Entering Special Transducer Pipe Parameters A-13
December 2003
Entering Parameters for Wetted Transducers (cont.)
4W. Entering the Time Delay
Tw, the time delay, is actually the time the transducer signal
spends travelling through the transducer and cable. This time
must be taken into consideration since the TransPort calculates
the flow rate by subtracting the time of the upstream and
downstream signals. Therefore, the time delay must be subtracted
out for an accurate measurement.
Use the numeric keys to enter the time delay (in microseconds).
The time delay is supplied by GE Panametrics on a sheet of paper
inside the transducer case. Press [ENT].
5W. Entering the Outside Diameter of the Pipe
If you do not know the outside diameter of your pipe, you can
measure it, or Sound Speeds and Pipe Size Data contains some
standard pipe sizes with their corresponding outside diameters.
To enter the outside diameter:
1. Press the appropriate feature key to select the units.
2. Use the numeric keys to enter the outside diameter. Press
[ENT].
