Abstract
A device for determining a flow-rate-dependent variable of a flowable and conductive medium in a guide body for guiding the medium includes a magnetic-field-generating device for generating a first magnetic field that separates mobile charge carriers in the medium and a magnetic-field-sensitive measuring arrangement for determining a second magnetic field that is generated by the mobile charge carriers. The magnetic-field-sensitive measuring arrangement includes a first magnetic-field-sensitive measuring device having a magnetic-field-sensitive and optically excitable material, an optical excitation unit for the optical excitation of the first magnetic-field-sensitive measuring device, and an optical detection unit for detecting a measurement signal that correlates with a change and/or a strength of the second magnetic field. An evaluation circuit is configured to determine the flow-rate-dependent variable, measurement signals of at least two different magnetic field states influencing the determination of the flow-rate-dependent variable.
