Background

When the sensor of the magnetostrictive liquid level meter works, a circuit part of the sensor excites pulse current on the waveguide wire, and the pulse current magnetic field is generated around the waveguide wire when the current propagates along the guide wire of the wave magnetostrictive liquid level meter. A float is arranged outside a sensor measuring rod of the magnetostrictive liquid level meter, and the float can move up and down along the measuring rod along with the change of the liquid level. A group of permanent magnetic rings is arranged in the floater. When the pulse current magnetic field meets the magnetic ring magnetic field generated by the floater, the magnetic field around the floater changes, so that the waveguide wire made of magnetostrictive material generates a torsional wave pulse at the position of the floater, and the pulse is transmitted back along the waveguide wire at a fixed speed and is detected by the detection mechanism. The position of the float, i.e. the position of the liquid level, can be accurately determined by measuring the time difference between the pulse current and the torsional wave.
