    Tips: What is a magnetic flap level gauge?

    A magnetic flap level gauge is a device used to measure the liquid level in a tank or vessel. It consists of a magnetic float and a magnetic flap indicator. ATO magnetic float is a buoyant object that floats on the surface of the liquid inside the tank. It is typically cylindrical in shape and contains a permanent magnet. As the liquid level changes, the float moves up and down accordingly.

    The magnetic flap indicator is a separate component located outside the tank. It contains a magnetically responsive flap that is connected to the magnetic float inside the tank through a shaft or linkage. The flap rotates based on the position of the float, indicating the liquid level.

    The magnetic interaction between the float and the flap allows for a visual indication of the liquid level without the need for direct contact between the liquid and the indicator. This makes it suitable for measuring the level of corrosive, hazardous, or high-temperature liquids.

    The position of the magnetic flap is typically marked with a scale or graduated markings to provide a clear and easily readable level indication. Some magnetic flap level gauges may also include features such as high and low-level alarms or switches to provide control signals based on specific thresholds.

    Magnetic flap level gauges are commonly used in various industries, including chemical processing, oil and gas, water treatment, and storage tanks, where accurate and reliable level measurement is essential for process control and inventory management.
