Abstract:
A sensor for detecting position and/or movement in space and/or for detecting fluid-properties comprising at least one transmitter and at least one receiver which are enclosed by a fluid, characterized in that the at least one transmitter generates cyclic fluid density fluctuations and the at least one receiver detects the change in transit time and/or the phase shift and/or the frequency change and/or the amplitude change.
