Abstract

A method for capturing at least one flow property of a flowing fluid medium (120) is proposed wherein at least one sensor element (116) is used. The sensor element (116) comprises at least one heating element (122) and at least two temperature measuring sensors (124). The sensor element (116) is used to capture at least one first measurement variable (156) and at least one second measurement variable different from the first measurement variable (156). The first measurement variable (156) and the second measurement variable can be influenced by the flow property. At least one correction in particular at least one correction factor and/or at least one correction vector is generated from the first measurement variable (156) and the second measurement variable. The flow property is determined from the first measurement variable (156) and the second measurement variable taking into account the correction.
