The
304 explosion-proof remote transmission magnetic flap level gauge is a highly reliable and safe instrument designed for continuous level measurement in hazardous industrial environments. Constructed with 304 stainless steel, this level gauge combines durability, corrosion resistance, and explosion-proof capabilities, making it ideal for applications in chemical, petrochemical, pharmaceutical, and oil and gas industries where flammable or explosive substances are present.
Design and Functionality
The level gauge consists of a chamber filled with magnetic floats that rise and fall with the liquid level. Attached to the exterior of the chamber is a row of magnetic flaps （or indicators） that flip to reveal a contrasting color （typically red for liquid and white for gas） as the float passes, providing a local visual indication of the
LIQUID LEVEL.
For remote monitoring, the gauge is equipped with a built-in reed switch transmitter or a Hall effect sensor, which converts the magnetic field changes caused by the float into electrical signals. These signals are then transmitted over long distances （typically 4–20 mA or digital protocols like HART） to a control room or display unit, enabling real-time level tracking and automation.
Key Features
Explosion-Proof Design: Compliant with international standards （e.g., ATEX, IECEx）, it ensures safe operation in explosive atmospheres.
Corrosion Resistance: 304 stainless steel construction withstands aggressive chemicals and harsh environments.
High Accuracy: Magnetic coupling ensures precise level detection without mechanical wear.
Remote Transmission: Enables centralized monitoring and integration with process control systems.
Low Maintenance: Simple structure with no moving parts reduces downtime and maintenance costs.
Applications
This level gauge is suitable for measuring levels in storage tanks, reactors, and distillation columns containing volatile or combustible liquids. Its explosion-proof certification makes it indispensable in safety-critical processes, such as in refineries, chemical plants, and LNG facilities.
In summary, the
304 explosion-proof remote transmission magnetic flap level gauge offers a robust, accurate, and safe solution for level measurement in hazardous environments, combining local visual indication with remote monitoring capabilities.
