FLOWTECH ss Tube Variable Area Flow Meters (Rota meters) are intended for general in line and By-Pass metering applications (i.e. for Gas & Liquid) where operating conditions are with the limitations of Glass metering tubes. These are the principle of Variable Area. The float moves freely up and down taperedborosilicate glass with fluid flow from bottom to top. The float takes up aposition where buoyancy forces and the float weight are balanced in proportionto flow rate. The Vertical position of the float as indicated by scale is themeasure of the instantaneous flow rate.
