Portable Ultrasonic Flowmeter

for Troubleshooting, Calibration Checks

and Balancing Flow

Measures Flow Outsidefrom the of a Pipe

The PTFM 1.0 Portable Transit Time Flow Meter works by measuring the “transit time” or

“time of flight” for ultrasonic sound pulses transmitted from one transducer to another.

transit time in the direction of flow is faster than the transit time against the flow. By
comparing these differences with precision timing circuits, the PTFM 1.0 is able to
accurately calculate the flow rate

Choice of V, Z or W mounting method depends on the application and pipe diameter. V­Mount is the most common method while Z-Mount is used for larger pipes or weak signal
applications and W-Mount for smaller pipes.

Mount the ltrasonic transducers on the outside of metal oru
plastic pipes 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. Avoid pipes made with porous materials
(e.g. wood or concrete) or with loose insertion liners.

Measures in Full PipesClean Liquids

The PTFM 1.0 Portable Transit Time Flow Meter is designed clean, non-aeratedto measure
liquids .like water, chemicals and oils with less than 2% solids or bubbles The ultrasonic
transducers can be mounted on vertical or horizontal pipes.

Simple Menu System for Start-up and CalibrationEasy

Calibration and start-up can be done in a few minutes. Use the built-in 5-button keypad to
enter the pipe material and OD, wall thickness and fluid type. The PTFM 1.0 will display the
correct transducer separation distance. Secure the stainless steel pipe clamps and align the
mounting brackets on the outside of the pipe. Put coupling compound ( ) on theincluded
transducer faces insert them into the mounting brackets The PTFM 1.0 will immediatelyand .
begin to display, transmit and totalize flow.

The PTFM 1.0 Portable
Transit Time Flowmeter
is ideal to measure flow
rate of clean, non-aerated
fluids in full pipes. Works
best on fluids that have
less than 2% particulate
or gas bubbles.

Easy to Install

The PTFM 1.0 Portable Transit
Time Flow Meter tois designed
measure in fullclean liquids
pipes It. works by injecting sound
through the pipe wall and into the
flowing liquid.

The battery-powered flow meter,
transducers, mounting clamps and
accessories are supplied with a
rugged watertight carrying case. Use it
for troubleshooting, flow studies and for
testing calibration of inline flow meters.

The PTFM 1.0 works on metal and plastic
pipes and measures forward or reverse
flow. A built-in data logger and Windows
software is included.

Easy to Calibrate

Use the 5-button keypad and menu system to set up the flowmeter by entering the
pipe material, diameter and wall thickness. The PTFM 1.0 calculates the transducer
separation distance and mounting method automatically.
