Greyline PTFM 1.0 Portable Ultrasonic Transit Time Flow Meter p/n# PTFM 1.0
The Greyline PTFM 1.0 Portable Transit Time Flow Meter operates by measuring the “transit time” or “time of flight” for ultrasonic sound pulses transmitted from one transducer to another. Depending on the mounting configuration the signal may cross the pipe once, twice, or four times. To measure flow the transit time is compared between ultrasonic signals traveling upstream and downstream. Use it for calibrations, troubleshooting, flow surveys, and as a temporary transmitter to replace inline flowmeters.
Ultrasonic transducers clamp-on the outside of pipes from 50 mm to 1200 mm (2 in to 48 in) diameter. Transducers can be mounted without shutting down flow and there is no obstruction or pressure drop. It measures and totalizes forward and reverse flow.
