● Working principle and structure

Magnetic flip column(Magnetic flip column)The liquid level gauge is based on magnetismExtreme couplingA device specifically designed for liquid level measurement, which cleverly combines principles such as Archimedes' law of buoyancy with the characteristics of mechanical transmissionOn this basis, continuously expanding its scope of use,extendProduce various types of products,While detecting the liquid level, we endow it with more practical functions.

This type of instrument is availableoneaA cavity that accommodates a floating ball（Known as the main body tube or shell）It forms a connector with the container through a flange or other interface; In this way, the liquid level inside the chamber is at the same height as the liquid level inside the container, so the floating ball inside the chamber will rise and fall with the rise and fall of the liquid level inside the container; At this point, we cannot see the liquid level, so we installed a flip column display outside the chamber. When manufacturing the float, we installed magnetic steel at the junction of the float sinking into the liquid and the floating part. When the float rises and falls with the liquid level, its magnetism is transmitted through the shell to the flip column display, pushing the magnetic flip column to flip180°Due to the fact that the magnetic flip column is a cylindrical body composed of two semi cylinders, red and white, it flips180°The color of the rear facing flip column display will change (red below the liquid level, white above), and the height of the liquid level is at the junction of the two colors.

The working principle of the liquid level transmission part (electrical part) of an instrument with a liquid level transmitter (remote transmission of electrical signals) is to use a magnetic float to act on a magnetic spring switch, causing a change in the resistance number connected to the circuit, thereby enabling the sensor part to generate a resistance signal corresponding to the liquid level change. By using a signal converter, the resistance signal can be converted into4～20mAThe current signal. The electronic components of this level gauge have almost no energy storage components such as capacitors and inductors. stackableHARTCommunication protocol can also be usedRS485Bus communication.

In order to expand its scope of use, liquid level transmission devices can be added according to relevant standards and requirements to output various electrical signals. among which,4～20mACurrent signal is a commonly used type. for exampleThe magnetic switch signal can be used to control or alarm the liquid level while monitoring the liquid level; Added on the basis of the flip column level gauge4~20mATransmission sensor, monitoring the liquid level on site while，The changes in liquid level are transmitted to the control room through transmission sensors, cables, and instruments to achieve remote monitoring and control.
