Portable Ultrasonic Flowmeter

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.
