The relative flow direction is shown on the Calibration Detail label affixed to the pipe fitting. 6.2.2.4
Fluid Flow
Direction
Each of the flow directions (A to B and B to A) have a Scaling Factor and either a positive or
negative Zero Factor associated with it. The correct factors are shown on the Calibration
Detail label affixed to the ultrasonic flow sensor pipe fitting.
These are factory calibration factors that should not be changed without first
contacting the factory for technical assistance.

Each pipe fitting has a specific Pipe Outside Dia., Pipe Wall Thick., Pipe Material and Pipe
SOS (Speed Of Sound) associated with it. The correct factors are shown on the Calibration
Detail label affixed to the ultrasonic flow sensor pipe fitting.
These are factory calibration factors that should not be changed without first

The sound transducers are located in the S4 pipe fitting. They are carefully positioned at the
factory for use with water at 68 degrees F which has a SOS (Speed Of Sound) of 1481
meters per second. (see page 28 for water SOS chart). The transducer placement cannot be
adjusted in the field. As the fluid’s sound speed moves away from the target Fluid SOS,
measurements become more difficult. If the speed that sound travels through the fluid is very
different than that of water, the meter will not function. The acceptable SOS range is from
1,400 to 1,600 m/sec.
The meter will display the SOS of the fluid being measured in the upper right hand corner of
the display.
Successful measurements are possible with fluids other than water provided the fluid’s SOS
is within the acceptable range and there are not too many particles or other sound blocking or
reflecting contaminants in the fluid which can inhibit the sound beam.
The target Fluid SOS value can be adjusted to maximize the meter’s ability to measure the
fluid. The chart below provides the sound speeds of a number of chemicals of specific
concentrations at specific temperatures. Diluted chemicals will have a different sound speed.
Select Custom from the Fluid Type menu, then input the SOS fluid in the Fluid SOS menu.
