摘要

Topic Boundary position of phase and phase is detected at the time of flow measuring of multi-phase flow, the ultrasonic reflected wave or among velocity distributions by at least calculating processes the data of one side, the ultrasonic multi-phase flow quantitative meter which precision can detect the flow of multi-phase flow well, the multi-phase flow quantitative measurement method of using the ultrasonic multi-phase flow quantitative measurement program, and the ultra wave is offered.Solutions It discharges the ultra wave to the fluid, the ultrasonic sending and receiving expedient the flux distribution calculation expedient the finite difference arithmetic logical unit 81 where executes the finite difference operation of 7 where calculates flux distribution from the data of 2 which at the same time receives that reflected wave and the aforementioned reflected wave and the aforementioned flux distribution or the binary conversion arithmetic logical unit 82 which executes the binary conversion operation of the aforementioned flux distribution it possesses each of them at least, the boundary position fixing expedient it possesses with 8 which decides boundary position on the basis of the information of particular operation and the aforementioned flux distribution and the flow calculation expedient 9 which from the aforementioned boundary position calculates flow.
