The continuous level transmitter works with a float (built-in magnet), sliding on a vertical stem. Change to the fluid level causes the float to rise or drop vertically. The magnet actuates mono-stable Reed contacts; they are equipped with resistors, all fixed on an internal ruler. Then, the resistance value varies as the fluid level changes. Depending upon total resistance, the measuring transducer generates a signal proportional to the fluid level as a 4-20 mA or Ohm output signal. The RTM is adapted to our level indicator and controllers MAGTOP, SFA, MNR 6 and MNR 7.

The maximal length is 1500 mm; any other longer stem feasibility may be on special study.
