摘要： An ultrasonic flowmeter includes a flow passage and an ultrasonic generator/detector for measuring the flow rate in the flow passage wherein the ultrasonic generator/detector is equipped with a piezoelectric body having electrodes on the opposed surfaces thereof, one of which is used as an ultrasonic wave generating/detecting surface and faces the flow passage. The lengths of the sides of the generating/detecting surface is so determined that the vibration in the electrode direction is the main mode, preferably that the ratio of the lengths of the sides of the transmission/reception surface to the thickness is not greater than 0.8. Consequently, because the flow meter uses the thickness longitudinal vibration of the piezoelectric body as the main mode, the ultrasonic generator/detector has a high sensitivity, a high speed response and a small size and the ultrasonic flow meter has a high accuracy and is compact.

摘要： For the purpose of solving the above problems, the present invention includes: transmission/reception means provided in a flow path f or performing transmission/reception using a state change of fluid; repetition means for repeating the transmission/reception; time measurement means for measuring a time of propagation repeated by the repetition means; flow rate detection means for detecting a flow rate based on a value of the time measurement means; and number-of-times change means for changing to a predetermined number of repetition times. With such a structure, an influence caused by'a variation of a flow can be suppressed by changing the number of repetition times so as to be suitable for a variation. As a result, reliable flow rate measurement with a high accuracy can be achieved.
