Metal Tube Rotameter with Transmitter

About Metal Tube Rotameter with Transmitter

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. It has an inbuilt two wire transmitter provide 24 VDC and take 4 - 20 mA signal.Benefits of Digital Variable Area Flow Meters : Local Indication without the need for auxiliary powerMinimum Pressure loss.Easy to readAccurate measurement even at higher flow (150 m 3 / hr)Suitable for low flow (8 LPH)sDefault inbuilt transmitter of 4-20 mA (Loop Powered)No movement assembly reducing the maintenance Technical Specification : Accuracy +/- 1.5% of FSR.
