Model UFM Compact Ultrasonic Flowmeter is a low cost clamp-on, ultrasonic flowmeter.

The Model UFM implements the transit-time difference to measure flow rates in pipes non-invasively. It is a compact and lightweight design, featuring an easily installed, all in one clamp-on unit.

This unit can measure velocity and flow in pipes with outside diameters ranging from 0.98 to 4.62" (24.89 to 117.35 mm).

The screen offers easy to read text with a convenient backlight for visual comfort.

This model comes with a volume pulse and 4 to 20 mA flow rate output.
Features
  • Non-invasive pipe measurement
  • Simple installation with all necessary components included such as converter, sensor, cables and mounting accessories
  • Compact and lightweight design, featuring an easily installed, all in one clamp-on unit intended for homogeneous liquids that contain no air
  • Screen offers easy to read text displaying both flow rate and total with a convenient backlight for visual comfort
  • Kit Includes:
    • Converter w/ adjustable guiderail
    • Set of 1.81 to 2.75" (46 to 70 mm)clamps
    • Set of 2 to 5" (51 to 127 mm) clamps
    • Set of small pipe adaptor circle clamps
    • Set of small pipe adaptor V clamps
    • Ultrasonic coupling grease
