Abstract (en)

[origin: WO2006076998A2] The invention relates to a device for determining and/or monitoring a volume flow and/or a mass flow of a measuring medium (9) that flows in one direction of flow through a meter tube (1) having a defined inner diameter. Said device comprises a plurality of ultrasound sensors (22) that emit and/or receive ultrasound measuring signals along differently defined measuring paths, and a control/evaluation unit (23) that uses the ultrasound measuring signals to determine the volume flow and/or mass flow of the measuring medium (9) in the conduit / in the meter tube (1) according to a sound propagation method or according to the echo principle. The invention is characterized in that at least two ultrasound sensors (22) emitting and/or receiving ultrasound measuring signals on different measuring paths are positioned in an opening (10) that is disposed in the wall of the meter tube (1).
