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

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.

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.
