GLASS TUBE ROTAMETER

Product catalog summary

Introduction
FLOWTECH Glass Tube Variable Area Flow Meters, also known as Rotameters, are designed for inline and by-pass metering applications for gases and liquids. They operate on the principle of variable area, where a float moves within a tapered borosilicate glass tube, indicating flow rate based on its vertical position.

Specifications
- Accuracy: ± 2% F.S.D.
- Temperature Ratings: Up to 121º C for gases and 93º C for liquids.
- Repeatability: 0.5%
- Connections: Flanged, Screwed, Tri Clover Joint, or Hose Nipple.
- Rangeability: 10:1
- Enclosure: IP 55 or IP 65 on request.
- Scale Length: 180-200 mm.

Materials
- Tube: Borosilicate Glass
- Float: SS 316, PTFE, Aluminum, P.P.
- Pickings: Neoprene, PTFE, Silicon, Viton
- Frame & Cover: M.S. or SS
- End Fitting: Various materials including M.S., C.S., SS304, SS316, and others on request.

Flow Formula
The flow rate (Q) is determined using the formula involving volumetric flow rate, float volume, flow coefficient, pressure receiving area of the float, fluid passing area, float density, gravimetric acceleration, and fluid density.

Capacity Table
The document provides a detailed capacity table for different meter sizes, indicating the minimum and maximum flow rates for water and air, along with the pressure drop in mm WC.

Overall Dimensions
Dimensions for various models and meter sizes are provided, detailing measurements such as height and width.

Additional Information
FLOWTECH Measuring Instruments Pvt. Ltd. is an ISO 9001:2008 certified company, exporting to multiple countries and offering local dealership in various Indian cities. They also provide online calibration of flowmeters on request.

Note
Specifications are subject to change without notice.

DESCRIPTION “FLOWTECH” 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....
