USER INTERFACE
SOFTWARE SCREENS This section illustrates each major Model 3095FT User Interface
screen, and provides information on using the screen.
Configuration Screens The configuration screens define a configuration that can be sent to a
transmitter (Send Xmtr), and/or saved to a file (Save Config File).

Flow Parameters
The flow parameters screen (Figure 4-5) should be completed first
whenever preparing a Model 3095FT configuration. This screen
defines:
Software Tag
The software tag uniquely identifies the transmitter. This tag is also
used to identify audit trail data retrieved from the transmitter.
Meter Tube Bore @ 68F (in)
Identifies the diameter of the meter tube bore.
Meter Tube Matl
Allows selecting one of five meter tube materials: carbon steel, SST 304,
SST 316, Hastelloy C, and Monel.
Orifice Bore @ 68F (in)
Identifies the diameter of the orifice bore.
NOTE
The Orifice Bore/Meter Tube Bore ratio (
β
) should be within the
following range:
Flange Tap: 0.1
≤ β ≤
0.75 Pipe Tap: 0.2
≤ β ≤
0.67
Orifice Plate Matl
Allows selecting one of five orifice plate materials: carbon steel, SST
304, SST 316, Hastelloy C, and Monel.
Orifice Tap Type
Allows selecting either flange or pipe taps.
