Abstract: A method for testing an electromagnetic flowmeter and a flowmeter are described, the flowmeter having a measuring tube (2) and a coil arrangement (3, 4) for generating a magnetic field perpendicular to the direction of flow through the measuring tube (2), the current direction in the coil arrangement being periodically changed. In this connection, it is desirable for simple monitoring to be possible. For that purpose, after changing the current direction, at least one parameter of the current rise is determined and this is compared with a reference value. For this, the flowmeter has a testing device (20, 25) which, after a change-over of the current direction, determines at least one parameter (T) of the rise in the current in the coil arrangement (3, 4, 30) and compares it with a given value.

Abstract: An electromagnetic flowmeter arrangement is disclosed, having a measuring tube (2), a coil arrangement (3, 4) for generating a magnetic field substantially perpendicular to the direction of flow through the measuring tube (2), an electrode arrangement (5, 6) substantially perpendicular to the direction of flow and to the magnetic field, an evaluating device and a testing device. In this connection, it is desirable to be able to carry out testing in a simple manner. For that purpose, the testing device comprises a elements (10-13) for applying voltage to the coil arrangement (3, 4) without generating a magnetic field, and an element for determining an ohmic and/or inductive and/or capacitive coupling between the coil arrangement (3, 4) and the coil evaluating device.
