摘要： A flow meter (1) comprises a housing (3) provided with an inlet section (3A) and an outlet section (3D), as well as a widened section located in between. This widened section is comprised of a guide portion (3B) connecting to the inlet section and a measuring portion (3C) connecting to the outlet section. A plurality of helical guide blades (5) are accommodated in the guide portion and have a core (7) inside. The measuring portion (3C) includes a measuring chamber (9) in which a measuring ball (13) can rotate in a circle. Between the core (7) and the end face (11) of the outlet section (3D) oriented to the measuring chamber there are no wall portions present. As a result of this, fluid can flow unimpededly out of the measuring chamber. For realizing a fluid flow that is as constant and fluent as possible, the core (7) is a solid core having a planar end (7A).

摘要： A flow meter (1) is comprised of two parts, that is to say, a flow unit (3) which can be fitted between fluid pipes and a detection unit (5) which is snapped on the flow unit. The flow unit has a housing (7) which accommodates a measuring chamber (17) in which there is a rotating measuring ball (23). The detection unit is snapped on the measuring chamber and has a C-shaped housing part (35). Inside the housing part (35) there is a printed circuit board (31) which is also C-shaped and is present at a distance (43) from the inner wall (35A) of the housing part. When the detection unit (5) is snapped on the measuring chamber (17), the ends (35D) of the housing part will be bent outward. As a result of the clearance (distance 43) between the inner wall of the housing part and the printed circuit board and the fact that the housing part is slidable relative to the printed circuit board, the printed circuit board is not bent.
摘要翻译：流量计（1）由两部分组成，也就是说，流体单元（3）可以安装在流体管道和检测单元（5）之间，检测单元流量单位。流动单元具有容纳测量室（17）的壳体（7），测量室（17）中存在旋转的测量球（23）。检测单元卡在测量室上并具有C形壳体部分（35）。在壳体部件（35）内部还有一个印刷电路板（31），该印刷电路板也是C形的并且与壳体部件的内壁（35A）相距一段距离（43）。当检测单元（5）卡在测量室（17）上时，壳体部件的端部（35D）将向外弯曲。由于壳体部件的内壁与印刷电路板之间的间隙（距离43）以及壳体部件相对于印刷电路板可滑动的事实，印刷电路板不会弯曲。

摘要： A flow meter 1 comprises a housing 3 which accommodates helical guide blades 5 and a core 7 located within the guide blades, and includes a measuring chamber 9 in which a measuring ball 13 can rotate in a circle. Between the end 7A of the core 7 bounding on the measuring chamber 9 and the end face 11 of the outlet section 3D oriented to the measuring chamber there are no wall portions present, and the distance 17 between the outside edge 7B of the core end 7A bounding on the measuring chamber and the inside edge 11B of outlet-section-end-face 11 oriented to the measuring chamber is smaller than the diameter D of the measuring ball 13. As a result, the fluid may unimpedely flow out of the measuring chamber as a result of which there is low flow resistance of the flow meter. Moreover, this causes no obstacles to be present between two oppositely arranged spots on the housing that may disturb a light ray for the measurement.
摘要翻译：流量计1包括容纳螺旋导向叶片5和位于导向叶片内的芯体7的壳体3，并且包括测量室9，测量球13可以在其中旋转一圈。在测量室9上限定的芯体7的端部7A和取向于测量室的出口部分3D的端面11之间不存在壁部分，并且芯部端部7A的外侧边缘7B之间的距离17 限定在测量室中，并且朝向测量室的出口部端面11的内边缘11B小于测量球13的直径D.结果，流体可以不受阻地流出测量室其结果是流量计具有低流动阻力。而且，这样就不会在壳体上两个相对布置的位置之间存在可能干扰测量光线的障碍物。
