The system guarantees the volume inside the bottle by means a flowmeter.
Flowmeter’s output is in pulses, that are processed by an electronic board in communication with the PLC and with the electrovalves that drives the opening of the filling valve. When the number of counted pulses equals he number of pulses set for the working size, the filling valve is closed.
This system allows not using the level vent tube, which means:
The inductive flow meter is suitable for conductive products, in case of not conductive products a mass flow meter can be used.
The absence of the vent pipe give the possibility of an automatic dummy bottles. Even if it is supplied as an option, it is extremely suggested because allows:
In case of budget limitation, the machine can be supplied with manual dummy bottles that can be quickly screwed to the valve terminal.
The upper and lower manifolds for fluids (product, CO2, compressed air) and signal distribution are realized with a special treatment in the sliding parts to guarantee a long life.
The gas snifted from the bottles at the filling end, are collected in to the central manifold and discharged in one single point.
The use of modulating valves for product level and pressure control inside the bowl, allows keeping the product stable to avoid foaming. All the valves are positioned outside the machine in an easy accessible position .
The parameters for each bottle size are memorized in recipes that can be quickly loaded from touch panel.
