Magnetic liquid level meter

Abstract

The invention discloses a magnetic liquid level meter comprising a barrel body. The barrel body is internally provided with a magnetic floating member and a liquid level indicator which is magnetically coupled with the magnetic floating member is arranged outside the barrel body; the magnetic floating member is a ball chain which is composed of a plurality of balls which are connected in series; and one ball in the ball chain is internally provided with a magnetic device. When the magnetic liquid level meter works, a liquid to be tested is injected from a connector at the lower part of the magnetic liquid level meter; and the ball chain floats along with the rising of the liquid level and magnetic balls in the indicator are magnetically coupled with the magnetic device at the same time, so that the magnetic balls are reversed and parts of the magnetic balls become to a state that the front sides are red and the back sides are white from a state that the front sides are white and the back sides are red. The color changing condition of the magnetic balls is the liquid level changing condition of the liquid. In the magnetic liquid level meter, the ball chain is adopted as the magnetic floating member; the balls have a higher pressure-bearing capability and the buoyancy force can be continuously increased through increasing the number of the small balls, so that the magnetic liquid level meter is suitable for a scene with high pressure and low density.

Description

technical field [0001] The invention relates to a liquid level gauge, in particular to a magnetic liquid level gauge suitable for high-pressure and low-density sites. Background technique [0002] Liquid level gauges are widely used in various containers such as towers, tanks, tanks, kettles, and boilers. According to different structures, liquid level gauges are divided into glass tube type, glass plate type, magnetic type, and buoy (barrel) type. Magnetic liquid level gauges are suitable for liquid level measurement under high temperature, high pressure, corrosive conditions, etc., and have reliable safety, so they are widely used at home and abroad. [0003] The traditional magnetic liquid level gauge designs a cylindrical liquid storage chamber equal to the height of the measured container, also known as the cylinder; then designs a fully enclosed cylinder with an outer diameter slightly smaller than the storage chamber, also known as the buoy, and installs a strong magn...

AI Technical Summary

Problems solved by technology

When the container is fed, the liquid to be measured is measured from the lower interface of the magnetic liquid level gauge. When the liquid level is close to the upper flange, the distance from the upper flange to the top of the cylinder will suffocate inside, causing the buoy to stop rising, so it is often at this stage In case of unstable or false liquid level
