Digital Metal Tube Rotameter
It operates on the principal 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 moment through a series of linkages and counter weight.The tube and the float combination determine the Flowrate
Digital Meter: 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 flowmeter does not require any electrical connection, since it operates on battery. It has an inbuilt two wire transmitter provide 24 VDC and take 4-20 mA Signal.
