Safe and Cost Effective Liquid Level Control with Magnetic Level Gauges and Magnetostrictive Transmitters

Magnetic level gauges are a safe, easy, and dependable way to measure fluid levels inside a tank. These visual indicators are a non-invasive, low-maintenance, cost-effective alternative to sight glasses. Because the fluid never comes into contact with the indicating glass, they are exceptionally safe for flammable, toxic, and corrosive liquids. There is no risk of leakage if the glass ever breaks. 

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

The magnetic level gauge, bolted to the process vessel, provides real-time level and interface measurement based on magnetic coupling and buoyancy principles. IA float is inside the level gauge chamber with a 360° magnetic ring. An indicator with a vacuum glass tube containing a bi-colored two-face magnetic bargraph connects to the outside of the chamber. The float moves in response to the level change, causing the magnetic bargraph to turn and change color. Additionally, a mating magnetostrictive transmitter provides a continuous analog or digital output. 

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

Most Common 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.

Demonstration of Acoustic Wave Technology Used in Industrial Level Applications

Acoustic Wave Technology from Hawk Measurement, utilizes lower frequency sound waves, and is an improved ultrasonic technique. This technology uses lower frequencies to produce higher power, with the additional enhancement by using a uniquely designed piston transducer.

The transmission of high-powered acoustic waves through the environment where the sensor resides ensures minimal losses. Any losses have much less impact than conventional ultrasonic instruments encounter due to the high-powered emitted pulse. This means more energy transfers and more energy returns as a result. Even when noise levels are high, the advanced receiver circuitry is designed to detect low-level return signals. The measured signal is temperature-compensated to give the outputs and the display maximum accuracy.

Typical Industrial Level Applications:

• Power Generation Stations: Boiler bunkers, raw coal bunkers, ash pits, fly ash silos, etc.
• Wastewater / Water Treatment: River level, wet wells, inlet screens, tanks, sumps, pump stations, water towers, dams, basin levels, chemical storage, etc.
• Mining Operations: Crushers, surge bins, ore passes, conveyor profile, blocked chute, stockpile, stackers, reclaimers, storage silos etc.
• Others Applications: Food processing, cement plants, plastics molding, grain storage, chemical processing, pulp & paper

Features of Magnetic Level Gauges (Magnetic Level Indicators)

Magnetic Level Gauge
(Jogler)

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.
