Abstract: Provided are a method and a device for determining a flow rate through a pipe. A first measurement device is provided which determines the flow profile of the fluid in a first region using a Doppler frequency shift measurement method, and a second measurement device is provided which determines the flow profile of the fluid in the pipe in a second region using a travel time measurement method.
