Dwyer Instruments HFB-6-150 | In-line flow monitor | 2" female NPT | 20-150 GPM (76-568 LPM) water
Ruggedly built and perfect for direct measurement of a variety of suitable gases, oil- or water-based liquids, are the Model HFB-6-150 In-Line Flow Monitors. Variable area flow measurement and a floating orifice disk serve as the foundation for the design of this series. The orifice disk and ring-shaped magnet, which are mounted on a tapered central shaft, are forced to move linearly by flowing media. A ring on the magnet follower, which is external to the flow tube and driven by the transfer magnet, shows the flow rate on the direct reading scale.

- Accurate performance with fluid viscosities up to 500 SSU is made possible by this special design.
- A sealed metal tube casing encloses all interior wetted sections, providing an almost maintenance-free machine.
- Greater application flexibility due to the lack of a straight piping requirement for the inlet or outlet and the ability to be installed in any orientation.
- High pressure and temperature ratings are possible due to the robust construction, which prolongs operation life.
