Series HF In-Line Flow Monitor

Brand: Dwyer Instruments, LLC

Favorite

The SERIES HF In-Line Flow Monitors are ruggedly constructed and ideal for direct measurement for a range of compatible gases, oil or water based liquids. 

This Series is designed based on a floating orifice disk and variable area flow measurement. Flowing media forces linear motion of the orifice disk and a ring shaped magnet which ride on a tapered center shaft.

The transfer magnet drives a clearly visible magnet follower located outside the flow tube, and a ring on the magnet follower indicates flow rate on the direct reading scale.
Features
  • This unique design allows accurate performance with fluid viscosities up to 500 SSU
  • All internal wetted parts are contained inside a sealed metal tubular casing assuring a virtually maintenance-free unit
  • Increased application versatility with no inlet or outlet straight plumbing requirement and can be mounted horizontally, vertically, or inverted
  • Rugged construction allows for high pressure and temperature rating for long operation life
