The MTLT-5000 is based upon the magnetostrictive principle. The sensing tube contains two wires which are pulsed with the magnetic field created by the magnetic float causes a torsion stress wave to be induced in the wire.
The torsion propagates along the wire at a known velocity from the position of the magnetic float and toward both ends of the wire.
The microprocessor-based electronics measure the elapsed time between the start and return pulses and convert it into 4-20 mA DC output which is proportional to the level being measured.
