摘要： PROBLEM TO BE SOLVED: To provide a fluid flow measuring device for measuring normally even if a flow rate and/or a flow velocity change from small to large in a short period of time.
SOLUTION: When the flow rate changes suddenly from a small flow rate to a large flow rate, a gain value of a variable gain amplifier is set to the gain value exceeding the maximum gain value (beforehand obtained by experiment) which is necessary when the maximum flow rate of flow rate range measured in a passage flows. After setting, a next gain value is set to (the last gain value ± (the last gain value)/2) according to a determination result of an error comparator 6.

摘要： PROBLEM TO BE SOLVED: To improve a measurement accuracy by shifting two transducers from a center in an ultrasonic flowmeter to place them in positions capable of detecting an average flow velocity.
SOLUTION: This flow rate measuring device comprises a rectangular passage 1 with a rectangle section, and a first sound wave transducer 3 and a second sound wave transducer 4 placed in the upper stream and the down stream of the rectangular passage 1 with crossing a long side of the passage 1 that transmit and receive the sound wave. The first sound wave transducer 3 and the second sound wave transducer 4 are individually arranged by decentering a prescribed length from the center of the short side of the rectangular passage 1. Thereby, the flow rate of a fluid is measured by the time difference of sound wave propagation between the transducers 3, 4, and flow accuracy is high by maintaining a flow coefficient constant without the influence of flow velocity distribution in the passage 1.
