Principle Of Operation

The Rotameter’s operation is based on the variable area principle: fluid flow raises a float in a tapered tube, increasing the area for passage of the fluid.

The greater the flow, the higher the float is raised. The height of the float is directly proportional to the flow rate.

The float reaches the stable position in the tube when the upward force entered by the flowing liquid equals to the downwards gravitational force entered by the weight of float.


  • Complete flow range from 10 LPH up to 60000 LPH. Available from 15NB end connection to 65NB end connections.

  • Over 15 different models to suit all ranges

  • Available in on-line (Threaded/ Flanged) connection. Tri-Chlor and Panel Mounted (with elbow BSP male threaded) connections for all ranges

  • Single Piece, Injection Moulded, Polycarbonate Body

  • Each Rotameter is Hydro Tested at 8 kg/cm² pressure

  • Tamper & Sunlight Proof Graduation Sticker

  • Enhanced Meter Readability Using Precision Textured Body

  • SS 316 Rod & Float for Rust-Free Usage

  • Each Rotameter is Factory Calibrated

  • Each Float is Buffed for Accuracy & Repeatability

  • Negligible Pressure Drop
