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 ...

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 ...

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 ...

The need for accurate and reliable level measurement systems is increased by the demands of advanced automated processing systems, more stringent process control and strict regulatory requirements. By ...

A common way of measuring the level of liquid in a tank places a low-pressure sensor at the bottom. The pressure readout is the product of the liquid column height times the density of the liquid. As ...

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 ...

Drive process engineers require more reliable and precise level measurement systems because of the needs of sophisticated automated processing systems, an increasingly stringent regulatory environment ...

Sensortechnics introduces the new CLD series of non-invasive ultrasonic fluid monitoring sensors. These devices enable continuous bottom-up liquid level detection based on ultrasonic time-of-flight ...

Keurig Dr Pepper. has filed a patent for a beverage machine that can determine the liquid level in a tank without a dedicated sensor. The machine uses a controller to calculate the liquid level based ...
