Magnetic Level Gauge & Indicator
Magnets can do something quietly remarkable: they can pass a message through a solid steel wall. A magnet inside a tank moves, and a second set of magnets outside the wall moves with it, without a single drop of liquid ever leaving the vessel. That simple trick is the reason a magnetic gauge can show the level of a hot, toxic or flammable liquid safely, from a metre away.
At Levtron Instrument Pvt. Ltd. in Pune, we build it as the Magnetic Level Gauge & Indicator, model LMLT-2100LT. It’s designed as a robust alternative to glass level gauges, and it comes with a bright visual indicator, optional switches and an optional transmitter. One compact instrument can show, alarm and report the level of the same tank.
What Is a Magnetic Level Gauge & Indicator?
A magnetic level gauge, also called a magnetic level indicator, is a visual level instrument built from three main parts: a float chamber, a float and an indicator system. The chamber is a non-magnetic pipe connected to the tank, so the liquid inside it sits at the same level as the liquid in the tank.
The float inside carries magnets that create a 360° magnetic field. As the float rises and falls, it moves coloured flappers or a capsule on the outside of the chamber. You read the level from the indicator, and the process liquid never touches it.
Why Choose Magnetic Level Gauges From Levtron?
A gauge sits on a tank for years, so it pays to choose carefully. Here’s what buyers tend to like about working with us:
- Side or top mounting: Both are available, so the gauge fits above-ground tanks, process vessels, underground tanks and sumps.
- Materials for your liquid: Wetted parts come in SS 304, SS 316, SS 316L, PP and PVDF, with other materials on request.
- Made in India and tested: Each gauge is made in India and is 100% tested and calibrated before it reaches you.
- Built to order: Length, connections, indicator type and accessories are chosen from a clear ordering code.
- Round-the-clock support: Our team provides remote support at any hour, so a question doesn’t wait until Monday.
Applications of Magnetic Level Gauges
Any plant that stores aggressive, flammable, hot or pressurised liquids can use a magnetic level gauge. Here are the common cases:
- Fuels and oils: Diesel, petrol, kerosene, hydraulic oil, lube oil and crude oil tanks all need a clear, safe reading. A sealed chamber keeps the liquid away from the indicator.
- Chemicals, acids and solvents: Sulphuric, hydrochloric and nitric acids, caustic alkalis and solvents like acetone and toluene are tough on glass. Wetted parts in PP, PVDF or stainless steel handle them.
- Syrups, beverages and dairy: Sugar syrup, molasses, juices, beer and milk tanks can be read through a clean indicator. Tri-clover connections are available for hygienic fitting.
- Water, boiler feed and condensate: Boiler feed water, RO water and DM water tanks run hot or under pressure. The gauge shows level without a fragile glass tube.
- Reaction vessels and boilers: Side-mounted gauges connect to tank nozzles on process vessels, distillation towers and power plant boilers. They show the level where operators can see it.
- Underground tanks, sumps and reservoirs: Top-mounted gauges hang from the top flange on a float rod and guide tube. They suit vessels with no side nozzle.
Wherever liquid is stored under tough conditions, a magnetic gauge gives a reading you can trust.
Salient Features of Magnetic Level Gauges
Here’s what you can expect from the Levtron LMLT-2100LT:
- Two indicator designs: A bi-colour flapper shows red for liquid and white for vapour, rotating 180° as the float passes. A follower capsule moves inside a sealed glass tube instead.
- Flexible length and mounting: Centre-to-centre distance runs from 300 mm to 6000 mm. Side or top mounting suits most vessels.
- Switches and a transmitter: Adjustable reed or micro switches give high and low signals. A reed transmitter gives 4-20 mA with HART, 0-10 V or RS485 output at 5 mm or 10 mm resolution.
- Practical limits and fittings: Stainless steel handles up to 150°C and 10 kg/cm². Polypropylene handles 70°C and 2 kg/cm², with higher ratings on request.
- Connections and valves: Flange, thread, tri-clover and union connections are available. Vent and drain come as plugs or ball valves, and an isolation valve is optional.
All of this adds up to a gauge that’s simple to read and doesn’t need constant attention.
Benefits of Magnetic Level Gauges
Here’s what changes once you replace a glass gauge with a magnetic level indicator:
- Safer plant: The indicator is separate from the liquid, which suits flammable, toxic and pressurised tanks. That protects your people and your site.
- Clear reading, every shift: The bright red and white flappers stand out from a distance. Everyone on every shift reads the same level.
- Alarms and remote data: Switches can raise high and low alarms, and the transmitter can feed your PLC or DCS. You get local and remote monitoring from one instrument.
- Less maintenance: There’s no glass window holding the process, and the design has few parts to wear out. That means fewer shutdowns for repairs.
- Suits tough liquids: Corrosive, hot or hazardous liquids stay inside the sealed chamber. You can trust the reading when conditions get harsh.
For most plants the biggest gain is simple: you stop guessing the level and stop worrying about broken glass.
