12 Commission the device
Commissioning the XFC or XRC is a two-part process:
 Validate the device measurement
 Place the device in service.
Validate the device measurement
The XFC and XRC are calibrated at the factory before shipping. However,
shipping and installation may introduce errors into the measurement
results. To verify measurement accuracy, perform pressure checks.
IMPORTANT NOTE:
Save the device’s data and configuration before
an
d after calibration procedures. For details on calibration or device
data
backup, refer to the Calibration and Preserve device data and
configuration
sections in the user manual (See Additional
information
.)
Validate measurement:
1. Perform static pressure (SP) and differential pressure (DP)
calibration pressure checks.
2. If it is necessary to correct errors in the measurement system,
proceed to the calibration instructions in the user manual.
Place the device in service
The following instructions provide general guidelines for placing the XFC in
service.
IMPORTANT NOTE:
The following procedure is based on the flow
computer attached to a
3-valve manifold. For all other applications,
adapt these instructions to the specific manifold.
Place the XFC in service:
1. Close the high and low pressure tap valve connections on the stream
to shut off the process flow. (See the figure below, item 6.)
