A-16 Entering Special Transducer Pipe Parameters
Entering Parameters for Wetted Transducers (cont.)
If you have enabled the tracking windows,you may choose one of
the following:
• Water, 0-100° C
• Water, 0-260° C
• Oil
• Other — Enter sound speed (c3) limits
Use the [←] [→] keys to view all the available options. Then use
the appropriate feature key to make a choice. Depending on the
fluid type you choose, the TransPort may ask you for additional
information such as fluid temperature or sound speed.
11W. Entering the Reynolds Correction Factor
The Reynolds Correction Factor is a number based on the
viscosity 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 in 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.
• Press [F1] to disable the Reynolds Factor.
• Press [F2] to enable it. Then use the numeric keys to enter the
Kinematic Viscosity, and press [ENT].
12W. 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 correction factor should be
set to 1.00. Otherwise the typical factor is between .50 and 2.00.
Use the numeric keys to enter a value and press [ENT].
