Magnetic Level Gauges

Magnetic Level Gauges

Magnetic Level Gauges (MLG) are widely used in the monitoring and process control of liquid level and interface in various industries, including petroleum, chemical, power, paper, metallurgy, and water treatment. They are appropriate for real-time, precise, safe, and dependable continuous process level measurement. 

The magnetic level gauge provides real-time level and interface measurement based on magnetic coupling and buoyancy principles, where the process vessel bolts to the Magnetic Level Gauge (MLG). A float with a 360° magnetic ring is inside the gauge chamber. Outside the chamber, there is an indicator with a vacuum glass tube containing a bi-colored two-face magnetic bargraph. The float moves in response to the level movement, causing the magnetic bargraph to turn and change color. Alternatively, a magnetostrictive transmitter provides a continuous analog or digital output.

The accurate liquid level is indicated or "read." The indicator employs hermetically sealed glass tube technology to show the process level clearly. It eliminates the common problems associated with glass gauges, such as vapor, condensation, and liquid leakage, among other things.

Typical Applications for Magnetic Level Gauges:
  • Boiler: Steam drum liquid level
  • Power generation: Auxiliary machinery liquid level (HP reheater, LP reheater, de-aerator, condenser and heating network heater etc), chemical water
  • Coal Chemical: Methanol, dimethyl ether, synthesis ammonia/urea, MTO, CTL, SNG
  • Silicon industry: Organic silicon, polycrystalline silicon
  • Petroleum and petrochemical: Oil and gas, ethylene, trimerization and etc.
  • Fine Chemicals: Methane oxide, epoxy ethane, aniline, PTMEG, BDO, carbon fiber, POM, acetic acid, styrene, rubber, crude benzol refining
  • Others: Metallurgy, paper-making, water treatment, biological, pharmaceutical, food and beverage etc.
