摘要： PROBLEM TO BE SOLVED: To provide a flow measuring device having high followability even in a condition having violent flow fluctuation.
SOLUTION: An ultrasonic signal transmitted from the first vibrator 2, received by the second vibrator 3, and amplified by an amplifying circuit 7 is compared with a reference voltage by a waveform comparison means 8 and a zero-point comparison means 9, and an inversion timing of output is detected by a waveform determination means 11, and clocked as a reception point of the ultrasonic signal by a clocking means 12. Setting of the reference voltage of the zero-point comparison means 9 can be changed by a voltage setting means 10. Since a change with time of the reception point of the ultrasonic signal generated following a set voltage change by the voltage setting means 10 is determined to be smaller than a clocking resolution of the clocking means 12, the resolution of a propagation time can be heightened by determining the propagation time by averaging a measurement result from the clocking means 12 by a time operation means 13, while changing gradually the reference voltage. Since continuous repeated measurement is not performed, flexibility of a measurement interval is enhanced, to thereby enable flow measurement having high followability to a flow change.

摘要： PROBLEM TO BE SOLVED: To actually measure and correct delay time, before and after a repetitive operation, and at changeover, since accuracy of the delay time in repeated measurements with the inversion of transmission and reception directly affects the measurement accuracy.

A delay time correcting means 22 infers the operation time of the delay means during the repeated operation, based on three kinds of delay times. COPYRIGHT: (C)2008,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide an ultrasonic flowmeter of high trackability, even under intense flow fluctuation conditions, and moreover, which is reduced in electric power consumption.
SOLUTION: Although the propagation time of ultrasonic waves propagating between the first oscillator 2 and the second oscillator 3 is measured by a measuring control means 4 and the measuring means 4 is operated in synchronism with synchronous clocks, supplied from a low-speed quartz oscillation circuit 15 and a high-speed CR oscillation circuit 16, the flowmeter is operated synchronized with the high-speed clock supplied from the high-speed CR oscillation circuit 16, only in the last portion of the propagation time measurement, and is operated in synchronism with the low-speed clock supplied from the quartz oscillation circuit 15, at other times. The operation time of the high-speed clock, consuming high electric power, is thereby restrained to be a minimum, and a sampling interval can be set short, flow measurement capable of tracking flow changes with high trackability becomes possible.

摘要： PROBLEM TO BE SOLVED: To provide a measuring device for flow having high tracking capability, even under conditions where the flow speed and/or flow rate fluctuate severely.
SOLUTION: The ultrasonic wave signal transmitted from the first oscillator 2 and received by the second oscillator 3 is detected by the detection means 8 with the number of zero-cross points of the reception waves, with the number previously determined is detected. The clocking means 9 measures the elapsed time from the start of transmission of the first oscillator 2 to each zero-cross point, and the time operation means 11 obtains the propagating time by obtaining the mean time; thus the measurement resolution of the clocking means can be enhanced by the number of detections of the zero-cross points; and since the intermittent measurements are allowed, the flexibility of the measurement is enhanced, and the measurements that are high in trackability with respect to the fluctuations of the flow can be attained.

摘要： PROBLEM TO BE SOLVED: To prevent a value of a display means from increasing when gas is not used, and reduce integration errors when the gas is used.
SOLUTION: Output of a passage flow quantity computing means 4 is added as an auxiliary integrated value to an auxiliary integrating means 7, which is cleared every time a measured time of a timer means 8 reaches a prescribed value. In a determining means 9, the auxiliary integrated value is compared with a determination threshold value, which becomes greater with a time measurement value of the timer means 8. By adding the auxiliary integrated value as an integrated value to a main integrating means 11 only when the auxiliary integrated value is greater, a quantity of flow detected when a fluid is not used is cleared, and a quantity of flow detected when the fluid is used is not cleared and added as an integrated value. It is therefore possible to prevent the integrated value from increasing when the fluid is not used and reduce integration errors when the fluid is used.

摘要： PROBLEM TO BE SOLVED: To provide a flow rate measuring apparatus for setting a reference voltage in response to a fluctuation of a amplitude level of a received signal of an ultrasonic wave during measurement of a flow rate, withstanding the fluctuation of the amplitude level and accurately measuring.
