7.2 Maintenance
Contact your local representative for maintenance or repair.
7.2.1 Admonitions for replacement of flow sensor in separate systems
Specific calibration data for each flow sensor are determined during factory calibration. Flow
sensor specific data must be set in the UFC 030 ultrasonic flow converter when a flow sensor is
replaced.
• Enter value of flow sensor primary constant GK in menu 3.01.09 (it is specified on the
nameplate).
• If the new flow sensor has a different meter size, you have to program this menu 3.1.8.
• Also set the full-scale range for Q
100%
in menu 3.1.1.
• Make a zero check after setting of new data.
