Abstract

The invention relates to a float type liquid level gauge for high temperature and high pressure or high pressure and low density medium, including a float chamber, a float, and a scale. The coupling is equipped with magnetic steel or disc-shaped magnetic steel, which forms a magnetic attraction with the magnetic material sphere in the non-ferromagnetic material float or the disc-shaped magnetic steel in the non-ferromagnetic material float, and is horizontally mounted on the magnetic coupling. The metal shafts on the two side walls are exposed outside the two side walls and are closely attached to the guide rails by the magnetic force, and move up and down along the guide rails driven by the magnetic force. The continuous remote transmission of signals is also realized by winding the resistance wire on the guide rail to measure the change of the loop resistance value. The invention solves the problem of liquid level measurement in high-temperature, high-pressure or high-pressure, low-density media, and has high measurement accuracy, simple structure, convenient use, low manufacturing and maintenance costs, and wide application.

Description

Technical field

[0001] The invention relates to the field of liquid level measurement, in particular to a float type or magnetic float type liquid level gauge for high temperature, high pressure or high pressure and low density media. Background technique

[0002] Liquid level gauge is an instrument with a wide range of applications. There are many types of liquid level measuring instruments available. Now for the high temperature and high pressure container, the medium is highly corrosive or the pressure is high but the medium density is low, the following analysis is made:

[0003] In high pressure or high pressure low density applications, the float type liquid level meter is difficult to manufacture due to high pressure or high pressure and low medium density. For high temperature and high pressure applications, the manufacture of floats is even more difficult: When the strength decreases at high temperature, the wall thickness of the float needs to be increased accordingly.
