SM642 is suitable for use with liquids and solids.

It’s a very accurate measuring device and the most common measuring technique available.

The sensor has a dual separate set points that makes it the replacement of two level switches The sensor works with conductive and non-conductive liquids

Example (water, oil, gasoline) and fine and coarse-grained solids.
