摘要： An ultrasonic fluid measurement instrument is capable of highly accurate fluid measurement. A measurement part is provided forming a plurality of split channels partitioned by partition boards halfway across a fluid channel, and at least a pair of ultrasonic transmitter-receivers for transmitting ultrasonic waves into the fluid flowing through the split channels and receiving ultrasonic waves that have passed through the fluid. Further, an arithmetic unit calculates the flow velocity and/or flow volume of the fluid according to the propagation time of the ultrasonic waves. The measurement part further includes an approach channel for preliminarily rectifying the fluid flowing to the split channels.

摘要： The present invention provides an ultrasonic fluid measurement instrument capable of highly accurate fluid measurement. Measurement part (1) is provided forming plural split channels (3) partitioned by partition boards (2) halfway across the fluid channel, and at least a pair of ultrasonic transmitter-receivers transmit ultrasonic waves into fluid flowing through split channels (3) and receive ultrasonic waves that have passed through the fluid. Then, an arithmetic unit calculates at least one of flow velocity and flow volume of the fluid according to the propagation time of the ultrasonic waves. Measurement part (1) is further provided with approach channels (5) and (6) for preliminarily rectifying fluid flowing to split channels (3).
