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


  • Dual set points makes the sensor typically replace two sensors
  • Simple calibration steps
  • Accurate measuring system
  • Maintenance free device
  • Capable of measuring solids and liquids
  • Suitable for conductive and non-conductive liquids
