● Working principle:

Working principle of magnetostrictive liquid level sensor: When the initial pulse is transmitted in the waveguide wire, a rotating magnetic field advancing along the direction of the waveguide wire is generated. When the magnetic field meets the permanent magnetic field in the magnetic ring or float, magnetostrictive effect is generated, which makes the waveguide wire twist. This twist is sensed by the pickup mechanism installed in the electronic bin and converted into the corresponding current pulse, and the time difference between the two pulses can be calculated through the electronic circuit to accurately measure the displacement and liquid level of the measured.
