Electric control noninvasive installation type buoy level meter

Abstract

The invention relates to the technical field of liquid level measurement, in particular to an electric control noninvasive installation type buoy liquid level meter which comprises a top measuring unit, a bottom detecting unit fixed to the lower end of the top measuring unit, an electromagnet and an adjusting motor. According to the electric control noninvasive installation type buoy liquid levelmeter, an internal telescopic adjusting pipe controlled by the adjusting motor is installed in a lateral connecting pipe, and a lateral containing groove internally provided with an elastic overturning control support is formed in the outer side face of the internal telescopic adjusting pipe; the lateral connecting pipe is fixedly installed on the outer wall of a container to be measured through the elastic turnover control support, punching is not needed during installation and fixation, the requirement for the installation position is low, and the application range is wider. An external manual control support is installed on the outer side of a threaded sealing cover, people can select different adjusting and control modes according to needs, and therefore the liquid level meter is simpler and more convenient to use and operate.

Description

technical field [0001] The invention relates to the technical field of liquid level measurement, in particular to an electronically controlled non-invasive installation type float liquid level gauge. Background technique [0002] For the measurement of the liquid level, interface level and density of liquid, there are three kinds of liquid level gauge structures commonly used at present. The first is the torque tube type, which drives the sensor through the displacement of the torsion bar; the second is the spring type, which The buoyancy change affects the elastic force change, changes the spring displacement, drives the magnetic steel, and outputs the liquid level signal through the cooperation of the magnetic coupling and the magnetic sensor. This structure is greatly affected by the medium on the spring, and the accuracy is not good and the repeatability is poor; the third type It is a shaft-sealed diaphragm type, which uses the shaft-sealed diaphragm as the fulcrum to m...

Problems solved by technology

[0004] At present, most of the connecting liquid guiding mechanisms used in electric displacer liquid level gauges on the market are simple and fixed in structure, and need to be installed and fixed by opening holes in the liquid storage container. The installation method is limited, and the requirements for the installation position are relatively high. Special tools are also very troublesome to operate
