摘要： PROBLEM TO BE SOLVED: To provide a flowmeter which can detect a leak in a gas supply passage on the downstream side of a flow-rate detection means, which removes a noise component and by which the used flow rate of a gas is integrated precisely.
SOLUTION: The flow rate of the gas flowing in the gas supply passage is detected by the flow-rate detection means 11, and whether the flow rate detected by the means 11, a prescribed measurement reference value and a dead reference value are large or not is judged by a flow-rate judgment means 12. The dead reference value is set at the measurement reference value or less, and the flow rate at the measurement reference value or more is integrated by a flow-rate integration means 13 as the used flow rate. A leak judgment means 16 judges that the leak is generated in the gas supply passage on the downstream side of the means 11, when a period in which the flow rate of the gas is judged to be the fluid reference value or more by the means 12 is regarded as continuing, and when the period reaches a prescribed leak judgment period.

摘要： PROBLEM TO BE SOLVED: To surely detect whether a cut-off valve is functioned correctly or not, by a simple technique, without impairing convenience for a user, in a gas meter provided with the cut-off valve and a safety means. SOLUTION: An abnormality deciding and control circuit 40 monitors gas pressure by a pressure sensor (pressure measuring means), and conducts control to bring the cut-off valve 94 into a closed condition, when the presence of a prescribed condition is determined in the gas meter by a safety unit 90, for example, when an earthquake is generated, or when a battery is run down. The occurrence of abnormality in a valve opening and closing operation for the cut-off valve is decided when pressure is reduced in the gas pressure thereafter, and when pressure increase having a prescribed level or more of fluctuation amount is caused further thereafter.

摘要： PROBLEM TO BE SOLVED: To provide a flow rate measuring device for measuring a flow rate or a flow velocity with the propagation of sonic waves to a fluid to be measured while automatically detecting in a simple way that the device is installed in an environment where noises are frequently mixed and avoiding lowering the accuracy of measuring the flow rate or the flow velocity resulting from noises or false signals. SOLUTION: A noise determination control part 41 determines that the noises are mixed (generated) when ultrasonic waves having a frequency within a frequency band possibly causing the noises is detected during a non-sampling period. A flow rate measuring operation control part 42 controls a flow rate value computation part 30 and a flow rate value accumulation part 50 to compute a flow rate value while ignoring signals when output from a ultrasonic propagation time measurement part 20 corresponding to a normally impossible flow rate value or flow rate pattern of time transition.

摘要： PROBLEM TO BE SOLVED: To perform precise leakage judgment of pipes, even if the judgment is performed in a condition when a floor heater or the like is operated approximately continuously for thirty days, and moreover in a condition where measured flow rate values obtained by measure ment are influenced by pressure variations from neighboring houses.
SOLUTION: When a measured value of a flow rate variation during thirty seconds is larger than 2 1/h, in first judgment, leakage judgment is not performed. When the measured value is not larger than 2 1/h, it is judged that there are no leakages, if the average value of individual measured flow rate values during the thirty seconds is not larger than 1.5 1/h. When a measured value of a flow rate variation during five minutes is larger than 10 1/h, in second judgment, leakage judgment is not performed. When the measured value is not larger than 10 1/h, it is judged that there are no leakages if the average value of individual measured flow rate values during the five minutes in not larger than 1.5 1/h. When a measured value of a flow rate variation during one hour is larger than 38 1/h, in third judgment, leakage judgment is not performed. When the measured value is not larger than 38 1/h, it is judged that there are no leakages, if the average value of individual measured flow rate values during the one hour is not larger than 1.5 1/h. When leakage judgment is not performed continuously during a division of thirty days, it is reported that there is a leakage.

摘要： PROBLEM TO BE SOLVED: To provide a flowmeter whose power consumption is nearly identical in an environment in which a pressure pulsation is generated and in a case where the pressure pulsation is not generated. SOLUTION: In a momentary-flow-rate computing part 20b, a processing operation in which a mean value of a flow rate in each fetch cycle obtained by fetching a flow rate obtained from a flow-rate measuring part 4 in a prescribed fetch cycle in the prescribed number of times of a fetch operation is used as a momentary flow rate is regarded as one flow-rate measurement, and the flow-rate measurement is repeated intermittently in a measuring cycle as a prescribed time interval. In an integrated-flow- rate computing part 20c, a flow rate obtained by multiplying the momentary flow rate by the measuring cycle is regarded as an integrated flow rate in the measuring cycle. A pulsation decision part 20e monitors the existence of the pressure pulsation of a gas passing the measuring part 4 on the basis of an output of the measuring part 4. When the pressure pulsation is detected, the fetch cycle is made longer than that in its non-detection to such an extent that the pressure pulsation does not influence the momentary flow rate. The measuring cycle is made longer than that in its non- detection in such a way that the power consumption is equal to that in its non- detection. COPYRIGHT: (C)2004,JPO

摘要： PROBLEM TO BE SOLVED: To detect abnormality of microcomputer operation surely without omission. SOLUTION: A gate circuit 3 outputs a pulse having the time width corresponding to a delay time of a delay circuit 2 from rise of a clock pulse CLK generated in a microcomputer 11. The pulse is inputted into a charging/ discharging circuit 4, and the charging/discharging circuit 4 charges a capacitor C2 in a period when the pulse is outputted and discharges the capacitor C2 through a resistance 2 in another period. A voltage comparing circuit 5 monitors a voltage between both ends of the capacitor C2, and when the voltage between both ends of the capacitor C2 is lowered below a reference voltage Vref, the microcomputer 11 is determined to be abnormal, and an output value is inverted.
