Transport PT868-R from Panametrics is a portable flowmeter available with transflection mode and transit-time mode.

Users can now measure fluids from ultra-pure water to slurries, and pipe-wall thickness using the optional thickness transducer, with one ultrasonic instrument.

The device can also measure energy flow using inputs from temperature transducers.

It uses high-speed digital signal processing techniques, including patented acoustic signal coding and correlation to yield high signal-to-noise ratios in the most demanding applications.
