Abstract

The invention relates to a magnetostrictive level gauge and a liquid level measurement method, and belongs to the technical field of magnetostrictive level gauges. The magnetostrictive level gauge comprises a fixator, a plurality of measurement units, a plurality of waveguide wires and a magnetic floater, wherein the plurality of measurement units are fixed on the fixator in sequence along the length direction of the fixator; the plurality of waveguide wires are correspondingly connected with the plurality of measurement units one by one, each waveguide wire is arranged along the length direction of the fixator, and the tail end of the previous waveguide wire extends to the head end of the next waveguide wire; and the magnetic floater is sheathed to the fixator, when a liquid level changes, the magnetic floater upwards or downwards floats along the fixator, and certain waveguide wires are positioned in a magnetic field formed by the magnetic floater on the own. The magnetostrictive level gauge is favorable for guaranteeing measurement accuracy while a measurement range is improved.

Description

technical field [0001] The application belongs to the technical field of magnetostrictive liquid level gauges, and in particular relates to a magnetostrictive liquid level gauge and a liquid level measuring method. Background technique [0002] Magnetostrictive level gauges are mainly used for level measurement of liquids. [0003] When the magnetostrictive liquid level gauge is working, a pulse current is excited on the waveguide wire, and when the current propagates along the waveguide wire, a pulse current magnetic field will be generated around the waveguide wire. There is a magnetic float outside the measuring rod of the magnetostrictive liquid level gauge, and the magnetic float can move up and down along the measuring rod with the change of the liquid level. When the pulse current magnetic field meets the magnetic field generated by the magnetic float itself, the magnetic field around the magnetic float changes so that the waveguide wire made of magnetostrictive mate...
