Abstract
A device for producing foam, particularly of a liquid such as milk or coffee, includes a liquid source, a source of air or another gas, a mixing device in fluid communication with the liquid source and air source adapted to mix the liquid coming from the liquid source with the air coming from the air source to generate a foam of the liquid. The device further includes a duct in fluid communication with the mixing device downstream of the mixing device, with the foam flowing along the duct in a flow direction. The device includes a foam sensor associated with the duct and a radiation source adapted to generate a radiation which strikes the duct along an irradiation direction incident to the flow direction. The foam sensor includes a first photodiode placed on the irradiation direction or a second photodiode placed along a diffusion direction.
