<p>A device for the volumetric filling of containers, comprising a vessel (1) containing the fluid to be filled, a supply line (2), at least one filling head (3) and a solenoid valve (10) for controlling the fluid flow, characterized in that it is provided with a volumetric metering (6) means inserted in the said supply line and formed by a flowmeter, the device also comprising an electronic transducer circuit (7) provided with a programmable counter. During a filling cycle the electric signal outputted by the flowmeter reaches the electronic transducer circuit, which converts it into square pulses, said pulses being counted by the said counter. When the number of pulses reaches a preset number preprogrammed in the counter, the electronic circuit sends a signal acting on the solenoid valve, to close it and thereby terminate the filling cycle.</p> |
