Series UFM2 Compact Ultrasonic Flowmeters

Cost Effective, Compact and Adjustable Design, Non-Invasive

The Series UFM2 Compact Ultrasonic Flowmeters are economical, clamp-on, ultrasonic flowmeters. The UFM2 implements the transit-time difference to measure flow rates in pipes and can measure velocity and flow in pipes with outside diameters ranging from 3/4 to 7" (25 to 180 mm). This model comes with a volume pulse and 4-20 mA flow rate output.

• Converter with adjustable guide rail
• Set of pipe clamps (model dependent)
• Set of small pipe adapter circle clamps
• Set of small pipe adapter V clamps
• Ultrasonic coupling grease

Product Applications

  • Flow measurement for heat metering
  • Metering and monitoring in: Chilled water, Potable water, Process water
