December 2003

Entering Parameters for Clamp-On Transducers

If you are using Rayleigh or Shear wave clamp-on transducers,

you will get the following prompts:

• Frequency

• Tw (time delay)

• Wedge Angle

• Wedge Sound Speed

• Pipe Material

• Pipe Sound Speed

• Pipe O.D. (pipe outside diameter)

• Pipe Wall Thickness

• Lining (material and thickness)

• Tracking Windows

• Fluid Type

• Reynolds Correction Factor

• Calibration Factor

• Number of Traverses

• Transducer Spacing

Some of the above parameters are supplied by GE Panametrics on

a sheet of paper inside the transducer case. Refer to this sheet

when instructed.

3C. Entering the Frequency

Enter the transducer frequency. The TransPort needs to know the

frequency in order to transmit a voltage at a rate to which the

transducer can respond.

Use the appropriate feature key to select one of the following

choices:

• 500 k

• 1 MHz

• 2 MHz

• 4 MHz
