Service intended

The SMT4000 series is a Magnetic float type level transmitter, which uses buoyancy to continuosly measure the water level inside the vessel.
When a float designed/manufactured for the specific gravity of fluid moves up and down due to buoyancy, the Reed switch attached to the sensor detects magnetic in the float and changes its resistance value. You can measure the water level inside the vessel with the converted current value.
