Glass Tube Rotameter

Description:

Glass Tube Variable 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.

Design Features:

1. Dowel Pin, side plate construction

2. Detachable flow scales

3. Externally adjustable packing glands

4. Connections can be rotated 360 degree at 90 degree

5. Laminated safety glass shielding

Performance:

Enclosure : IP 55 OR IP 65 on request.
