Magnetic level gauges, also referred to as magnetic level indicators, are routinely used to provide a display of liquid level in tanks and other vessels. They 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 favorable attributes of magnetic level gauges include:
- Continuous level measurement
- Operable without electric power
- Direct visual tank fluid level indication, regardless of tank shape or profile.
- Wide range of operating temperature and pressure
- Breakage resistant construction
- Range of construction materials available to accommodate corrosive media
- Measuring indicators, switches, and transmitters mounted externally, without contacting the medium being measured.
- Low maintenance operation.
- Readable level indication from greater distance than glass sight gauges.
- Applicable to large fluid level ranges with a single instrument.
