Jinhu Hongchuang liquid level meter with remote transmission magnetic flap

Overview
The remote transmission of electric signals of the liquid level gauge with remote transmission magnetic flap is realized by the combination of the basic type and the liquid level remote transmission device. The liquid level remote transmission device consists of a type resistance sensor and a type/conversion module. The sensor of the transmitter is fixed on the outside of the main conduit of the magnetic flap level gauge in a bundled form, so that it is in the same magnetic coupling system of the level gauge. . When the magnetic float moves up and down with the liquid level, the reed switch corresponding to the liquid level position is attracted by the magnetic field in the float, and the resistance of the resistance chain changes. The changing resistance signal is converted into a two-wire-standard signal output through the conversion module. , this signal can be easily used with electric instruments and display instruments, and can also be used with light column indicators and digital display adjustment alarm instruments, so as to achieve the purposes of display, control, adjustment and alarm.
Working Principle
The liquid level meter with remote transmission magnetic flap is developed based on the principle of buoyancy and magnetic coupling. When the liquid level in the measured container rises and falls, the float in the main tube of the liquid level gauge also rises and falls. The permanent magnet in the float is transmitted to the field indicator through magnetic coupling, driving the red and white columns to flip. When the level rises, the flip column turns from white to red. When the liquid level drops, the flip column turns from red to white. The red and white boundaries of the indicator are the actual height of the medium liquid level in the container, thereby realizing the liquid level. instruct.
Applicable objects
The liquid level meter with remote transmission magnetic flap can be widely used in various liquid storage tanks, storage tanks, and liquid storage pools in petroleum, chemical industry, oil field, medicine, food, wine and other industries. , reaction tanks, liquids in fermentation tanks, oil fields, liquefied gas, liquid hydrogen, strong acid and alkali liquids, weak acid and alkali liquids, power plant boiler drums, high and low additions, deaerators, drain tanks, return water tanks, high and low pressure heaters, It is mainly used to measure and display the liquid level, liquid surface and interface between two different media in condensers and evaporators that are compatible with liquid media such as + (polytetrafluoroethylene), + (polytetrafluoroethylene), and other pressure vessels. There are a variety of installation forms for you to choose from to meet the requirements of different occasions and environments.
Features of the liquid level meter with remote transmission magnetic flap
It is suitable for liquid level and boundary level measurement of pressure vessels. It can integrate on-site instructions, remote transmission output and control alarm.
The instructions are novel and the readings are intuitive and eye-catching. The viewing angle can be changed according to user convenience.
, Large measuring range, not limited by tank height.
The indicating mechanism is completely isolated from the measured medium, so it is well sealed, highly reliable and safe to use.
, high temperature resistance, non-fading ceramic flip column can be used.
, simple structure, easy installation and low maintenance cost.
