    • A vane type meter includes an outer meter housing in which a cup-shaped impeller housing and cup-shaped counter housing superimposed on the impeller housing are mounted. The impeller housing is provided in the peripheral wall thereof with a plurality of rectangular, inwardly tapering inlet channels extending substantially tangential to the inner surface of the peripheral wall and with a plurality of upper outlet channels, of a number equal to that of the inlet channels and constructed substantially in the same manner as the latter. An impeller is arranged in the interior of the cup-shaped impeller housing for rotation about its axis and having a shaft extending into the counter housing. A plurality of radially extending ribs, equal in number to that of the inlet channels, project from the bottom wall of the impeller housing upwardly towards the impeller and a further plurality of radially extending ribs equal in number to that of the first mentioned plurality of ribs, project downwardly from the bottom of the counter housing toward the impeller.
    • 叶片式仪表包括外部仪表壳体,其中安装了杯形叶轮壳体和叠置在叶轮壳体上的杯形计数器壳体。 叶轮壳体在其周壁中设置有多个矩形向内锥形的入口通道,其基本上与周壁的内表面相切地延伸,并且具有数个等于入口通道数量的多个上出口通道 并且基本上以与后者相同的方式构造。 叶轮布置在杯形叶轮壳体的内部,用于围绕其轴线旋转并且具有延伸到反向壳体中的轴。 与入口通道数量相等的多个径向延伸的肋从叶轮壳体的底壁朝向叶轮突出,并且还有多个径向延伸的肋与第一个提到的多个肋的数量相等 从柜体的底部朝向叶轮向下突出。
