How do liquid level indicators work?
The visual indication operates absolutely energy-free and simply follows the principle of communicating vessels. Independent from the process controller, a WEKA Magnetic Level Indicator provides an on-the-spot visual readout even during system failure or mains power loss. Visual level indicators are preferred where it is not possible to install an indicator outside.

Indicator Flaps and SS Floats
- Stability: Bar Magnets in indicator flaps interlock with each other and maintain stability, even when large disturbances and shocks are applied to the indicator.
- Visibility: A visible event from 100Mtr away.
- Weight: Weka Bar magnets in floats make the float very light.
- Design: A smaller float is a big advantage.
- Sedimentation: Distance between float wall and tube wall is high - no problem with sedimentation.
- Customisation: Floats are custom-made according to fluid density.
- Longevity: Weka uses AlNico Magnet (after 10 years, the magnet can be re-magnetised and reused).
Applications
Chemical, oil and gas industry
Our level indicators are widely used in the chemical, oil and gas industries. These industries prefer level indicators as they deal with extreme pressure or temperature and corrosive or toxic fluids. Our level indicators are ideal for monitoring liquid levels in closed vessels.
- Off-shore and on-shore installations
- Crude oil intermediate storage tanks
- Gas and oil separators
- Polyester production
- Boilers
- Tank Farms
Chemical and Pharmaceutical Industry
One big challenge that the chemical and pharmaceutical industries face when measuring liquids is -- toxicity and corrosion. To address this problem, our level indicators come are made from corrosion-resistant materials. They can be easily used in:
- Dosage and intermediate storage tanks
- Desalination plants
- Water purification plants
- Tank farms
- Systems in chemical process engineering
- Cooling systems
Shipbuilding industry
Level indicators are used in the shipbuilding industry for measuring various fluids on board. Our tank level indicators are used for measuring liquids such as:
- Fresh water
- Waste water
- Fuel
- Lubrication
- Incineration plants
- Boiler
- Tank farms
Water management systems
At a time, when all over the world there’s a crisis of water, wastewater management and water treatment have become very important. For water treatment, whether for drinking or for industrial use, accurate measurement is essential. Our water level indicator for tanks can be used on:
- Settling pools
- Chemical tanks
- Storage tanks
- Osmosis plants
- Filter systems
As one of the leading level indicator manufacturers, we offer solutions that can solve complex challenges in various industries. If you have any specific requirements, get in touch with us and find out how we can help your business.
