As you can probably imagine, we get tips on a lot of really interesting projects here at Hackaday. Most are pretty serious, at least insofar as they aim to solve a specific problem in some new and ...

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 ...

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 ...

Recently I came across some non-contact liquid level sensors and gathered them out of curiosity. They have been available in the market for the past few years, but this time I was lucky enough to get ...

A pressure transmitter can be used to establish the liquid level in a river, tank, well, or other body of liquid. The pressure at the bottom of a liquid filled container is directly connected to the ...

LVDTs sometimes work better than pressure sensors for gauging tank volumes. A common way of measuring the level of liquid in a tank places a low-pressure sensor at the bottom. The pressure readout is ...
