Abstract
An ultrasonic flow rate measuring device includes a flow path, a partition plate that is inserted from an aperture to partition the flow path into plural sections, an ultrasound transmission body, plural ultrasonic transducers that are provided in positions facing a bottom plate such that an ultrasonic wave transmitted from one of the ultrasonic transducers through the ultrasound transmission body is reflected by the bottom plate and received by the other ultrasonic transducer, a measurement circuit that measures an ultrasonic propagation time between the plurality of the ultrasonic transducers; and a calculation circuit that obtains a flow rate of the target fluid based on a signal from the measurement circuit.
