Technical Field

The invention relates to the field of liquid level meters, in particular to a magnetostrictive liquid level meter.

Background

The height of the liquid medium in the container is called the liquid level, and the instrument for measuring the liquid level is called a liquid level meter. The liquid level meter is one of level meters. The type of the liquid level meter comprises a tuning fork vibration type, a magnetic suspension type, a pressure type, ultrasonic waves, sonar waves, a magnetic turning plate, radar and the like. The liquid level meter is widely applied to observing the liquid level inside a container or equipment, and the existing liquid level meters are various and comprise a pressure liquid level meter, a differential pressure liquid level meter, a floating ball liquid level meter, an ultrasonic liquid level meter, a glass tube type liquid level meter, a magnetic liquid level meter and the like. The magnetic liquid level meter is made up according to the principle of buoyancy and magnetic coupling, and has the direct-reading feature of on-site display. The magnetic turning column level meter is the most widely used magnetic level meter at present and consists of a liquid level pipe with a magnetic float inside, a connecting pipe communicated with a container and a display panel with a magnetic turning column outside the liquid level pipe. The magnetic turning column is a cylinder and is arranged in the display panel, half of the outer surface of the magnetic turning column is red, and half of the outer surface of the magnetic turning column is white, when the magnetic floater moves up and down along with the change of the liquid level, the magnetic turning column can turn around a shaft, when the magnetic floater ascends, the corresponding magnetic turning column turns from white to red and faces the display panel, when the magnetic floater descends, the corresponding magnetic turning column turns from red to white and faces the display panel, and therefore the liquid level in the container is displayed.

This kind of magnetism turns over post level gauge exists when the liquid level changes in the container, and the magnetism float can receive the liquid stream impact to cause the atress inequality to block easily and rotate, causes the little cylinder of magnetism board of turning over and can not in time overturn some not overturns that the upset appears, causes the confusion for the reading to do not set up the shortcoming of recovery unit. In order to improve it, a magnetostrictive level gauge is therefore needed to solve this problem.
