Measuring device for volume or mass flow of medium in pipeline, comprises grounding disc with conductive carrier material having electrically conductive, chemically stable plastic coating in regions that are in contact with medium

摘要

The device comprises a measuring pipe (2), and a grounding disc (23) with a conductive carrier material. The carrier material is provided with an electrically conductive, chemically stable plastic coating in the regions that are in contact with the medium and the angled end regions (18) or the measuring-tube flanges (19) and the pipeline flanges (20) in the installed state. The grounding disc is made of high grade steel. The device comprises a conductive plastic coating of polytetrafluoroethylene.
