Abstract
Methods of measuring flow properties and flowmeters having an upstream transceiver and a downstream wave transceiver, each positioned with a wave emitting surface exposed to a fluid flowing in a conduit are described, the transceiver being separated by a length L along the conduit and adapted to receive wave signals traveling in flow direction and opposite to the flow direction, respectively, and an electronic processor for extracting from travel time measurements of the wave signals flow characterizing parameters, the transceivers being adapted to generate tube waves, particularly in the audible frequency range, in the conduit and used to determine the travel time of the tube waves between the upstream transceiver and the downstream wave transceiver.
