FAT Checks for an Automatic Liquid Filling Machine
How buyers can turn filling volume, bottle diameter, and pump details into practical pass or fail checks for a factory acceptance test, plus what to confirm before requesting a quote.
A buyer specifying an automatic liquid filling machine should decide up front which checks must pass at the factory acceptance test, not after installation. Start with the filling volume range of 10–500 mL and the bottle diameter range of 30–110 mm, both listed as customizable, and ask the supplier to demonstrate the exact sizes you will run.
For each size, agree on a sample count and a pass or fail rule for fill accuracy and repeatability. Ask whether the single-head rotor pump is demonstrated at your target volumes and with your liquid, since viscosity and foaming can change results. Include checks for bottle handling across the stated diameter range, spillage, and changeover time between sizes. For a demonstration, request a run at the low and high ends of your range and at a typical production size.
Before requesting a quote, confirm with the supplier which volumes and bottle diameters the proposed configuration actually covers, how fill accuracy will be measured and accepted, and which test liquids and sample sizes the factory acceptance test will use.
