Theres No Alternative To ReliabilityThats why variable area flowmeters from Crystal offer not only the maximum possible accuracy but also maximum reliability.
Origin Of Metal Tube RotameterIt 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 determines the flowrate.
Digital Variable Area Flow MeterThe 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. This got an inbuilt two wire transmitter just provide 24 VDC. And take 4 20 mA signal.
Benefits of CRYSTAL Variable Area FlowmetersLocal indication without the need for auxiliary power.Minimum pressure losses. Easy to read.Accurate measurement even at higher flow (150 m3/hr).Suitable for low flow (8LPH) Default inbuilt transmitter of 4 20 mA (Loop powered).No movement assembly reducing the maintenance.

Operations
Electromagnetic Flowmeters are based on Faradays law of Electromagnetic Induction.In a Electromagnetic Flowmeter, magnetic field is generated by a set of coils. As the conductive liquid passes through the electromagnetic field, an electric voltage is induced in the liquid, which is directly proportional to its velocity. This induced voltage is perpendicular to both the liquid flow direction and the electromagnetic field direction. The voltage sensed by the electrodes is further processed by the transmitter to give standardised output signal or displayed in appropriate Engineering Units on LED Display.The flux density of the electromagnetic field in a given Flowmeter and the distance between the electrodes are constant, therefore, the induced voltage is only a function of liquid velocity.
