◆ Product Overview
This Rotary Bottle Checkweigher System consists of two synchronized checkweighing units to achieve accurate net weight testing for filled pharmaceutical bottles.
1. Checkweigher A first captures the tare weight of empty bottles.
2. Tare weight data is transferred to Checkweigher B in real time.
3. Checkweigher B measures the gross weight of filled medicine bottles after filling.
4. The system automatically subtracts the pre-recorded tare weight to calculate the precise net weight of medicine inside each bottle.
5. Products out of preset weight tolerance will be automatically identified and rejected without interrupting continuous production.
This tare-gross weight separation design eliminates weight deviation caused by inconsistent empty bottle weight, greatly improving weighing accuracy for pharmaceutical filling lines.
