SERIES PUB & PUF

PORTABLE ULTRASONIC FLOWMETER KIT

FLOW

Portable, Non-Invasive and Data Logging Option

PUB

PUF

The SERIES PUB & PUF Portable Ultrasonic Flowmeter Sets 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.
