System and method for inspecting a fluid

A system for inspecting a fluid, the system comprising:

• a lighting system for illuminating a fluid under inspection in an image detection area;
• an image capture system for capturing a sequence of images of the fluid in the image detection area;
• magnetic means for generating a magnetic field towards the image fluid under inspection, the magnetic means comprising at least one coil for generating the magnetic field, such that ferromagnetic particles in the fluid under inspection are prevented from reaching, or removed from, the image detection area;
• wherein the image capture system is configured to capture an image of the fluid located in the image detection area before the magnetic field is applied and an image of the fluid located in the image detection area after the magnetic field is applied, the image detection area being therefore free of ferromagnetic particles;
• and
• processing means configured to compare said images of the fluid under inspection and count the ferromagnetic particles in the fluid.
