Quality evidence / fill-level diagnosis
Bottled Water Filling Level Consistency
Fill-level variation should be investigated with controlled observations, not an immediate setting change. Record the bottle and cap lot, product-water condition, running state, machine speed and sample position first.
Answer first
Hold one variable set constant, collect a time- and position-identified sample, and separate repeatable station patterns from random variation. The project must define its own measurement method and acceptance limit; this site does not invent a universal tolerance.
Diagnostic sequence / hold variables constant
Separate the symptom from its possible causes
Record a controlled sample before adjusting settings. The sequence below avoids changing several variables at once.
| Observation step | Record | Decision enabled |
|---|---|---|
| Identify the sample | Bottle revision, lot, time and position | Whether geometry or one position repeats |
| Freeze conditions | Water supply state, speed and recent stop history | Whether operating state explains the change |
| Measure consistently | Buyer-approved method and reference point | Comparable results across samples |
| Map the pattern | Random, time-based, station-based or format-based | Which cause branch to investigate first |
| Retest one change | One adjustment plus before/after evidence | Whether the correction is repeatable |
Reference values require project-specific confirmation. No universal fill-level tolerance is stated here; the buyer and supplier must approve the project criterion.
Not suitable for
Boundaries that need a different platform or review
- Applying an arbitrary universal fill-level tolerance
- Changing multiple machine settings before recording the symptom
- Using mixed bottle revisions in one diagnostic sample
Inputs required
Evidence to provide before confirmation
- Bottle and cap lot or sample identifiers
- Product-water supply state and machine running condition
- Speed, time, station or valve position and observed pattern
- Project-approved measurement method and acceptance basis
Machine function
What happens at this machine or decision boundary
- Describe the variation before attempting a correction.
- Separate bottle geometry, supply, station and transfer influences.
- Create evidence that can be repeated during FAT or troubleshooting.
Configuration decisions
Options that must appear in the proposal
- Visual reference, fill height or another approved measure
- Sample frequency and positions across the machine
- Conditions that must remain constant during comparison
Interface requirements
Upstream, downstream and utility handovers
- Product-water supply stability at the filler boundary
- Bottle geometry and transfer condition before filling
- Outfeed observations before downstream handling masks the symptom
Buyer risks
Questions to close before order
- Comparing samples taken under different conditions
- Treating bottle geometry variation as a filler fault
- Publishing an unverified tolerance as a machine guarantee
FAT checks
How to verify the agreed basis
- Approve the sample identity and measurement method before the run.
- Record time, position, result and any machine stop for each sample set.
- Retest open points under the same documented conditions.
Quotation scope
What the commercial offer should state
- Measurement method and buyer acceptance limit
- Bottle and water conditions for the test
- Sampling record and responsibility
- Open-point, correction and retest procedure
