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.read more

Fluid flow meter
TL;DR: In this article, a fluid flow rate meter is disclosed for measuring the flow of fluid in a partially filled conduit or channel, including an electromagnetic probe adapted for mounting in the conduit below the low water mark thereof to produce a sensed velocity signal, and a liquid height pressure transducer including an air tube having a bubble-producing opening adjacent the probe for generating a fluid height signal that modifies the sensed velocity signals to produce the resultant signal that corresponds with the average velocity of fluid flow.

Flow measuring device
TL;DR: In this paper, a flow meter includes a flow path through which a fluid flows; a pair of transceivers for sending and receiving an ultrasonic wave propagating across the flow path; and a flow calculation section for calculating a flow rate of the fluid flowing through the flowpath based on a result of the ultrasonic waves being sent and received by the pair of Transceivers.
