Abstract
A method for operating a magnetic-inductive flowmeter includes: detecting the noisy raw measurement signal having a first signal path by a signal sensor with high impedance by the pair of electrodes; passing the detected, noisy raw measurement signal on to a first signal processing device; processing the detected, noisy raw measurement signal by the signal processing device at least into a noise-removed flow measurement signal; outputting the noise-removed flow measurement signal via a working signal interface; detecting the detected, noisy raw measurement signal of the first signal path with a second signal path; and transmitting the detected, noisy raw measurement signal at least indirectly to the first signal processing device and/or a second signal processing device. The first signal processing device and/or the second signal processing device also carry out a frequency analysis of the detected, noisy raw measurement signal. A corresponding magnetic-inductive flowmeter is also disclosed.
