Cleanable liquid level meter

Abstract

The invention discloses a cleanable liquid level meter. The cleanable liquid level meter comprises a liquid level meter body, wherein a fluid channel in the vertical direction and a cleaning device located above the liquid level meter body are arranged in the liquid level meter body; and the cleaning device comprises a supporting plate, a limiting assembly installed at one side of the supporting plate and used for fixing, a lifting assembly installed on the supporting plate and a cleaning assembly installed on the lifting assembly and used for cleaning the inner wall of the liquid level meter body. According to the cleanable liquid level meter, the lifting assembly drives the cleaning assembly to move along the fluid channel of the liquid level meter to clean the inner wall of the liquid level meter; and a lifting rod A, a lifting rod B, a cable A and the like form the lifting assembly of a telescopic structure, so that the installation space is saved, and meanwhile the movement reliability is guaranteed. The inner walls of liquid level meter bodies with different diameters can be cleaned through the cleaning assembly, so that the flexibility and practicability are greatly improved; and spraying is conducted on the inner wall of the liquid level meter body in cooperation with an annular spraying pipe A and an annular spraying pipe B, so that the problem that the inner walls of existing glass tube liquid level meters cannot be cleaned thoroughly is solved.

Description

technical field [0001] The invention specifically relates to a washable liquid level gauge. Background technique [0002] The height of the liquid medium in the container is called the liquid level. The instrument that measures the liquid level is called a liquid level gauge. The instrument can be used for medium liquid level detection of various towers, tanks, tanks, spherical containers and boilers and other equipment. As the most important working parameter in industrial production, liquid level measurement, together with temperature, pressure and flow, can be called the four major industrial working parameters. [0003] According to different measurement principles, liquid level gauges can be divided into buoyancy, differential pressure, conductivity, ultrasonic, radar and other types. Among them, the glass tube liquid level gauge is a common liquid level gauge used to display petrochemical liquids, especially for on-site liquid level or boundary level measurement and...

AI Technical Summary

Problems solved by technology

However, the existing glass tube liquid level gauge is inconvenient to clean, and the inner wall of the glass tube cannot be cleaned by simply washing with water. Not displaying brings security risks to system operation
