Abstract
The invention relates to a flow measuring device comprising a meter body having a conduit for the fluid, two phased-array ultrasonic transducer units spaced apart in the longitudinal direction of the conduit, which can emit and receive ultrasonic signals at different angles, a control and evaluation unit for driving the ultrasonic transducer units and evaluating the received ultrasonic signals and determining the flow using the transit time of the ultrasonic signals on the measuring paths. In order to provide an improved flowmeter with which a high measurement accuracy with good signal quality can be achieved using secant paths, it is proposed that the ultrasonic transducer units define at least two measurement paths between them, depending on the angle of the emitted ultrasonic signals, along which paths the ultrasonic signals pass from one to the other ultrasonic transducer unit, and that at least one of the measurement paths has at least one reflection on a conduit wall of the conduit and path sections are defined by the reflection or reflections.
