Entering Parameters for Clamp-On Transducers

(cont.)

3C.Entering 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:

a. Use the [←] [→] keys to view all the pipe material choices.

See Table 3-3 on the next page or the available materials.

b. Press the appropriate feature key to choose the desired

materials.

c. Depending on the pipe material choice, the TransPort may

ask for further information. See Table 3-3 on the next page

for the various pipe materials available. If required, press

the appropriate feature key to choose the desired material.
