摘要：
A device for detecting at least one flow parameter includes a fluidic series connection of a first flow restriction, a first measurement area, a second flow restriction, and a second measurement area. A first sensor is provided for detecting a quantitative first measure of a pressure existing in the first measurement area. A second sensor is provided for detecting a quantitative second measure of a pressure existing in the second measurement area. An evaluator is provided which is configured to determine, while using the measures detected by the first and second sensors, a flow rate of a fluid flowing through the series connection, and/or to determine whether there is an occlusion of the first flow restriction, of the second flow restriction, or of a fluid area adjoining the second measurement area.
