This chapter can be used as separate document to support the staff of flow test facilities
when calibrating the meter. Experienced staff may use the Short Guide.
All information in this chapter relates to FLOWSIC600 devices marked ‘II
+
’ and the
MEPAFLOW600 CBM software V1.2.00 or higher.

Short Guide to flow calibration
Verification and installation
Check the meter for possible damages due to delivery.
Cross-check the serial number on the main plate with the serial number in the
Manufacturer Data Report (MDR) as well as the size. design pressure, design
temperature, flow range and meter factor.
Install the flow meter on the flow test facility (
Connect up the FLOWSIC600 (power supply cable, pulse outputs and RS485 MODBUS
connections
).
Remove the front cap and switch Parameter write lock to the unlock position (
Close the front cap and switch on the power supply.
Parameter setup
Establish an online connection between FLOWSIC600 and MEPAFLOW600 CBM
software (User Access Level: "Service"; Password: see Service Manual). (
Verify the key data on the "Meter information" page of MEPAFLOW600 CBM with the
data of the Parameter report of the MDR (
).
Switch the meter into Configuration Mode.
Open the "Meter calibration" wizard in MEPAFLOW600 CBM (select Tools / Meter
calibration).
Enter the pressure and temperature values on the wizard page 1 of 4 (
Check whether the meter is correctly set for the calibration (
).
Click "Write to meter".
Determination of adjust factors
Provide a gas flow rate within the valid flow range in the test line.
Check the performance of the meter and check the "Meter status" table (
Adjust the zero phase if necessary (
).
Prepare MEPAFLOW600 CBM data recording if required (
Carry out the flow verification. When finished, calculate the Weighted Mean Error
(WME) and the adjust factor(s) and enter them in the meter (
The MEPAFLOW600 CBM Calibration wizard supports the determination and
setting of factors and coefficients (
).
