Coriolis flowmeter with multiple flow tubes

A Coriolis flowmeter with multiple flow tubes, comprising a flow sensor and a flow transmitter, wherein:

• the flow sensor comprises a sensor housing, a sleeve, and two symmetrical flanges;
• a sensor assembly is arranged in the sensor housing, the sensor assembly comprises at least two flow tube groups, and each flow tube group of the at least two flow tube groups comprises at least two flow tubes;
• at least two flow tube pairs are provided by the at least two flow tube groups, each flow tube pair of the at least two flow tube pairs is formed by two flow tubes with same size and geometry in different flow tube groups of the at least two flow tube groups, each flow tube pair is fixedly connected together by at least one pair of node plates, a measurement area of the flow tubes is between an innermost pair of the at least one pair of node plates, and each flow tube group is connected to a driver and a detector;
• and
• the at least two flow tube groups comprise a first flow tube group and a second flow tube group, all flow tubes in the first flow tube group are connected by a first detector fixing plate, and all flow tubes in the second flow tube group are connected by a second detector fixing plate, and the detector is fixedly arranged between the first detector fixing plate and the second detector fixing plate.
