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 ...

AutomationDirect has added the Flowline EchoTouch, EchoSpan, and EchoSwitch lines of ultrasonic liquid level sensors and transmitters, as well as the PodView digital level indicator to their product ...

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 ...

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 ...

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 ...
