Abstract

The invention discloses a meter used for liquid level, density measurement and measurement of an interface of two kinds of liquid. The meter comprises a drum, a sinker, and magnetic steel and furthercomprises a force sensor, a concave framework and a steel wire rope connecting to the force sensor and the concave framework. The sinker is disposed inside the drum and the magnetic steel is disposedoutside the drum. The magnetic steel is magnetically coupled to the sinker. With the meter, it is no longer difficult to measure liquid level or density in a high-temperature high-pressure medium or ahigh-pressure low-density medium and a high-pressure low-temperature low-density medium. The meter is high in measurement precision, simple in structure, low in manufacture and maintenance cost and convenient to use so that the meter is used widely.

Description

technical field

[0001] The invention relates to an instrument for measuring liquid level, density or interface of two liquids. Background technique

[0002] The existing liquid level, density or two kinds of liquid interface measuring instruments are of great variety and variety, each has its own advantages and disadvantages. for example:

[0003] Patent No. CN86101109 discloses a large-scale and high-precision liquid level automatic display device: the roller pulley moves up and down on the float along the guide rail, and the spotlight on the float illuminates the photosensitive element to realize on-site indication and remote transmission. Its advantage is that it avoids the friction caused by the magnetic coupling force, and its disadvantages include: 1. The circuit structure for power supply to the spotlight is complicated; It cannot be used. When running up and down, the brush will carry medium from the guide rail to the float; 3. The elastic insulating ring has aging...
