The Magnetic Level Gauge model BNA is a robust, reliable instrument used to measure and display the liquid level in a tank or vessel. It operates without any electrical power supply and provides continuous level indication based on the height of the liquid within the vessel. The system consists of a bypass chamber connected to the vessel by at least two process connections (flanged, threaded, or welded). This setup ensures that the liquid level in the bypass chamber corresponds directly to the level inside the vessel.

A float with a built-in permanent magnetic system is mounted inside the bypass chamber. This float moves in accordance with the liquid level and transmits the level contact-free to a magnetic display on the outside of the bypass chamber. The display consists of two-colored plastic rollers or stainless steel flaps that rotate through 180° based on the magnetic field of the float, providing a clear visual representation of the liquid level. The level indication transitions from white to red as the liquid level rises and from red to white as the level falls.

Features:

• Continuous Level Indication: Offers real-time level indication without the need for an external power supply.
• Proportional Level Indication: The level displayed is directly proportional to the height of the liquid, providing accurate readings.
• Corrosion-Resistant Materials: Customizable design options and use of materials resistant to corrosion, ensuring suitability for a wide range of industries.
• Versatile Operating Conditions:
  • Temperature: Operates in a wide range of temperatures from -196°C to +450°C.
  • Pressure: Can withstand pressures from vacuum to 400 bar.
  • Density: Suitable for fluids with a density greater than 340 kg/m³.
• Various Process Connections: A wide selection of different process connections and materials are available to suit specific requirements.
• Modular Options: Mounting of level transmitters and magnetic switches can be added as optional features.
• Explosion-Protected Versions: Available in explosion-proof versions for hazardous environments.

Applications:

Magnetic level gauges are widely used in many industries due to their ability to operate without power, their versatility, and their robust performance in harsh conditions. Some key applications include:

• Chemical and Petrochemical Industry: For monitoring levels of aggressive chemicals, solvents, and other liquids.
• Oil and Gas Extraction: Both onshore and offshore applications, such as monitoring levels in crude oil tanks or offshore platforms.
• Shipbuilding: Used in marine applications for monitoring fuel, ballast, and other liquid levels on ships.
• Machine Building and Power Generation: For maintaining accurate level measurements in machinery and power plants.
• Process Water and Drinking Water Treatment: Ensures precise level measurement in water treatment facilities.
• Food and Pharmaceutical Industries: Essential for hygienic and non-corrosive environments where product purity is paramount.

By offering reliable level indication under varying environmental conditions, magnetic level gauges are indispensable in industries where precise, continuous measurement of liquid levels is critical.

The UTN Top-Mounted Level Indicator is a reliable, innovative solution for measuring liquid levels in various industries. This instrument consists of a measuring chamber, a float with a guide rod, and a magnetic system. It is designed to be mounted onto a vessel via process connections such as flanges or threads, making it adaptable to different tank configurations. The float, connected to the magnetic system by the guide rod, moves with the liquid level inside the vessel. This movement is transmitted contact-free to a magnetic display located outside the measuring chamber.

The magnetic display features red/white plastic rollers or stainless steel flaps, which rotate 180° depending on the liquid level. As the level rises, the display shifts from white to red, and as the level drops, it changes from red to white. This visual indication of the liquid level is achieved without the need for an external power supply, ensuring energy efficiency and reliability.
