Abstract
(EN) The disclosed flow measurement structure (10) used in a flow measurement device (1) is provided with a conduit (20) through which flows the gas to be measured, and a diverter (21) which diverts gas flowing through the conduit (20) and conducts the diverted gas to a detection element (12) for measuring the flow amount of said gas. An inlet (31) of the diverter (21) is provided in the periphery of the conduit (20). The conduit (20) is provided with an inclined section (50) which, provided upstream of the inlet (31), guides the gas towards the center of the conduit (20).
(FR) L'invention porte sur une structure de mesure d'écoulement (10), qui est utilisée dans un dispositif de mesure d'écoulement (1), laquelle structure comporte un conduit (20) à travers lequel s'écoule le gaz à mesurer, et un élément de dérivation (21) qui dérive le gaz s'écoulant à travers le conduit (20) et qui conduit le gaz dérivé vers un élément de détection (12) pour mesurer la quantité d'écoulement dudit gaz. Une entrée (31) du dispositif de dérivation (21) est disposée dans la périphérie du conduit (20). Le conduit (20) comporte une section inclinée (50), qui, disposée en amont de l'entrée (31), guide le gaz vers le centre du conduit (20).
