Features of Magnetic Level Gauges (Magnetic Level Indicators)

Magnetic level gauges, also known as magnetic level indicators, are routinely used to provide a display of liquid level in tanks and other vessels. Their popularity stems from their high visibility from distances and non-invasive design which reduces the possibility of leak points and the risks of fugitive emissions.



"Mag Gauge" construction is fairly simple. A magnetic float, designed for the specific gravity of the material being measured, rides inside a vertical pipe on top of the process media. A gauge with magnetically coupled visual indicator is fastened to the pipe. As the media inside the pipe rises and falls, the visual indicator moves in the same fashion.



Magnetic level gauges are often employed in tandem with magnetostrictive, guided wave radar, or other measurement means to provide a reliable local display of liquid level, as well as an electrical signal that can be transmitted to recording instrumentation or controllers.


The features of magnetic level gauges include:
  • Low maintenance. 
  • Wide operating temperature and pressure range.
  • Visual tank level indication. 
  • Continuous level measurement.
  • Easier to read from greater distance than glass sight gauges. 
  • Can be applied to wide fluid level ranges with a single instrument. 
  • Break resistant, sturdy.
  • Wide range of construction materials available.
  • External mounting of ancillary indicators, switches, and transmitters with isolation from process media. 
  • No electric power required for operation.

There are a number of options available so you can customize the level indicator for each specific application.  The best way to proceed is to combine your process knowledge with that of a product specialist.  Collectively, you'll be able to achieve an effective solution to your application challenge.
