摘要： PROBLEM TO BE SOLVED: To provide an ultrasonic type gas meter capable of measuring pulsation, and suppressing increase of current consumption.
SOLUTION: In this ultrasonic type gas meter, a flow rate of gas is measured by a sing-around method by using an ultrasonic wave transmitted/received between a first ultrasonic sensor 21 and a second ultrasonic sensor 22 arranged in a gas passage 3. The gas meter is equipped with a counter circuit 26 for measuring an arrival time until an ultrasonic wave generated from one ultrasonic sensor between the first ultrasonic sensor and the second ultrasonic sensor by a driving pulse reaches the other ultrasonic sensor, a sing-around control circuit 25 driven by sending the driving pulse to one ultrasonic sensor in response to reception of the ultrasonic wave by the other ultrasonic sensor, a profile data collection circuit 11 for collecting each arrival time measured by the counter circuit 26 at every time when the ultrasonic wave is received by the other ultrasonic sensor, and a control circuit 10 for profiling a change of the gas flow rate based on a change of collected arrival times.

摘要： PROBLEM TO BE SOLVED: To provide amount measuring equipment of resources used wherein the reliability of data storage can be improved by preventing the deterioration of an EEPROM, and its control circuit. SOLUTION: When flow rate variation ΔQ of gas is judged as at least 1 m 3 which is charging minimum unit (step S102;N), write-in frequency WP is set as a normal write-in frequency WP1 (step S103). When flow rate variation ΔQ of gas is judged as at most 1 m 3 (step S102;Y), write-in frequency is set as write-in frequency WP2 which is smaller than the normal write-in frequency WP1 (step S104). Deterioration of the EEPROM can be prevented which is to be caused by the repetition of futile writing although there is no variation in flow rate integral like before. On the basis of condition of a battery, e.g. on the basis of an output voltage between terminals, usable years (calendar years), etc., control is performed which increases write-in frequency in lifetime last stage of the battery, and the reliability of data storage is improved.

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.
