4 Commissioning and Configuration
4.1 Basics
4.1.1 General Notes
Commissioning essentially entails entering the plant data (for example, the measuring path,
installation angle), configuring the parameters for the output variables and response times,
and, if necessary, setting the check cycle (see Section 4.2). A zero-point adjustment is not
required.
Additional calibration of the velocity measurement by means of a network point
measurement using a reference system (for example, a pitot tube flowmeter) is only
necessary if the velocity profile along the measurement axis is not representative for the
entire cross-section (see Section 3.1.1). The calculated regression coefficients can then be
easily entered in the device (see Section 4.3).
If the gas temperature measured with the FLOWSIC100 is to be used to normalize the
volumetric flow, calibration using an external temperature is essential (see Section 4.3).
This is because the speed of sound of the real gas under normalized conditions is seldom
known.
The operating and configuration software ‘‘SOPAS Engineering Tool” (SOPAS ET) is supplied
with the device for configuring the system parameters. The required settings can be easily
configured using the software menus. Other functions (such as data backup and graphical
display functions) are also available.
If the standard settings do not provide adequate stability under all plant conditions (for
example, if the device is not deployed in line with the specifications set out in the technical
data), you can enhance system performance by optimizing the internal parameter settings.
These settings, however, must only be configured by adequately qualified personnel, since
correct operation cannot be guaranteed if the settings are defined incorrectly. Changes of
this kind should be carried out by SICK MAIHAK Service personnel only. The settings are
listed in the Service Manual.
