When the sensor of the China AnHui TianKang magnetostrictive level sensor works, the circuit of the sensor will stimulate the pulse current on the waveguide wire, which will produce pulse current magnetic field around along the waveguide wire. Outside the sensor's measuring bar is equipped with a floater, which can move up and down along with the changes of the liquid level. Inside the floater there is a group of permanent magnetic ring. When the pulse current magnetic field meets with the magnet ring's magnetic field produced by the floater, the magnetic field around the floater will change, thus making the waveguide wire made out of magnetostriction materials produce a torsional wave pulse in the position of the floater. This pulse returns at fixed speed along the waveguide wire and is detected by the detection institution. By measuring the time difference between the pulse current and the torsional wave, we can accurately confirm the position of the floater, i.e. the position of the liquid level.
