TRANSMITTER SETUP
10.1 Transmitter Menus
The following pages present the steps necessary to setup and operate
the SONARtrac
TM
VF & GVF-100 system.
Whenever a transmitter front panel entry is made, the transmitter will
re-start and output to the plant control or data logging system will be
interrupted. It is recommended that the process control room be
alerted prior to accessing the transmitter front panel.
CAUTION
Loss of transmitter output signal may occur when accessing
transmitter front panel keys. Contact process control room and
advise them the transmitter may be off line.
10.1.1 Basic Config Menu
These inputs must be made when installing a system.
•
Sensor Serial #
The 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.
•
Pipe Size
Input based on the pipe the system is installed on. Input can be
based on ‘ID/Wall (pipe inner diameter / wall thickness)’, or calculated
by the transmitter from the inputs of ‘OD/Wall’ (pipe outer diameter /
wall thickness) or ‘Size/Sched’ (pipe size / schedule).
•
Pipe Material
Used to input the modulus of the process pipe material in units of kPa.
Menu selections for steel, stainless steel, PVC and custom values for
other pipe materials are selectable from the menu.
•
Fluid Properties
‘Specific Gravity’ - Input is default to 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.
‘SOS’ – Used to input the nominal sound speed of the process fluid.
Water at 25ºC and 14.7 psia is the default; custom values can be
input. Refer to Appendix F for additional values for water at different
temperatures and pressures.
