The float of the metal tube float flowmeter moves the float upward with the change of the flow rate in the measuring tube, and the buoyancy of the float and the gravity of the float reach a balance at a certain position. At this time, the flow annulus area between the float and the orifice plate (or cone tube) remains constant. The area of the annular gap is proportional to the rising height of the float, that is, the float is in the measuring tube, the rising position represents the flow rate, and the changing position of the float is transmitted by the internal magnet to the external indicator, so that the indicator can correctly indicate the flow at this time. value. This makes the indicator housing not in direct contact with the measuring tube, so even if a limit switch or transmitter is installed, the instrument can be used under high temperature and high pressure working conditions

It operates on the principle of variable area; the fluid in the metal tube raised a float in the taper tube increasing the area of passage of fluid. The float moves up in proportion to the rate of flow of fluid and get stabilized when the weight of the float is balanced by the upward hydraulic force. By a magnetic coupling the inner float movement through a series of linkages and counter weight. The tube and the float combination determine the flow rate. The inner float magnetic field is detected by the high sensitive magnetic field detection sensor, enable us to show the digital readout.As such this flow meter does not require any electrical connection, since it operates on battery.
