Abstract

Abstract The invention relates to an apparatus for in-line checking of the liquid level in phials, particularly for the pharmaceutical industry. The apparatus comprises a conveyor device, an electronic station for checking the liquid level in the phial and for storing the information, a device for expelling the phials to be discarded, a control and check panel with a counterforthe pieces. The electronic station for checking the liquid level in the phial comprises an IR radiation emitting diode and a photocell detector as well as electronic components for discrimination of the electric response indicating anomalous or normal filling of the phial and for processing the corresponding signals.
