Plan bottle checkweighers around the smallest meaningful weight difference, normal product and tare variation, pack transfer, line speed, reject confirmation and traceable test evidence.
Speak directly with Oxford Vision Systems about dynamic weighing of filled bottles.
Illustrative bottling-line scene.
Provide filled bottles across the weight range, their dimensions and the required product spacing. Specify the decision limits and the action for an out-of-range bottle. Trial the transfer onto and off the weighing conveyor, including unstable bottles, consecutive rejects and the normal variation in production conditions.
Compare bottle checkweigher performance tests Separate tare variation, liquid movement and physical rejection before setting an acceptance window.
The useful comparison is the weight of an acceptable filled bottle against the weight of a real fault, measured through the production transfer.
Record empty-bottle, cap and label variation alongside the filled weight. A heavier bottle can mask a low fill, so a gross-weight decision needs evidence from the complete pack rather than nominal product weight alone.
List underfill, overfill and missing-component cases separately. If the weight distributions overlap, weight alone may not distinguish the fault; identify any additional inspection needed before agreeing an acceptance window.
Trial the narrowest base, tallest bottle and least stable fill condition. Assess entry and exit transfers, guides and bottle movement during the weighing interval, including the transition after an upstream stop.
Provide minimum gaps as well as average bottles per minute. Touching or irregularly arriving bottles may require handling changes before a reliable individual weight decision can be made.
Test isolated and consecutive failures with good bottles immediately before and after them. Include the reject destination and confirmation signal so the result remains linked to the bottle actually removed.
Record the recipe, bottle format, decision limits and challenge pack identity. Agree who may change these settings and what check is required when a different bottle, closure or fill target is introduced.
The right choice changes with filled bottles, closures and bottle-to-bottle tare variation, smallest meaningful weight difference and acceptance window, your line layout and required results.
Use normal production bottles and known faults at the intended transfer conditions. Record format, speed, spacing, weight result and reject outcome together, so an acceptable static reading is not mistaken for proven in-line performance.
Separate unstable handling, normal tare spread and actual fill variation before changing limits. Retain examples near each decision boundary and state which faults remain outside the demonstrated capability.
Set out the checks after a format change, a failed challenge or an unexplained rise in rejects. The trial report should identify the responsible action, affected stock and route back to production.
Use the bottle checkweighers specification checklist to prepare the application, then agree the acceptance checks and production records before comparing proposals.
Your final solution for dynamic weighing of filled bottles must reflect the law, current standards and site-specific risks that apply to your installation.
