4.2 Standard Commissioning Procedure
Settings for calibration
see Section 4.3
This Section describes all the settings that are essential to ensure that the device functions
correctly. These include the settings for installation data (measuring path, installation
angle), and output variables (standard analog output, response times and check cycle).
Note: Until the installation data has been fully entered, the error message ‘‘Error Parameter” is
output.
To change the parameters, the following steps are required: Enter the password for user
level 1 (see Fig. 4.7). Select the type FLOWSIC100 on the page "Network Scan Assistant"
and move it into the "Project Tree" window by double-click or drag-and-drop. Switch the
FLOWSIC100 to Maintenance Mode: Go to the subpage ‘‘Maintenance / Maintenance
Status”, activate the check box "Sensor Maintenance" and click the ‘‘Set Status” button
(see Fig. 4.9). The active Maintenance Mode is indicated by a glowing status indicator in this
subpage and on the ‘‘Diagnosis / Sensor Values” subpage..

4.2.1 Entering the Application Data (Project Tree FLOWSIC100 Sensor)
Before a measurement can be started, you have to select the unit system (metric or imperial
units) and enter the application parameters (measuring distance, installation angle, cross-
sectional area). Select the type FLOWSIC100 in the menu "Device Catalog / Available
Devices" and go to the "Configuration / Application Parameters" subpage in the "Project
Tree" window (see Fig. 4.10). The settings are uploaded to the FLOWSIC100 after switching
from "Maintenance" to "Measurement".
Note: The application parameter settings are converted automatically if you change the unit
system.
Application parameters:
Path length Distance between the transducers (L in Fig. 4.11)
Installation
angle
Angle between the measurement axis and main direction of the gas flow (α in Fig.
4.11)
Area of duct
(required to
calculate the
volumetric flow)
Area between the internal duct walls between the two sender/receiver units
perpendicular to the flow direction; (A in Fig. 4.11)
If the cross-sectional area changes in the vicinity of the measurement location,
enter the mean value of the areas between the sender/receiver units A and B.
