Entering Special Transducer Pipe Parameters A-5

December 2003

Entering Parameters for Clamp-On Transducers

(cont.)

7C. Entering the Pipe Material

Enter the pipe material. Since clamp-on transducers send their

ultrasonic signals through the pipe wall, the sound speed of the

pipe material must be factored in to obtain an accurate flow

measurement. Clamp-on transducers are applicable on a variety

of pipe materials, only a few of which are among the options for

this prompt. If your pipe material is not among the options, select

“OTHER” and enter the sound speed of your pipe material from

the tables in Sound Speeds and Pipe Size Data (914-004).

Use the following steps to enter the pipe material:

1. Use the [←] [→] keys to view all the pipe material categories.

See Table A-1 for the available categories.

2. Press the appropriate feature key to choose the desired

category.

3. Depending on the pipe material choice, the TransPort asks you

to choose a specific material. Use the arrow keys to view all

the pipe materials. See Table A-1 for available options.

Note: If you choose brass, copper, or aluminum, skip to the next

step, Entering the Outside Diameter of the Pipe.

4. Press the appropriate feature key to choose the desired

material.
