  • Method for operating a magnetoinductive flowmeter
    Patent number: 11441931
    Abstract: The disclosure relates to a magnetoinductive flowmeter. In order to detect gas bubbles in a measuring tube, and thus an incompletely filled measuring tube, the control signal with which the magnetic field generating device is actuated is designed as an alternating rectangular pulse with time delays. A first pulse time delay is provided after a positive rectangular pulse and a second pulse time delay is provided after a negative rectangular pulse during one period, wherein no magnetic fields are provided during the pulse time delays.
