There’s No Alternative To Reliability
That’s why variable area flowmeters from Crystal offer not only the maximum possible accuracy but also maximum reliability.
Origin Of Metal Tube Rotameter
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 determines the flowrate.

Digital Variable Area Flow 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. This got an inbuilt two wire transmitter just provide 24 VDC. And take 4 – 20 mA signal.

Benefits of CRYSTAL Variable Area Flowmeters
• Local 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.
