonic ...

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 unit features an AISI 303-stainless-steel housing, a scratch-resistant glass prism, and fully potted optical parts for an IP68 protection level making it impervious to most harsh liquids. Two ...
