Description
Looking for a battery-powered handheld unit? See also the YF-P1 Portable Ultrasonic Flow Meter.
The YF-P2 is a high-accuracy portable clamp-on ultrasonic flow meter for temporary measurement, field surveys, pump testing, HVAC balancing and flow verification. Clamp the transducers onto the outside of the pipe — no cutting, no downtime, no pressure loss — and carry the unit from site to site in its case.
It delivers ±0.5% accuracy over a wide 0.1–12.0 m/s velocity range and works on pipes from DN25 to DN5000 (1″–200″) using V and N mounting methods. The 3.5″ 480×320 IPS display rotates 360° for easy reading in any position, and outputs include 4–20 mA, RS485 Modbus RTU and OCT pulse/alarm.
