9C. Entering the Reynolds Correction Factor
The Reynolds Correction Factor is a number based on the
Kinematic Viscosity and flow rate of the fluid. Generally, it
should only be enabled when using transducers mounted in a
diametrical path (such as clamp-on or tilted diameter).
If you enable the Reynolds Correction Factor, you will also need
to enter the Kinematic Viscosity of the fluid (units are ft
2
/sec or
m
2
/sec depending on the units selected). Refer to Sound Speeds
and Pipe Size Data for the Kinematic Viscosity of your fluid.
a. Press:
• [F1] to disable the Reynolds Factor.
• [F2] to enable it.
b. Enter the Kinematic Viscosity. The default value is for
water at 20°C. Press [ENT].
10C. Entering the Calibration Factor
The Calibration Factor is used as a reference for the flowmeter
electronics to ensure accurate readings. Generally, if you enable
the Reynolds Correction Factor, the calibration factor should be
set to 1.00. Otherwise the typical factor is between .90 and 1.00.
Use the numeric keys to enter a value and press [ENT].
11C. Entering the Number of Traverses
Enter the number of times the ultrasonic signal traverses the pipe
(see the Transducer Installation Guide for more details).
Use the [←] [→] keys to view all the options and press the
appropriate feature key to respond.
