Magnetic Level Gauge: A Reliable Solution for Visual Liquid Level
The Model YLMW500 Magnetic Level Gauge is a highly reliable and versatile level measurement instrument designed for continuous visual indication of liquid levels in various industrial containers such as tanks, reactors, boilers, and vessels. It operates on the fundamental principles of buoyancy and magnetic coupling. A magnetic float, housed within a primary tube (body pipe), rises and falls with the liquid level. This movement is magnetically coupled to an external indicator assembly, causing magnetized flip segments (or flaps) to rotate 180 degrees. The segments are typically colored red and white, providing a clear and intuitive visual reference: red indicating liquid level and white indicating the empty space above. The YLMW500 model is renowned for its robust construction, excellent sealing properties, and adaptability to challenging process conditions including high pressure, high temperature, and the presence of corrosive media.

Features & Advantages
Clear Visual Indication: Highly visible red/white flip segments provide intuitive level reading even from a distance. Panels are often widened for better visibility. Night-readable versions are available.
High Sealing & Safety: The indicator assembly is completely isolated from the process medium, preventing leaks and enhancing safety, making it ideal for hazardous, toxic, or corrosive fluids .
Robust Construction: Designed for demanding applications, capable of withstanding high pressure and high temperature conditions.
Wide Application Range: Suitable for a diverse range of liquids, including water, oil, chemicals, and corrosive media (when equipped with appropriate wetted materials like PTFE or PP linings).
No External Power Required: The basic visual indicator function operates without electricity, enhancing reliability and safety in volatile areas.
Optional Accessories: Can be equipped with proximity switches for alarm functions or 4-20mA transmitters (e.g., based on dry reed technology) for remote level signal transmission.
Low Maintenance: Simple design with minimal moving parts reduces maintenance needs.
Typical Applications
The YLMW500 Magnetic Level Gauge is widely used across numerous industries for level measurement and monitoring in:
Petrochemical Industry: Storage tanks, reaction kettles, separators.
Chemical Processing: Various vessels handling corrosive chemicals, acids, alkalis.
Power Generation: Boiler drum level (often in high-pressure/temperature designs).
Water & Wastewater Treatment: Water tanks, processing vessels.
Pharmaceutical & Food Industry: Suitable for applications where cleanliness is important (requires appropriate material certifications like SS316L or sanitary fittings)
