Chongqing Chuanyi MB Series Magnetic Level Gauge

The Chongqing Chuanyi MB Series Magnetic Level Gauge represents an essential, highly reliable solution for direct visual monitoring and continuous level measurement in industrial automation. Built with a robust bypass chamber connected to the vessel, the system operates through magnetic coupling between the internal float and the external indicator rail.

Clear Visual Indication and Magnetic Coupling Inside the sealed chamber, a precision-engineered float rises and falls in direct response to the liquid level. Permanent magnets sealed within the float magnetically interact with the rotating bicolored flaps (typically red and white) on the external indicator column. As the float moves, the flaps flip 180 degrees to display the liquid level clearly, providing high-contrast visibility even from a distance. Because the magnetic coupling is entirely non-contact through the chamber wall, the process fluid is completely isolated from the external environment, preventing leaks or glass breakage.

Robust Construction for Hazardous Environments Designed to withstand severe industrial conditions, the MB series accommodates high pressures, elevated temperatures, and corrosive or toxic liquids. The hermetically sealed design makes it an ideal, safe replacement for fragile glass gauges, especially when handling volatile hydrocarbons, acids, or chemical solvents. Furthermore, the gauge can be equipped with auxiliary magnetic switches or reed-chain level transmitters to convert the mechanical movement into standard 4-20mA or switch signals for remote control systems.

Flexible Installation and Maintenance The unit features standard side-mounted or top-mounted process connections (such as flanged connections) to match various tank designs. Its durable mechanical structure ensures minimal maintenance requirements, providing dependable day-to-day operation in complex process plants.

FAQ

Q1: How does the magnetic level gauge display the liquid level without direct contact? A: A magnetic float inside the sealed process chamber moves up and down with the liquid level. Permanent magnets inside the float drive the external bicolored flaps through magnetic coupling, safely displaying the level without risking fluid leaks.

Q2: Can the MB series be used for corrosive or hazardous chemicals? A: Yes, because the measuring chamber is hermetically sealed and can be manufactured from corrosion-resistant materials, it safely contains toxic, flammable, or aggressive chemicals without the leakage risks of glass gauges.

Q3: Can this level gauge provide remote electrical signals as well as visual reading? A: Yes, while it provides a clear local visual indication, it can also be equipped with optional magnetic switches for point level alarms or a reed-chain transmitter for 4-20mA remote output.

Q4: Is regular maintenance required for the magnetic indicator? A: The MB series requires very little routine maintenance due to its rugged mechanical design and sealed chamber, though periodic checks of the float movement and indicator alignment are recommended.
