摘要： A magnetoinductive flowmeter incorporates an electromagnetic circuit with at least one coil and a minimum of two detachably interconnected components of a magnetic material. One of the components features a resiliently deformable spring section that presses against the other component. The result is an easy-to-assemble magnetoinductive flowmeter that can be manufactured with substantial production tolerances.

摘要： A magnetoinductive flowmeter and a method for operating same utilizing a measuring tube through which flows an electrically conductive medium, as well as two measuring electrodes and a magnet with two field coils positioned parallel to each other on mutually opposite sides of the measuring tube. The measuring electrodes are so positioned that their connecting line extends along an essentially perpendicular vector relative to the direction of flow and to the magnetic field as well as through the cross-sectional center of the measuring tube. For normal flow-measuring operation, the two field coils are so energized that an essentially homogeneous magnetic field is generated, permeating the medium flowing through the measuring tube, while for determining the flow rate the voltage present between the two measuring electrodes is collected at one or both measuring electrodes and measured against a reference potential. The normal flow-measuring operation is intermittently interrupted and the two field coils are energized in a manner as to generate an inhomogeneous magnetic field that permeates the medium flowing through the measuring tube, and the voltage present between the two measuring electrodes is collected. This permits a diagnosis of the flowmeter.

摘要： A process for determining the phase portion of a medium in open and closed pipes, especially for use in connection with a process for determining the volume flow, with the help of at least three condenser plates extending basically over the entire height of the pipe and with the help of a control and evaluation circuit, in which at least one of the condenser plates has an alternating voltage applied to it by the control and evaluation circuit and the current flowing between the condenser plate with the voltage appled to it and at least one other condenser plate is recorded by the control and evaluation circuit. The process is designed so that the current between at least two condenser plates is recorded by the control and evaluation circuit from two different groups of condenser plates separated by the vertical line of the pipe. The current between individual condenser plates in the first group of condenser plates and at least one condenser plate in the second group of condenser plates is recorded by the control and evaluation circuit in sequence; the current of the highest plate reached by the surface level of the medium in the first group of condenser plates is standardized by the control and evaluation circuit using the currents of the lower-lying condenser plates in the first group of condenser plates; and the standardized current from the highest condenser plate reached by the surface level of the medium in the first group of condenser plates is evaluated as a measurement for the position of the surface level of the medium relative to the highest condenser plate reached by the surface level of the medium in the first group of condenser plates.
