in the site name, you can type these characters directly from the keypad.
To Save or Rename a Site Setup:
To access the first character position
To select a character then to highlight to next character position.
To select the second character . Repeat this process to select all the

2.2 THE PIPE DATA MENU
This menu becomes available after picking a Meter Type, Measurement Channel and Mea-
surement Technology. We recommend that you edit the Pipe Data immediately after creating
a new Site Setup.
The Pipe Data menu allows you to define the application’s pipe parameters. Select a pipe from
one of the meter’s stored pipe tables (see menu structure below); or input the pipe size and
description manually. Manual entries include Pipe Material, Outer Diameter (OD) and pipe
Wall Thickness. Liner Material and Liner Thickness entries are included to support pipes
with liners. The meter requires the pipe outer diameter (OD) and wall thickness to operate.
You must define these parameters to complete the installation.
The pipe table includes descriptions for over sixty standard pipes plus any user-entered pipes
(see Meter Facilities). To use these presets, first pick a Pipe Class (e.g., ASA Stainless Steel),
then pick a pipe size within that class (e.g., 4SS10). When you select a particular pipe class/
size, the relevant pipe parameters appear in the Pipe Data menu cells. If a given pipe class/
size does not match your application exactly you can still edit each individual parameter to
fine-tune your selection. In addition, the Meter Facilities section of the Installation Menu
provides a pipe table editor that allows you to customize any or all of the stored pipe tables.
NOTE: If you edit the pipe parameters after the system is operating, you will have to
repeat the transducer install procedure.

This 1010 operating system includes routines that will compensate the measured raw flow
rate for dynamic changes in the pipe dimensions, caused by variations in line temperature
and pressure supplied to the flow meter. To account for variations in pipe material, two data
entry items (Thermal Expansion Coefficient and Modulus of Elasticity) are provided in the
1010 Pipe Data menu screen (see sample menu screen on next page).
The equation used to automatically compute the change in pipe inside diameter is:
Where:
d

= inside diameter of pipe at STP
d

= inside diameter of pipe after temperature and pressure change.
