PTFM 1.0 Portable Flowmeter

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.

User-Friendly Operating System

Calibration is easy with the onscreen menu system. Just enter the pipe diameter, wall thickness and pipe material. The PTFM 1.0 is powered by an internal, rechargeable NiMH battery or can be operated continuously with AC power adapter. Each PTFM 1.0 includes a watertight carry case, transducer set, cables and mounting clamps.

Built-in Data Logger with Windows Software Included

Set up the 300,000 point data logger to store time and date-stamped flow readings from 10 second to 5 minute intervals. View the convenient on-screen 'Flow Report' where total, minimum, maximum and average flow rates are stored in a 24 hour daily summary.

Transfer flow logs to your PC or laptop through the PTFM 1.0's USB output. Greyline Logger software (included) displays data in both graph and table formats with one-click export to Microsoft Excel®, images or CSV files for use in other programs.
