The DM231 is an explosion proof level sensor with Modbus RTU digital output (optional analog output converter available) for total level, interface level and temperature sensor outputs.

The temperature sensors are evenly distributed over the active length of the rigid 316SS tube. and will float on the individual levels for instance oil and water in the same tank.

Calibration is not needed, and installation of the level and temperature measurement instrument is very simple, when installed the accuracy is 0.01%.
