Flow Stream
Requirements
The Sonic-Pro’s sound wave beam is only affected by fluid that actually passes through
the beam and therefore, the meter will not measure accurately if the fluid velocity is not
consistent across the entire pipe diameter. Flow disturbances such as pumps, elbows,
tees, and valves in the flow stream can cause swirl patterns and vortices that will affect
the measurement. Install the transducers on a straight run of pipe
as far as possible
from any disturbances. The distance required for accuracy will depend on the type of
disturbance.
!
The Sonic-Pro can be used with a large number of pipe materials and sizes. However,
the successful installation will take into account not only the pipe diameter, but also the
pipe material, the wall thickness and the surface finish of the inside and outside walls of
the pipe. Follow these piping guidelines to ensure a successful installation:
!
Do not attempt to measure very low flow velocities in the Doppler mode. In some cases,
the particles in the flow stream can fall out of suspension resulting in error or failure.
!
The outside surface of the pipe must be clean and smooth. Insulation, coatings, rust
and other surface imperfections should be removed before installing the transducers.
!
The inside surface of the pipe must be clean and smooth to properly reflect the sound
wave.
