HFS-2-10

Series SSM All Metal Flowmeters

Series HF In-Line Flow Monitors

For Air, Water or Caustic Fluids, ±2% FS, Unrestricted Mounting, High Temperature and Pressure Options

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.

Note: If you require a calibration certificate with your flowmeter, please contact customer service to place your order.
