Meter e.g. flow meter, housing for pipeline, has flexible wall section limiting flow path and provided in body and connecting tubes, where wall section is deformable by fluid pressure and flow path for fluid is formed in housing and tubes

摘要

The housing (1) has a body (2) and two connecting tubes (3, 4) that are connected with a pipeline. A flow path for fluid that is to be measured is formed in the housing and the tubes. A flexible wall section (6) limiting the path is provided in the body and the tubes, where the wall section is deformable by fluid pressure. The section is formed by a polymer section connected fluid-tightly with the body or to the tubes and is formed of silicon rubber and elastomer i.e. thermoplastic elastomer. A hollow chamber of the wall section includes a vent hole that is guided into a housing environment.
