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 robust, process industries level sensor is designed to resist contamination while fully meeting the high demands of level monitoring by using the optical principle. The sensor head made of ...

Fluid-level sensing is very common in industrial applications and now is being used in domestic applications to sense water levels in overhead tanks. The greatest challenge for designers is to make ...

Figure 1a shows a slotted optical switch. An LED is mounted in a plastic housing, facing a phototransistor, but separated by a gap. If something moves into the gap, it blocks the light path between ...

Until quite recently, accurate measurement of the level of fluid in a container was remotely obtained using systems that required cumbersome cabling and hardware. Now, Senior Scientist Stan Woodard of ...

For all electrically conductive Fluid or liquid level measurement, this single-chip circuit is very compact and simple. This circuit is a voltage level sensor encouraged the AC bias supply for the ...

We often write a post and then learn something new and cool from the comments. The same thing happened when [Andreas] posted a video about monitoring fluid levels. Commenters told him that the best ...
