Vorrichtung zur Ultraschall-Durchflußmessung

摘要

The inventive device consists of a housing arrangement (1) comprising a housing body (2), a housing neck (3) and a housing head (4). Two respective recesses (7) starting from each front side of the inner wall of the housing (2) are provided to accommodate holders (8) for a total of four ultrasonic transducers (6). Connecting lines (15) pertaining thereto run from the recesses (7) through a front-face groove (9) to a chamber (10) extending from the corresponding front face, whereupon said connecting lines (15) lead to pressure lines (16) disposed in the neck of the housing (3) between the chambers (10) and the interior of the head of the housing (4). A sealing o-ring joint (12) extends radially outside said recesses (7), grooves (9) and corresponding chambers (10). A disc-shaped flange (13) that is screwed to the housing arrangement (1) tenses the o-ring joint (12).
