Electromagnetic flow meter, has control- and evaluating unit determining flow based on determined parameter for compensating effects of variations of ohmic and/or capacitive coupling between coil arrangement and evaluating unit

摘要: The meter has a coil arrangement with coils (3, 4) for producing magnetic field perpendicular to flow direction of medium flowing through measuring pipe (2). A control- and evaluating unit (20) controls the determines depending on voltage detected at an electrode arrangement. parameter i.e. difference arrangement, ohmic and/or capacitive coupling between unit. based determined compensating effects variations coupling. An independent claim is also included method operating electromagnetic meter.
