Doppler type ultrasonic flowmeter, flow rate measuring method using doppler type ultrasonic flowmeter and flow rate measuring program used in this doppler type ultrasonic flowmeter |
摘要 |
<p>A doppler ultrasonic flowmeter 10A includes: a Udflow unit 13 for calculating the speed of a great number of reflectors 25 contained in a fluid 12 to be measured; a flow-speed distribution calculating element 70 for calculating the flow-speed distribution of the fluid 12 to be measured within a fluid tube 11 by performing computation processing for the flow-speed data of the reflectors 25 received from the Udflow unit 13; a center position detecting element 71 for detecting the center position of the fluid tube 11; a flow-speed distribution calculating member 67 having an area selecting element 72 which allows the user to select a division area within the fluid tube 11 in units of the division area; the flow-speed distribution being calculated for the selected division area using the reflectors 25; and a flow calculating member 68 for measuring the flow by further performing computation processing for the flow-speed distribution of the fluid 12 to be measured. Furthermore, the doppler ultrasonic flowmeter 10A includes a display monitor 39 for displaying the calculation results output from at least one of the flow-speed distribution calculating member 67 and the flow calculating member 68. The present invention having such a configuration provides a doppler ultrasonic flowmeter, a flow measurement method, and a flow measurement program, having the advantage of enabling measurement of the flow-speed distribution and measurement of the flow, regardless of irregularities in the measurement results of the flow-speed distribution.</p> |
