摘要： PROBLEM TO BE SOLVED: To provide a resources usage measuring device and a control circuit thereof capable of inhibiting degradation of nonvolatile memories to enhance reliability of data storage. SOLUTION: When flow rate variation ΔQ of gas is measured more than the smallest accounting unit of 1 m 3 (step S102; N), writing period WP is set up at a usual writing period WP1 (step S103); whereas when ΔQ is measured less than 1 m 3 (step S102; Y), writing period WP is set up at a writing frequency WP2 that is reduced from the usual writing period WP1 (step S104). Thus, nonvolatile memories can be protected from degradation, resulting from meaningless iteration of writing despite of no variation in flow-rate integrated value, as conventionally. Based on conditions of batteries, for example, the output voltage between terminals or the period of use (calendar year), and the like, by controlling to enhance writing period during the end of the lifetime of a battery, reliability is enhanced in data storage.

解决方案：当测量气体的流量变化ΔQ大于1m 3 的最小计费单元（步骤S102; N）时，写入周期WP以通常的写入周期WP1 （步骤S103）; 而当ΔQ被测量小于1m（步骤S102; Y）时，写入周期WP以从通常写入周期WP1减小的写入频率WP2建立（步骤S104）。因此，如传统上那样，不管流速积分值没有变化，非易失性存储器都可以免受降级的影响，这是由于无意义的写入迭代。基于电池的条件，例如，终端之间的输出电压或使用期限（日历年）等通过控制以提高电池寿命期间的写入周期，在数据存储中提高了可靠性。版权所有（C）2008，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide a flow rate measuring device for automatically and accurately detecting in a simple way occurrence of pulsation or mix of noises without unnecessarily increasing power consumption. SOLUTION: When a variation ▵Q per unit time of an instantaneous flow rate is a preset value or more (Step S101: Y), a pressure sensor measures pressure, and when the fact that a variation ▵P per unit time of the pressure is a preset value or more (Step S102:Y) is continued over a preset sampling frequency (Step S104:Y), the occurrence of pulsation in gas is determined (Step S105). In this case, the pressure of the gas is measured at a frequency higher than the preset sampling frequency for a preset time by the pressure sensor and information for its measurement result is recorded or output. When the occurrence of the pulsation in the gas is determined over the preset frequency, an alarm part issues an alarm. COPYRIGHT: (C)2004,JPO

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 accurately detect leakage in a meter apparatus, such as an ultrasonic meter apparatus for outputting the measurement values of the instantaneous flow rate of a fluid flowing in a measuring flow path at relatively short setup intervals. SOLUTION: A flowless state recognizing means measures determination times C as the number of times of the measurement value q ave less than a predetermined threshold Y and outputted at the setup intervals during a decision period D. When the decision number of times C becomes the predetermined setup decision times M of 2 or more, it decides that a flowless state is generated, and a state in which the flowless state is not generated during the decision period D, is sensed as being a leakage state.

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.
