Title (EN) GAS FLOWMETER
(FR) DÉBITMÈTRE DE GAZ
(JA) ガス流量計
Abstract:
(EN) Provided is a gas flowmeter comprising: a device main body that air-tightly accommodates a fluid to be measured; an inlet part that guides the fluid to be measured into the device main body; an outlet part that discharges the fluid to be measured from the device main body; and a connection part that is connected to the outlet part. The gas flowmeter further comprises: an ultrasonic-type flow rate measuring part that is connected to the connection part and calculates the flow rate of the fluid to be measured that flows internally; and a flow path member that is connected to the connection part and has the same flow path shape as that of the flow rate measuring part. The flow rate measuring part and the flow path member are connected to the connection part in a vertical direction so that a side of an inflow entrance into which the fluid to be measured flows faces downward.
(FR) La présente invention se rapporte à un débitmètre de gaz comprenant : un corps principal de dispositif qui loge de façon étanche à l'air un fluide à mesurer; une partie d'entrée qui guide le fluide à mesurer dans le corps principal de dispositif ; une partie de sortie qui évacue le fluide à mesurer depuis le corps principal de dispositif; et une partie de raccordement qui est reliée à la partie de sortie. Le débitmètre de gaz comprend en outre : une partie de mesure de débit de type à ultrasons qui est reliée à la partie de raccordement et calcule le débit du fluide à mesurer qui s'écoule à l'intérieur ; et un élément de trajet d'écoulement qui est relié à la partie de raccordement et présente la même forme de trajet d'écoulement que celle de la partie de mesure de débit. La partie de mesure de débit et l'élément de trajet d'écoulement sont reliés à la partie de raccordement dans une direction verticale de telle sorte qu'un côté d'une entrée d'écoulement entrant dans laquelle le fluide à mesurer s'écoule est tourné vers le bas.
(JA)  ガス流量計であって、被計測流体を気密に収容する装置本体と、装置本体へ被計測流体を導入する入口部と、装置本体から被計測流体を排出する出口部と、出口部に接続される接続部とを備えている。さらに、接続部に接続され、内部を流れる被計測流体の流量を演算する超音波式の流量計測部と、接続部に接続され、流量計測部と流路形状が同一形状である流路部材とを備えている。流量計測部および流路部材は、被計測流体が流入する流入口側を下方に向けて、鉛直方向に接続部と接続されている。
