8.2 Basic Config Menu
These inputs must be made when installing a system.
8.2.1 Sensor Serial #
A Sensor Serial Number assigned to each sensor band. This identifier
is found on the sensor band, and on the label previously attached to
the sensor cover access panel and the transmitter.
8.2.2 Pipe Size
The Pipe Size input based on the pipe the system is installed on.
Input can be ‘ID/Wall (pipe inner diameter / wall thickness)’, ‘OD/Wall’
(pipe outer diameter / wall thickness) or ‘Size/Sched’ (pipe size /
schedule). User selectable units of inch or millimeter are available.
8.2.3 Pipe Material (Systems with GVF)
Pipe Material is used to input the modulus of the process pipe material
in units of kilo Pascal (kPa). Menu selections for steel, stainless steel,
PVC and custom values for other pipe materials are selectable from
the menu.
8.2.4 Fluid Properties
8.2.4.1 Specific Gravity
The Specific Gravity default is water at 25 ºC and 14.7 psia. Refer to
Appendix E for unit conversions and Appendix F for other
temperatures and pressures. Custom user selectable values can also
be set.
8.2.4.2 SOS
– (Systems with GVF)
Speed Of Sound (SOS) is used to input the nominal sound speed of
the process fluid. Default is water at 25 ºC and 14.7 psia in units of
feet per second; custom values can be input. Refer to Appendix F for
additional values for water at different temperatures and pressures.
8.2.4.3 Viscosity (Systems with Flow)
The Viscosity default is water at 25 ºC and 14.7 psia in units of
Pascal-second. Refer to Appendix E for unit conversions and
Appendix F for other temperatures and pressures. Custom user
selectable values can also be set.
8.2.5 Pressure (Systems with GVF)
The Pressure input is an important parameter for accurate GVF
measurement. If the process pressure is constant, input the normal
process operating pressure into the transmitter in units of PSIg, Barg
or kPag.
