Origin of Metal Tube Rotameter
Digital Meter: High sensitive sensor for magnetic field detection is there to find out the inner float magnetic field. It enables us to display the digital read out. As it operates on battery, this flow-meter does not involve any electrical connection. It has built-in two wire transmitter that provides 24 VDC and take 4-20 mA signal.

Advantages of  Digital Variable Area Flow Meters:
 

Local indication without the auxiliary power requirement

Minimal loss of pressure

Easy to read

Suited for low flow (8LPH)

Accurate measuring, even at higher flow (150 m3/hr)

Assembly with no movement, reducing the maintenance

Default built-in transmitter of 4 to 20 mA, Loop-powered

It operates on the principle of variable area; the fluid in the metal tube raises the float in the taper tube increasing the area of passage of fluid. 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. 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 CVG'S variable area flow meters:-

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 (10 lph)default inbuilt transmitter of 4 – 20 ma (loop powered). No movement assembly reducing the maintenance.
