Need the latest portable model with a 360° rotatable display and wider pipe range (up to DN5000)? See the YF-P2 Portable Ultrasonic Flow Meter.
The YF-P1 Portable Ultrasonic Flow Meter is a handheld, battery-powered transit-time flow meter designed for temporary measurement, field surveys, pump testing, balancing and spot-checks. Clamp the transducers onto the outside of the pipe — no cutting, no downtime, no pressure loss. A built-in rechargeable lithium battery provides up to 16 hours of continuous operation, and the rugged die-cast aluminium housing is built for site work.
It works on carbon steel, stainless steel, PVC, copper and lined pipes from DN25 to DN2000 (1″–80″), measuring water, seawater, chemicals and other clean, single-phase liquids.

Frequently Asked Questions
What is the YF-P1 portable ultrasonic flow meter?
The YF-P1 is a handheld, battery-powered clamp-on ultrasonic flow meter for temporary and field flow measurement. Transducers clamp onto the outside of the pipe, so there is no pipe cutting, no process shutdown and no contact with the liquid.
How long does the YF-P1 battery last?
The built-in rechargeable lithium battery supports up to 16 hours of continuous use, which is enough for a full day of spot checks, pump testing or commissioning work without mains power.
What pipe sizes and materials does it support?
It measures pipes from DN25 to DN2000 (1″–80″), including carbon steel, stainless steel, PVC, copper and lined pipes, using V, Z and N/W mounting methods.
How accurate is the YF-P1 and what outputs does it have?
Accuracy is ±1.0% of reading with 0.2% repeatability, on bidirectional flow from 0 to ±12 m/s. It provides a 4–20 mA analog output plus pulse/OCT (0–9999 Hz), with a 2.8″ TFT display and 20-key keypad.
