Glass Tube Rotameter, Size : 15 NB to 80 NB

Listing ID #3741960

Glass Tube Rotameter is basically a Variable Area. Principle The differential pressure across the annulus area is constant and the flow rate is measured as a function of the annulus area. This area is displayed as the position of a “Float”. These rota meters are useful for measuring flow of air, common gases, water, alkalies, oil & organic chemicals. Our offered range of glass meters is appreciated for its features such as high tensile strength, dimensional accuracy and compact design.Glass Tube Rotameter Area Flow Meters (Rotameters) 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 tapered borosilicate glass 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.
