Abstract:
A magnetoinductive flow-measuring process for measuring the flow rate of a fluid, comprising the following steps:providing a measuring tube having a longitudinal axis through which the fluid moves and which is equipped with two measuring electrodes positioned along an imaginary connecting line that extends substantially perpendicular to the axis of the measuring tube; generating a periodically alternating magnetic field extending in a direction substantially perpendicular to the axis of the measuring tube and perpendicular to said imaginary connecting line; collecting a voltage differentiated from a reference potential at one or both of the measuring electrodes in each cycle of the periodically alternating magnetic field; determining an electrochemical noise voltage by summing the voltage collected at one or both of the two measuring electrodes relative to the reference potential and averaging the summary signal as a function of time, and displaying the electrochemical noise voltage to a user and/or providing the electrochemical noise voltage to the user for further processing.
