The Magnetic Level Gauge offers a safe, reliable, and highly accurate solution for continuous liquid level indication.

Designed for a wide range of industrial applications, it eliminates the need for direct contact with the process fluid, providing clear visibility of the liquid level even under harsh operating conditions.The Magnetic Level Gauge is a superior alternative to traditional sight glass indicators, especially in applications involving hazardous, high-pressure, or high-temperature fluids. Its unique design utilises a float containing magnets that move within a chamber parallel to the main vessel. As the float rises or falls with the liquid level, it causes external magnetic flags or rollers to flip, providing a clear, visual indication of the level on a scale. This non-invasive measurement technique ensures operator safety by isolating the process fluid from the indicator.  
 Key Industries/Applications:

  • Industries: Power generation, oil and gas, chemical and petrochemical, pharmaceutical, food and beverage, water treatment, and general industrial applications
  • Applications: Boiler drum level indication, storage tanks, process vessels, condensers, heat exchangers, and any application requiring safe and reliable liquid level monitoring 

Technical data

  • Product capacity / performance range: Designed for continuous liquid level measurement, it can handle a wide range of pressures, temperatures, and fluid densities. Specific ranges depend on the model and application
  • Compliance or standards: Designed and manufactured to meet relevant industry standards for pressure vessels and instrumentation
  • Design and customisation:  
    • Side-mounted or top-mounted configurations
    • Choice of materials (e.g., stainless steel, special alloys) for compatibility with various corrosive or aggressive fluids
    • Optional accessories include level switches (reed switches or magnetic switches) for alarms or pump control, and level transmitters (magnetostrictive or guided wave radar) for remote indication and integration with DCS/PLC systems
    • Insulation options for high-temperature applications or frost protection
    • Various process connections (flanged, threaded)
