Abstract:
1. A flow measuring apparatus ( 300 , 500 ) for measuring a flow of a fluid ( 130 ) within a conduit ( 120 ) including one or more walls ( 110 ), said apparatus ( 300 , 500 ) including a transducer arrangement ( 100 A, 100 B) including at least one transducer for emitting ultrasonic radiation into the flow ( 130 ) and at least one transducer for receiving ultrasonic radiation from the flow ( 130 ) in operation, and a signal processing arrangement ( 310 ) for generating signals to excite the transducer arrangement ( 100 A, 100 B) and for processing received signals provided by the transducer arrangement ( 100 A, 100 B) for generating output signals from the signal processing arrangement ( 310 ) indicative of properties of the flow, characterized in that said transducer arrangement ( said transducer arrangement ( said signal processing arrangement (
