Backed by our immense knowledge and years of experience in this domain, we are able to manufacture, supply and export top grade Glass Tube Variable Area Flow Meters. These flow meters are mainly used to measure flow rate of various fluids in different industries. The offered flow meters have a glass tube with float (is a cone shaped material) that rises and drops on the passage of fluid. The float in these tubes are generally made from material that is denser than the fluid. These glass tube variable area flow meters are perfect for measuring the flow of liquid and gas in places where viewing process in of utmost importance.
