Abstract
A flow sensor for flowing media with a cylindrical housing (2) and with a sensor element located in the housing (2), the housing (2) preferably having an outside thread (3) and being screwable into a union (4) of a pipe (5) or into an opening of a connecting piece (43). The flow sensor (1) has very high measurement accuracy while still being economically producible. There is a lifting body (6) which projects into the flowing medium, the lifting body (6) being movably guided on the housing (2) and depending on the flow (7) of the medium to be monitored, can be moved against the reset force of a reset element which is located between the housing (2) and the lifting body (6), and the sensor element is made as a noncontact proximity switch (18, 20) which produces a signal that is dependent on the position of the lifting body (6).
