FLOWTECHÃÂÂ¢ÃÂÂÃÂÂ Acrylic Body Tube Variable Area Flow Meters (Rotameters) are intended for general in line metering applications (i.e. for Gas & Liquid) where operating conditions are with the limitations of Acrylic Body metering tubes. These are the principle of Variable Area. The float moves freely up and down tapered Acrylic body Tube with fluid flow from bottom to top. The float takes up a position where buoyancy forces and the float weight are balanced in proportion to flow rate. The Vertical position of the float as indicated by scale is the measure of the instantaneous flow rate. Accuracy : +/- 2% F.S.D. Temperature Ratings : Maximum Operating Temperature rating is 50 o C Repeatability : 0.5 % Connections : Flanged OR Screwed OR Triclover Joint OR Hose Nipple Rangebility : 10:1 Scale length : 180-200 mm Pressure Ratings : Meter Size Max.
