Recommended for fluids like water, glycol, oils and chemicals. Use it for calibrations, troubleshooting, flow surveys and as a temporary transmitter to replace inline flowmeters.

The PTFM 1.0 ultrasonic transducers strap-on the outside of pipes from ½" to 48" (12 to 1200 mm) diameter. The ultrasonic signal works through common pipe materials including carbon steel, stainless steel, ductile iron, cast iron, PVC, PVDF, fiberglass, copper, brass, aluminum and pipes with bonded liners including epoxy, rubber and Teflon. Transducers can be mounted without shutting down flow and there is no obstruction or pressure drop. It measures and totalizes forward and reverse flow.

The 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 travelling upstream and downstream.
