Patent ID: 11391612

Abstract:
A coriolis mass flow meter, including: a housing body, having a flow inlet and flow outlet for a fluid medium, two measurement tubes, which are spaced apart from each other fastened to the housing body connecting the flow inlet and the flow outlet to each other, at least one electrically controllable vibration exciter for each measurement tube (23, 24), the vibration exciter being designed to cause the measurement tube to vibrate, and at least two electrically controllable vibration sensors, the vibration sensors being designed to sense the vibration of at least one of the two measurement tubes. The vibration exciter vibration sensors are spatially fixedly fastened to the housing body between the two measurement tubes and are designed as electromagnetic coils. Each coil interacts with a permanent magnet fastened to one of the measurement tubes. The permanent magnets are oriented in such a way that permanent magnets attract each other.
