2.2.3 HOW TO ENTER THE PIPE OD (in. or mm.)

Use this menu cell to edit the pipe outer diameter. Be aware that you will not be able to complete the

transducer installation successfully unless this information is accurate. In addition, if you change this

parameter on a previously installed site, you will have to repeat the transducer installation. Note: Use

actual pipe dimensions, not ASA code or any other standard. The English/Metric selection in the Meter

Facilities menu determines whether these dimensions are in inches or millimeters.

To enter the Pipe OD:

To enable numeric entry press

Use the keypad’s numeric keys to type the exact outer diameter of the pipe in inches or millime-

ters.

2.2.4 HOW TO SELECT A PIPE MATERIAL

The pipe material selection affects flow calibration to a small degree. It also influences the meter-

generated transducer size and spacing recommendations. Select a substitute material if you do not

find the material of your pipe in the pipe table. You can edit each pipe parameter to achieve a closer

match. If you change any pipe parameters, after running the Transducer Install procedure, you may

have to re-space the transducers. The Pipe Material option list provides a selection of common pipe

materials. The default pipe material is Steel. Press <Down Arrow> to accept the default setting for this

menu cell.

2.2.5 HOW TO ENTER THE WALL THICKNESS

The wall thickness of the pipe is one of the required parameters. The flow computer needs this data to

generate accurate transducer size and spacing data recommendations. Selecting a pipe class/size

inserts a wall thickness value. If this data is inaccurate, then use this menu cell to set the pipe’s wall

thickness (in English or Metric data units).
