Abstract
本发明涉及一种流量测量装置，包括由塑料或至少一个塑料衬里制成的测量管，在该测量管中设置接触测量材料的电极。为了在此实现，电元件能更容易并且位置更固定地安装，按本发明建议，测量管在注塑过程中由塑料制成，各电极以及线圈接纳件以及电元件在一个共同的单独的注塑过程中一起注塑在里面。
Description
技术领域
本发明涉及一种按权利要求1的前序部分所述的流量测量装置，其具有由塑料制成的测量管。
背景技术
这种流量测量装置用设置在测量管外部的磁系统和设置在测量管中的接触测量材料的电极以磁感应的方式工作。但是也已知用不接触测量材料的电极工作的电容式流量测量装置。例如由EP 1 193 474 A1已知本身有利的磁感应或电容式的带有塑料测量管的流量测量装置。在那里，电极嵌入在塑料测量管中。
发明内容
因此本发明的任务在于，改进流量测量装置，使得电元件可以更容易且更位置固定地安装。
所提出的任务在同类的流量测量装置中按本发明通过权利要求1的特征部分的特征解决。
其它有利的结构在从属权利要求中说明。
本发明的核心在于，测量管在塑料的一个注塑过程中制成，电元件在一个共同的单独的注塑过程中一起注塑在里面(einspritzen)。因此按简单的方式实现电元件的持久且机械保护的布置。在此，所述的浇注不必立即构成器具的外壳。也可以有利的是，所述元件按这种方式在位置上固定。
在另外的有利的实施形式中设定，至少一个过程接头也一体地并且由塑料制成地成型在测量管上。这产生能简单装配的布置，其中不再需要在测量管与过程接头之间的焊接连接。
在另外的有利的实施形式中设定，至少一个一起注塑在里面的电元件是作为感应式流量测量装置工作的流量测量装置的磁系统。作为感应式流量测量装置的结构因此是特别有利的。
因此有利地设定，用于控制电极和/或磁系统的电路或电元件一起注塑在里面。
如已经提及的那样，特别有利的是，共同的注塑是构成外壳的注塑。
如下结构是特别有利的，即在该结构中，通过注塑构成的外壳设有金属的表面。因此可以按简单的方式实现高效的电屏蔽，使得没有从外部作用的电磁场干扰可以作用到浇入的电子元件或电极上。
有利地设定，电极是分散的金属的导电的电极。
有利的结构也在于，电极是分散的由导电塑料构成的电极或在测量管的塑料中的区域。
为了固定磁系统，有利的是，在磁感应的流量测量装置中，用于磁系统的引导辅助件或固定辅助件一体地一起注塑在上面(anspritzen)。
同样情况适用于，用于导线或布线的引导辅助件和固定辅助件一起注塑在上面。
电容式的流量测量装置也可以有利地如此构造。
附图说明
在附图中描述并且随后详细解释本发明。
图1显示流量测量装置的透视图。
具体实施方式
图1显示按本发明的流量测量装置的透视图，其包括测量管1和注塑在上面的壳体2。为了制造由测量管1和过程接头10构成的基础单元，采用传统的注塑方法。在此如所提及的，过程接头(即由塑料制成的连接凸缘)与测量管一体地按注塑方法制造。但是这仅仅是在该实施例中的情况，一起成型过程接头不是强制必需的。
在此其它不可见的电连接线和必要时电连接线的导线引导元件例如接线柱或夹子按注塑技术注塑或粘接到基础单元上。
电元件例如电路、控制件或用于电极的前置放大器等可以在固定之后被一起浇注进去。此外在感应式流量测量装置中，磁系统和所有元件一起注塑或固定在测量管外部。
最后进行最后的浇注，其按图1所示的方式必要时也将所有装配在测量管上的元件一起浇注进去，也就是说，最后在最后的注塑步骤中形成壳体地一起浇注进去。在壳体2上的一个位置，连接线3朝外引出。
这不仅在制造方面是明显简单的，而且得到整体上非常结实的结构单元，它提供高的机械耐久力。
另外，由塑料制成的壳体以及必要时从壳体伸出的测量管段必要时与过程接头一起设有金属层，例如通过蒸镀形成金属层。
通过这样用导电中间层涂布的金属涂层被良好附着地施加。该金属涂层是优良的但是能明显简单制造的电屏蔽。因此在这样的塑料系统中实现这样的屏蔽度，其不亚于带有金属测量管和金属壳体的金属的结构形式。
