Single-phase 2P DIN rail meters, which have a low current rating (typically 5-100A) as well as basic calibration requirements have been specially made to use this design. There is a smaller footprint and throughput is optimized for high volume residential meter production. Three-phase lines have an increased footprint to accommodate 3P/4P meters that have a higher current rating (120A) requiring more space.

There are two options available. For higher volume assembly lines, we offer an automatic torque checking station or an electric screwdriver with a torque sensor. If you are producing lower volumes and don’t need the extra features of the automatic torque hand tools, then you can use a manual torque wrench and barcode record the torque measurement. The choice of which option to use will have an impact on the cycle time and cost.

The aged bench has the ability to measure and record meters via RS485 (Modbus, DLMS/COSEM), an optical port (IEC 62056-21) and via PULSE outputs. Wireless modules (LoRa, NB-IoT) are an option but require additional integration work.

Indeed, a robotic load/unload module could be used in place of the semi-automated calibration booth (in keeping with the calibrated bench design). This is recommended for production volumes greater than 15,000 units per manufacturing run/one shift.

A company that builds 8,000 meters of product production (2 independent shifts) will typically realize a ROI in the 9 to14 month range due primarily to reduced labor (4 to 6 calibration / test operators removed) and an improved initial pass yield.
