ABSTRACT:
An apparatus for monitoring the flow of fluid in the pipeline has a hollow housing with a control element movably supported therein. The control element is movable under the action of the fluid flow, from an initial position to a position triggering a switching operation and is biased towards its initial position by a biasing system. A support ring is fixedly coupled to an inner wall of the hollow housing and has a central opening therein. The control element is composed of a connecting element which extends through the wall of the pipeline and through the central opening in the housing, which connecting element has a first end coupled to a magnet and a second end connected to a flow deflecting body. The connecting element is pivotably mounted to the support ring about an axle extending therethrough. A flow diverter or a seal assembly is utilized for preventing fluid flow from the pipeline from going around the connecting element and through the central opening into the housing interior.
