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.
The mentioned prices are approx price & it may vary as per your requirement because it requires customization in product.
