Embodiment
In order that those skilled in the art more fully understand technical scheme, below in conjunction with the accompanying drawings and by specific
Embodiment further illustrates technical scheme.
As shown in Figure 1-2, in the present embodiment provide a kind of coriolis mass flowmeters, it is possible to increase shunting body by
Power, and then improve the service life of flowmeter.The flowmeter includes：
Flowmeter bodies 1, the flowmeter bodies 1 include measurement pipe 13, support tube 11 and are arranged on support tube 11
Shunting body 12, the shunting body 12 is arranged on support tube 11 and is symmetrical arranged, and the two ends of measurement pipe 13 connect with shunting body respectively
Connect and the trapezoidal bending of the measurement pipe 13；
Support 2, the support 2 is fixedly installed on support tube 11 and abutted with the two ends of shunting body 12；The support 2
The one end abutted with the shunting body 12 is provided with the first deep-slotted chip breaker 21 for accommodating the shunting body 12.The present embodiment medium-height trestle 2
It is welded to connect with support tube 11.
As shown in Fig. 2 above-mentioned flowmeter bodies 1 also include be arranged in measurement pipe drive component 14, be set in measurement
Damping sheet 15 and detection part 17 on pipe 13, the shell 16 for being connected with support tube 11 and measurement pipe 13 setting within it with
