A device for monitoring the flow of a fluid ( 3, 13 ) flowing through or from a conduit ( 2 ), such as a lubricant or an article treatment fluid; it includes light-emitting elements ( 1 ) arranged to irradiate a light radiation towards the flow and sensor elements ( 4 ) for sensing the image projected onto them by the fluid ( 3, 13 ) struck by the light radiation, the sensor elements ( 4 ) generating at least one output signal ( 11, 12 ) based on the presence thereon of the sensed fluid image. The method implemented by the device is also claimed.
