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)
