ABSTRACT:
An apparatus for determining the flow of matter passing through a boundary surface, which is provided with at least one sensing layer corresponding to the boundary surface, and presents a known or predetermined, finite resistance to the material flow, and wherein an optical indicator is provided in the sensing layer for obtaining a first measured value of a quantity dependent on the mean concentration of matter in the sensing layer, and wherein a second measured value of this quantity is known on one side of the sensing layer, or can be determined by means of another optical indicator provided in a second sensing layer, and, further, wherein an evaluation unit is provided for inferring the material flow from the difference of the two values measured.
