Embodiment Construction

[0011] The present invention will be further described below in conjunction with the embodiments and the accompanying drawings.

[0012] refer to figure 1 with figure 2 , the present invention includes a flow tube, a support tube 5 , a sub-body 4 and a connecting flange 6 .

[0013] The flow tubes are U-shaped micro-bent tubes, two of which form a group, and each group has the same shape. The two sets of flow tubes are installed up and down, and are divided into upper and lower groups, that is, upper flow tube 1 and lower flow tube 2. The upper flow tube 1 and the lower flow tube 2 have an included angle of 115 degrees formed by the centerlines of the horizontal pipe and the inclined pipe, and the horizontal pipe and the inclined pipe are curved with a smooth transition.

[0014] At least one damping plate 3 is jointly fixed on the outer walls of the two inclined straight tubes on both sides of the upper flow tube 1 and the lower flow tube 2 . In this embodiment, at least...

Abstract

A multi-runner Coriolis mass flowmeter sensor fluid main part comprises flow pipes, a support pipe, distribution bodies and connecting flanges. Two ends of each flow pipe are respectively fixedly connected to one sides of the distribution bodies. The other sides of the distribution bodies are fixedly connected with the connecting flanges. The support pipe is fixed between the two distribution bodies. The multi-runner Coriolis mass flowmeter sensor fluid main part is characterized in that the flow pipes are U-shaped and divided into an upper group and a lower group. Every two flow pipes form one group. Each group of flow pipes is of the same shape. The outer walls of two inclined straight pipes on two sides of each group of flow pipes are jointly fixedly provided with at least one damping plate. Compared with the prior art, the multi-runner Coriolis mass flowmeter sensor fluid main part has the advantages that the defects of currently-popular mass flowmeters are overcome, and the multi-runner Coriolis mass flowmeter sensor fluid main part is low in pressure loss, simplified in structure, high in flexibility, less prone to environmental influence, and the like.

Description

technical field [0001] The invention relates to a mass flowmeter sensor, in particular to a fluid main part in a multi-channel type Coriolis mass flowmeter sensor. Background technique [0002] Coriolis mass flowmeter (hereinafter referred to as Coriolis flowmeter) is to introduce fluid into the tube while the flow tube vibrates synchronously, so that it flows forward along the tube, and the tube body will force the fluid to vibrate up and down together with it. In order to resist this forced vibration, the fluid will give the pipe body a reaction force perpendicular to its flow direction. Under the action of this so-called "Coriolis effect force", the vibration of the pipe body is asynchronous, and the inlet section of the pipe and the There will be a difference in the time sequence of the vibration of the outlet pipe, and this difference is proportional to the mass flow rate of the fluid flowing through the pipe body. By detecting the difference in time through the circui...
