Richter, M.M.Richter2022-03-082022-03-082010https://publica.fraunhofer.de/handle/publica/309401The invention relates to a device for capturing at least one flow parameter, comprising a series fluid circuit (10), a first flow restriction (12), a first measurement area (14), a second flow restriction (16), and a second measurement area (18). A first sensor (20) is provided in order to capture a first quantitative dimension for a pressure present in the first measurement area. A second sensor is provided in order to capture a second quantitative dimension for a pressure present in the second measurement area. An evaluation device (24) is provided, designed for determining a flow rate of a fluid flowing through the series circuit by using the dimensions captured by the first and second sensor (20, 22), and/or for determining whether a stoppage of the first flow restriction (12), the second flow restriction (16), or a fluid area adjacent to the second fluid area is present.en621patent2008EP07988
