GLASS TUBE ROTAMETER

ROTAMETER
OPERATING PRINCIPLE
Glass Tube Rotameter is basically a Variable Area Flow Meter.

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”.

STANDARD FEATURES :

Various Material of Construction   Easy to Maintain and Replace
Line Size from 15 NB to 80 NB   Suitable for on Line Installation
Heavy Duty Design with Maximum Visibility   Measuring Span : 1:10
Ranges between 2.0 LPH to 25000 LPH   Glass : Borosilicate
Two Tone Powder Coated Excellent Finish   Linear Scale
No Threads in Body, Avoids Corrosion   Slip on Flange - facilitates change in line of sight
Face-To-Face Distance : 500 mm   Accuracy : +/- 2% of Full Scale
Single Piece (jointless) PTFE / PP claded end connections
Float is provided with PTFE Indicating Ring which minimizes breakage of Glass Tube
