Structure Principle
The magnetic liquid level gauge operates on principle of Buoyancy and Magnetic Coupling. As the liquid level rise or fall in the vessel, the float in chamber will rise or fall correspondingly (See fig.1). The permanent magnet in the float actuates the white and red rollers to reverse 180°due to magnetic coupling. As liquid level increases, rollers reverse from white to red; while liquid level decreases, rollers reverse from red to white. The red/white interface of indicator shows the actual level of medium in vessel. The rollers material of common level gauge for atmospheric temperature is plastic resin; and for high temperature applications(up to520°C), alumina ceramic rollers with permanent magnet steel armored should be used.

UHZ517T series magnetic level gauge are top mounted--the chamber is on the top of vessel and connected with float and connecting rod, the magnet field of permanent magnet make the level in vessel   to the top chamber and conveys to level indicator, transmitter and switch due to magnetic coupling effect.

Options
LB transmitter imposes the level signals from magnetic system coupling on every dry reed of resistance chain in sensor. It will change output resistance continuously. The measure voltage will change accordingly proportional to the levels in vessel. With transmission transducer, output a two wire 4~20mA analog signal; HART communication protocol is optional.

Tri-magnet (Quadra-magnet) driven level switch

BK-1/EX Tri-Magnet Level Switch, as the most reliable and practical level switch in the world, has bistable memory function. Mounted on the indicator, in the same magnetic coupling system with level gauge, not contact with the process medium, this level switch is high-temperature resistant, explosion proof and shockproof. It utilizes three magnetic coupling burst switches. When the magnetic float (the first magnet steel) in the chamber close to the switch, the second magnetic component will rotate, meanwhile the third magnet steel in the switch will rotate reversely and the push bar will actuate the switch. BK-1H/Ex Quadra-magnet driven level switch is suitable for high temperature applications. The fourth magnetic coupling is used to keep the terminal box far from the high temperature heat source, and working temperature of BK-1H/Ex Quadra-magnet level switch can be up to 420°C.
