In the field of industrial automation liquid level measurement, Xingzhou Yuanchuan magnetic flap level gauge has become the core equipment for monitoring the liquid level of high-risk media in industries such as power, petrochemical, metallurgy, etc., thanks to its non-contact measurement principle and multiple technological advantages. This article analyzes its technical value from three dimensions: working principle, technical characteristics, and application scenarios.

1、 Principle of magnetic coupling non-contact measurement

This level gauge is based on the buoyancy law and magnetic coupling effect to achieve level monitoring. When the liquid level in the tested container rises or falls, the float in the main tube moves synchronously with the liquid level. The permanent magnet steel embedded inside the float penetrates the wall of the main tube through the magnetic field and produces magnetic coupling with the red and white flip column in the on-site indicator. When the liquid level rises, the magnetic drive flips the column over180°From white to red; When the liquid level drops, the flipping column reverses and returns to white. This mechanical magnetic transmission structure achieves complete isolation between the measuring components and the measured medium, fundamentally avoiding the defects of traditional glass tube level gauges that are prone to breakage and adhesion.

2、 Five core technological advantages

Maintenance free and long-lasting

The design without mechanical transmission components breaks through the lifespan of the equipment10Year. The continuous operation records of a chemical enterprise show that under the maintenance strategy of twice a year standard calibration, the equipment has been running continuously without any faults8.3Ten thousand hours.

Multi parameter integration capability

By installing magnetostrictive sensors or reed tube arrays, simultaneous measurement of liquid level, interface, and temperature parameters can be achieved. In the application of oil-water separation tanks, a single device can achieve real-time monitoring of oil layer thickness, water layer height, and medium temperature.
