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 comprises light-emitting means (1) arranged to irradiate a light radiation towards said flow and sensor means (4) for sensing the image projected onto them by to the fluid (3, 13) struck by said light radiation, said sensor means (4) generating at least one output signal (11, 12) based on the presence thereon of the sensed fluid image. The method implemented by the aforesaid device is also claimed. |
