Level measurement by air purge method is a basic application of physics in level measurement. This is a simple level measurement method that clarifies basics of physics as well as level measurement. A circular SS level tank is provided with glass tube indicator for visual level indication. An SS pipe of equal length is immersed in the tank. The pipe is connected to a pressure regulator. A small compressor and manometer are supplied along with the system.
