Title (EN) FLOW RATE MEASUREMENT DEVICE
(FR) DISPOSITIF DE MESURE DE DÉBIT
(JA) 流量計測装置
Abstract:
(EN) A gas meter (100) which serves as a flow rate measurement device is provided with: a flow rate measurement unit (104) for measuring at regular time intervals the flow rate of gas flowing through a flow passage; a pressure measurement unit (132) for measuring the pressure of the gas within the flow passage; an electric power supply unit (134) for supplying electric power to the pressure measurement unit (132); and an appliance identification unit (116) for identifying, on the basis of the flow rate value of the gas, an appliance being used. The gas meter (100) is further provided with a measurement interval control unit (138) which, on the basis of both the flow rate value of the gas and operating information from the appliance identification unit (116), identifies a state in which gas is not being used, a state in which appliance identification is being performed, and a state in which appliance identification is not being performed. Then the measurement interval control unit (138) controls the electric power supply unit (134) on the basis of each of the states and changes the intervals of on and off of electric power supplied to the pressure measurement unit (132).
(FR) La présente invention concerne un compteur de gaz (100) qui sert de dispositif de mesure de débit et qui est pourvu : d'une unité de mesure de débit (104) pour mesurer, à des intervalles réguliers, le débit de gaz qui s'écoule dans un passage d'écoulement; d'une unité de mesure de pression (132) pour mesurer la pression du gaz dans le passage d'écoulement; d'une unité d'alimentation en énergie électrique (134) pour fournir de l'énergie électrique à l'unité de mesure de pression (132); et d'une unité d'identification d'appareil (116) pour identifier, en fonction de la valeur de débit du gaz, un appareil qui est utilisé. Le compteur de gaz (100) est en outre pourvu d'une unité de commande d'intervalle de mesure (138) qui, en fonction de la valeur de débit du gaz et d'informations de fonctionnement à partir de l'unité d'identification d'appareil (116), identifie un état dans lequel du gaz n'est pas utilisé, un état dans lequel une identification d'appareil est effectuée, et un état dans lequel une identification d'appareil n'est pas effectuée. Ensuite, l'unité de commande d'intervalle de mesure (138) commande l'unité d'alimentation en énergie électrique (134) en fonction de chacun des états et change les intervalles de marche/d'arrêt de l'énergie électrique fournie à l'unité de mesure de pression (132).
(JA) 流量計測装置であるガスメータ(100)は、流路に流れるガスの流量を一定時間間隔で計測する流量計測部(104)と、流路内のガスの圧力を計測する圧力計測部(132)と、圧力計測部(132)に電力供給を行う電力供給部(134)と、ガスの流量値に基づいて使用器具を判別する器具判別部(116)を備える。さらに、ガスの流量値および器具判別部(116)の動作情報に基づいて、ガス非使用状態、器具判別実施状態および器具判別非実施状態を判別し、それぞれの状態に応じて電力供給部(134)を制御し、圧力計測部(132)へ供給する電力をオン/オフする間隔を変更する計測間隔制御部(138)を備える。
