The line is used in order to automatically assemble, test and calibrate electronic monophase and polyphase kilowatt-hour meters provided by Enel, the most important provider of power and gas in Italy.

​

The line takes an area of over 400 m2 .

The medium time for operations is 4 seconds for monophase meters and 12 seconds for polyphase meters, the daily productivity is 16.800 and 5.600 pieces in 22 working hours and the efficiency is higher than 85%.

 

The process for assembly, test and calibration is structured as follows:

• Cycle start/components checking

• Base placing on conveyer belt

• Tamper contacts mounting/protections screwing

• Power groups mounting

• Breaker mounting

• Board mounting and cables soldering

• Case mounting

• Test

• Calibration (followed by verify)

• Laser marking

• Meters sealing

• Line unloading

• Label applying and meters packing

 

All operations and meters serial numbers are automatically saved on databases.
