The product

The Vector MLI virtually eliminates maintenance and is a great replacement for hard-to-see, leaky, sight and gauge glass indicators. Optional switches and transmitters are available to provide alarm points and level control.

Magnetic level indicators technology

Magnetic Level Indicators (MLI) have revolutionized the global visual indication market by offering a safer, reliable, and high-visibility alternative to common gauge glass assemblies. Utilizing a combination of proven buoyancy principles along with the benefits magnetism, MLIs can be customized to fit virtually any process connection arrangement on the vessel.

The chamber and magnetic float is available in a variety of materials and pressure ratings to accommodate the wide variety of complex process applications present in the world’s major industrial facilities.


  • Rugged, industrial-grade construction
  • Field adjustable visual indicator for convenient viewing
  • Continuous measuring range up to 216 in. (549 cm.)
  • Compatible with electronic point switches and continuous level transmitters
  • Media specific gravity as low as 0.54


  • Electronic point level switches
  • Continuous level transmitters
  • High temperature insulation

Operating principle

Magnetic Level Indicators (MLIs) rely on a magnetic float that travels up and down with the liquid in a chamber, which is mounted to a pressure vessel or storage tank. The float contains a magnetic assembly that interacts with an externally-mounted visual indicator. As the float follows the liquid, the magnetic field causes highly contrasting flags in the visual indicator to rotate, therby displaying a highly visible representation of the level.

Magnetically-actuated external point switches and continuous transmitters can expand the function of the MLI by providing high or low alarms, as well as real-time level data supplied to the control room (4-20mA, HART, Foundation fieldbus).
