Working principle: It consists of two parts: a magnetic indicator and a float. The magnetic indicator is composed of a red and white magnetic flipping column or a magnetic flipping card and a guard plate equipped with a small magnetic steel. When the floating ball equipped with magnetic steel moves up and down with the liquid, the beam magnetic field of the permanent magnet in the floating ball turns the magnetic turning column 180°. When the liquid level rises, the turning column turns from white to red. It turns from red to white to indicate the height of the liquid level. (The color of the flop and the flop can be different, such as blue and red or black and white, etc.). When it is necessary to transmit output, install a reed switch or magnetic sensor transmitter parallel to the magnetic indicator to realize the remote transmission of 4-20mA or 0-10mA current signal; equipped with a liquid level alarm switch, and The upper and lower limits of the liquid level can be alarmed.

Feature: In addition to on-site instructions, it can also be equipped with remote transmitters, alarm switches, and control switches with complete detection functions. The indication is novel, the reading is intuitive and eye-catching. The indicating mechanism is completely isolated from the measured medium, so it has good sealing, high reliability and safe use. The structure is simple, the installation is convenient, and the maintenance cost is low. Corrosion resistance, no power supply, explosion-proof. According to the different installation positions in the container, there are two types of side mounting and top mounting.
