[0006] By adopting the above technical solution, it is convenient to fix the flow meter. After fixing, it is connected to the external monitoring device through the electronic box, which is convenient to detect the operation of the flow meter.

[0007] The utility model is further arranged such that the inside of the outer shell is hollow, and the outer shell of the outer shell matches the bending angle of the measuring tube.

[0008] By adopting the above technical solution, it is convenient to protect the measuring tube and make the measuring tube closely adhere to the inner wall of the outer shell.

[0009] The utility model is further arranged such that the bending angle of the measuring tube is one hundred and twenty degrees, and there are two groups of folding angles in total for the measuring tube, and the folding angles are in contact with the inner wall of the outer shell.

[0010] By adopting the above technical solution, it is convenient for the liquid to flow through the inside of the measuring tube, reducing the accumulation of impurities and facilitating the cleaning of the measuring tube.

[0011] The present utility model is further configured such that the output end of the joint is connected with a flange, and a plurality of groups of openings are provided on the inner wall of the flange, and the flange is connected with an external device through the openings.

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present utility model, and should not be construed as a limitation to the present utility model.

[0023] Next, the embodiments of the present utility model will be described according to its overall structure.

[0024] A Coriolis mass flowmeter, as Figures 1 to 4 shown, includes a housing 1 and a metering tube 2. The metering tube 2 is welded below the housing 1. Connectors 201 are installed on both sides of the metering tube 2. The interior of the housing 1 is hollow. A measuring tube 4 is connected inside the housing 1. The bending angle of the measuring tube 4 is 120 degrees. There are two sets of folding angles for the measuring tube 4. The folding angles are fitted to the inner wall of the housing 1. The interior of the housing 1 is hollow, which can facilitate the flow of liquid in the measuring tube 4 and reduce the accumulation of impurities. The outer shell of the housing 1 matches the bending angle of the measuring tube 4. An electronic box 3 is welded to the bottom end of the metering tube 2, and head electronic components are installed inside the electronic box 3. Wire connectors 301 are provided on both sides of the electronic box 3. External wires are connected through the wire connectors 301, which is convenient for connecting the flowmeter to external monitoring equipment and inputting data into the external monitoring equipment.

[0025] Please refer to the figure. The output end of the connector 201 is connected to a flange 202. Multiple openings are provided on the inner wall of the flange 202. The flange 202 is connected to external equipment through the openings, which can facilitate the installation and fixation of the flowmeter and the filling machine.

[0026] Please refer to the figure. A limiting collar is installed outside the wire connector 301. The limiting collar is snap-connected to the external wire, which is convenient for the wire to rotate when the filling machine rotates, reducing wire entanglement.

[0027] During use, first connect the flowmeter to the pipeline inside the filling machine through the flange 202, and then connect the electronic box 3 to the external control unit through the wire connector 301. The electronic box 3 can effectively reduce the occupied space of the flowmeter and facilitate the overall installation of the flowmeter. When the filling machine rotates, the self-winding of the wire can be reduced through the rotating wire. Moreover, during the filling process, the liquid flows through the measuring tube 4, and the internal angle of the measuring tube 4 is set to 120 degrees, which can effectively reduce the accumulation of residues in the liquid. And when cleaning, the flowmeter is disassembled from the inside of the filling machine, and then water is injected into the flowmeter through the connector. The water flows in the measuring tube 4 to wash away the accumulated impurities. The large-angle bend can facilitate the flow of water, thereby washing away the impurities and facilitating the overall cleaning of the flowmeter.
