  • Patent number: 11131571
    Abstract: A system and related method is provided for correcting measurement glitches detected by a magnetic flowmeter assembly in determining a fluid flow velocity. The magnetic flowmeter assembly includes a pair of electrodes that receive an instantaneous first and second electrode potential (voltage potential), Ue1 and Ue2, so as to determine an instantaneous induced voltage Ue across the fluid. A signal processor sends a digital signal of the induced voltage (voltage signal Ue) to a micro-processor, which processes the signal data and computes the corresponding instantaneous fluid velocity, v. Moreover, an instantaneous glitch detection variable Um is computed based on the electrode potentials (Ue1 and Ue2), so as to detect the presence of measurement glitches in said electrode potentials, wherein the signal processor will provide a digital signal of Um to the micro-processor.

  • Patent number: 11092631
    Abstract: In a driver circuit having a signal generator, end stage and amplitude control, the signal outputs an analog signal to a signal input of the end stage, with an amplitude predetermined by an amplitude control value. A load output of the end stage is connected with a voltage measurement input of the amplitude control providing a load current having an electrical current level dependent on an electrical input signal applied on signal input and a load voltage having a voltage level dependent on the electrical current level of the load current. The amplitude control ascertains an amplitude deviation between actual and desired amplitude values for ascertaining an indicator value, which signals that a magnitude of a measurement voltage input is too high, if a threshold value has been exceeded and, if so, to ascertain an amplitude control value lessening further amplitude control values outputted to the amplitude control input.
