The equipment is based on the principle of fixed volume (measuring cup) filling, and the volume of the stainless steel measuring cup is adjusted according to different filling capacities. There are manual, electric, and computer-based methods for adjusting the volume, as well as overall and individual adjustments.

1. Manual adjustment of volume requires personnel with operational experience to stop, and the adjustment can only reach the approximate capacity. It also requires accurate measurement with a measuring cup.

2. Electric and computer-based methods for adjusting volume are available, and the equipment is equipped with a capacity panel without a digital display. The filling machine only requires stainless steel measuring cups with exquisite and reasonable singing skills, and the common errors are within national standards, without the need for measuring cups.

3. Overall adjustment refers to the consistent adjustment of the volume of all filling valves in the filling machine, and it is equipped with a capacity display, making it easy to control in operation.

4. Individual adjustment refers to the individual adjustment of each filling valve on the equipment, with the capacity scale as a reference. For ordinary purposes, it also requires measurement adjustment through the use of measuring cups.
