A method is provided for non-invasively determining properties of a multiphase flow which flows through an electrically conductive object. Using a single set-up having a plurality of EMAT transducers, at least one property of the multiphase flow is determined by means of at least one of a plurality of measurement methods. A device is also provided for non-invasively determining properties of a multiphase flow which flows through an electrically conductive object. At least four EMAT transducers are positionable upstream along a first object cross-section at or near the object wall and at least four EMAT transducers are positionable downstream along a second object cross-section at or near the object wall.

Method and device for non-invasively determining properties of a multiphase flow

A method for noninvasive determination of the flow or the flow rate in an electrically conductive object, through which a gaseous medium flows, by an acoustic flow meter, wherein an emitting transducer is arranged on the object wall&#x2014;and a receiving transducer is arranged spaced apart in the longitudinal direction of the object on the object wall, an ultrasonic wave is generated in the object by the emitting transducer, which is partially coupled as a longitudinal wave into the medium, and a useful signal, which at least partially results due to the longitudinal wave, is detected by the receiving transducer, the flow rate is determined from the useful signal via an evaluation device, the emitting transducer is arranged in a first position in the circumferential direction around a longitudinal axis of the object and the receiving transducer is arranged in a second position, varied in relation to the first position around the longitudinal axis, outside the main beam of the ultrasonic wave, and the width of the main beam is restricted to a sector between two contact points of a sensor mechanism.

A sensor device is provided for fitting to an object through which a medium flows, in particular to a pipeline. The sensor device comprises at least one converter device having at least one flexible converter element which comprises at least one electrically conductive conductor element and, for the sectional coverage of the object, is transposable to an operating position, in which it is at least partially arranged about a longitudinal axis. The converter device comprises a resetting device having at least one transmission element which is arranged on the converter element. The resetting device is provided for the setting and/or resetting of the converter element in the operating position.
