摘要
To provide an ultrasonic multiphase flowmeter, an ultrasonic multiphase flow rate measurement program and a multiphase flow rate measurement method using an ultrasonic wave that can accurately measure the flow rate of a multiphase flow by detecting the position of an interface between phases by an operation processing of at least one of data on reflected ultrasonic wave and data on a flow velocity distribution.;An ultrasonic multiphase flowmeter has ultrasonic wave transmitting/receiving means 2 that transmits an ultrasonic wave into a fluid and receives a reflected wave thereof, flow velocity distribution calculating means 7 that calculates a flow velocity distribution from data on the reflected wave, interface position determining means 8 that has at least any of a difference operation section 81 that performs a difference operation of the flow velocity distribution and a binarization operation section 82 that performs a binarization operation of the flow velocity distribution and determines an interface position based on information on the operation, and flow rate calculating means 9 that calculates a flow rate from the flow velocity distribution and the interface position.
