What is a clamp-on ultrasonic flowmeter?

Benefits, applications, and technical notes for PECTRONIC clamp-on ultrasonic flowmeters for non-invasive flow measurement.

Clamp-on ultrasonic flowmeters measure flow from outside the pipe — no contact with the fluid and no pipe cutting. That reduces installation cost and keeps operating lines running.

PECTRONIC clamp-on models cover a wide diameter range (including DN 25–1600) and can monitor related temperature as well, with roughly 1% accuracy suitable for many industrial duties.

Typical uses include water networks, treatment plants, thermal energy monitoring, and process lines where shutdown is expensive. Compared with in-line meters, maintenance is simpler and joint-leak risk is lower.

  • Install without stopping flow or welding the pipe
  • Useful for temporary checks, verification, and permanent metering
  • Iranian manufacturing with PECTRONIC warranty and support
