Piping Congurations and Transducer Positioning
Figure 2 shows the number of pipe diameters required downstream and upstream of the transducers for various
piping configurations.

Figure 2: Piping configuration and transducer positioning
The system will provide repeatable measurements on piping systems that do not meet these pipe diameter requirements, but
the accuracy of the readings may be influenced.
Mounting Conguration
The mounting configuration for these transducers is V-Mount, where the sound traverses the pipe twice. V-Mount is a
compromise between travel time and signal strength.
