The Series PUB & PUF Portable Ultrasonic Flowmeter Kits utilize the transit-time difference for measuring ow rates in pipes non-invasively. Units offer ow rate local

display with analog and pulsed outputs. The Series PUF offers the same features plus data logging capability.

BENEFITS/FEATURES

• Non-invasive pipe measurement

• Compact and lightweight

• Incorporate the latest electronics and signal processing technologies realizing high

performance and easy operation

• Ideal for on-the-go ow monitoring, capable of 20 hours continuous operation with

Flow Transmitters,
