摘要： PROBLEM TO BE SOLVED: To provide an integrating flowmeter which can obtain accurately an integrated flow rate of fluid passing a specified channel, without depending on presence and absence of a pulsation state. SOLUTION: The integrating flowmeter is provided with a thermal flow sensor for measuring an instantaneous flow rate of the fluid passing the specified channel, a flow rate measure which integrates the instantaneous flow rate measured by the flow sensor, outputs a unit flow rate signal when the integrated value reaches a prescribed unit flow rate, and resets the integrated value, and a flow rate integrating means which counts the unit flow rate signal output from the flow rate measure, and obtains an integrated flow rate of the fluid passing the specified channel. The integrating flow meter is provided especially with a ripple detecting means for detecting a ripple state of the fluid in the channel, and an instrument range changing means which sets widely instrumentation range by the thermal flow sensor, when pulsation is detected by the pulsation detecting means.

摘要： PROBLEM TO BE SOLVED: To improve instrumentation accuracy by performing simply and effectively temperature compensation and/or pressure compensation of an output of a thermal flow sensor. SOLUTION: The flowmeter is provided with the thermal flow sensor and a flow rate calculating means for obtaining a simultaneous flow Q of fluid according to a flow velocity v obtained by the flow sensor. The flow sensor is especially provided with a temperature sensor for obtaining a temperature t of the fluid, and a temperature correction table in which temperature variation characteristics of the thermal flow sensor are stored as a correction value ▵X(v, t) per unit temperature concerning the flow rate v and the temperature t. Further, the flowmeter is provided with a flow rate correcting means for correcting the flow rate v as a flow rate V at a reference temperature by setting V=v+▵X(v, t)×(t-to) according to the flow rate v and the temperature t of the fluid and the correction value ▵X(v, t) registered in the temperature correction table.

摘要： PROBLEM TO BE SOLVED: To provide a gas sensor for avoiding the occurrence of unneeded gas shut-off by transitory failure.
SOLUTION: A gas meter 1 comprising a controller 2; a flow rate sensor 3; an external sensor 4; an isolation valve 5; a display section 6; and a communication I/F 7. The gas meter 1 is connected to a setting apparatus 8 via the communication I/F 7, and further is connected to a monitoring center 72 via a telephone line 71. In this case, the controller 2 acquires data from the flow rate sensor 3 at a fixed period, performs flow rate sensor failure judgement operation, based on the data, and stores failure in the controller 2 as "flow rate sensor failed state" when the controller 2 detects the failure in the flow rate sensor 3 for a specific number of times continuously.

摘要： PROBLEM TO BE SOLVED: To provide a gas meter capable of determining whether a governor is built in a gas consumption equipment used in a user side or not, without requiring fine valve opening regulation for a cut-off valve, even when a low flow rate of gas consumption condition is continued in the user side, and capable of determining the presence of generation of gas leakage.
SOLUTION: A gas equipment using condition determination part 7 determines the occurrence of the gas leakage, or that the gas consumption equipment not provided with the governor is used in a downstream, when a reduction-directional change of a level of a prescribed variation or more is detected in response to pressure reduction generated inside the gas meter in own house caused, for example, by an influence of receiving passively pressure drop of gas in a neighboring house via a gas pipe or the like, and when the gas flow rate is not increased to the prescribed variation or more even after a prescribed time lapses.

摘要： PROBLEM TO BE SOLVED: To achieve resetting without using any monitoring sensors and communication equipment when a strong earthquake cuts off gas that cannot be reset in a gas meter for detecting the earthquake for cutting off gas. SOLUTION: After a controller 19 detects a strong earthquake for cutting off gas that cannot be reset, measurement for specific time is started. When a phenomenon, such as earthquakes, is not detected during the period, the cutoff of gas that cannot be reset is set to the cutoff of gas that cannot be reset, thus performing control so that gas can be used by pressing down a reset switch and automatic reset.

摘要： PROBLEM TO BE SOLVED: To provide a flowmeter capable of measuring the flow regardless of pressure fluctuation with a reduction in probability of transition from a 1st measurement mode to a 2nd measurement mode. SOLUTION: The flow measurement part 3 measures intermittently the instantaneous flow of the fluid passing through the flow path 1. The flow measurement part 3 is capable of selecting the 1st measurement mode for measuring the instantaneous flow with a longer time interval and smaller power consumption or the 2nd measurement mode for measuring the instantaneous flow with the shorter time interval and larger power consumption. The operation selection part 4c discriminates synchronism and asynchronism between the time interval of measurement and a variation in pressure of fluid passing through the flow path 1 by using a variation pattern of the instantaneous flow obtained by the 1st measurement mode, if it is recognized, directs the interval adjusting part 4b to change the measurement interval in the 1st measurement mode. The operation selection part 4c directs the mode selection part 4a to select the 2nd measurement mode if the variation width of the pressure variation is wider than the prescribed threshold value.

摘要翻译：要解决的问题：提供一种流量计，其能够随着压力波动的测量而测量流量，同时降低从第一测量模式转换到第二测量模式的概率。解决方案：流量测量部件3间歇地测量流过流路1的流体的瞬时流量。流量测量部件3能够选择用于测量瞬时流量的第一测量模式，具有更长的时间间隔和更小的时间间隔功耗或第二测量模式，用于测量瞬时流量，具有更短的时间间隔和更大的功耗。操作选择部分4c通过使用通过第一测量模式获得的瞬时流量的变化模式来识别测量的时间间隔和通过流路1的流体的压力变化之间的同步和异步，如果被识别，则指示间隔调整部4b改变第1测定模式的测定间隔。如果压力变化的变化幅度大于规定的阈值，则操作选择部分4c指示模式选择部分4a选择第二测量模式。版权所有（C）2005，JPO＆NCIPI

摘要： PROBLEM TO BE SOLVED: To enable safely and surely the reset of a gas meter even when two or more causes having the same order of priority are generated in the gas meter detecting an abnormality and issuing a gas shutoff alarm or the like.
SOLUTION: When two or more abnormalities causing shutoff or alarm are detected, and a release order is required for reset from the shutoff state caused by a shutoff cause or from an alarm state caused by the alarm cause, and the orders of priority of each shutoff cause and alarm cause are the same, even after releasing one shutoff cause or alarm cause, a controller 18 does not release the other one or more shutoff causes or alarm causes, holds the causes internally, and thereby releases each cause, while confirming the causes one by one.
