The complex is designed for the water meter assembly line. It features four workstations. After being assembled, water meters are fed to four quality control points, which check the assembly quality and operational characteristics. Meters are transported between the assembly and control areas via two-level flow line equipped with roller guides. If a meter fails to pass quality control, it goes to the lower level, which returns it to the assembly area, where it is either fixed or rejected. After passing the quality control, the meters end up on the final assembly table. There, they are completed, packed and sent for shipping.
