Description

Technical Field

[0001] The utility model relates to the technical field of flow meters, in particular to a flow meter capable of assisting docking. Background Art

[0002] A flow meter is an instrument used to measure the flow rate of fluid in a pipe or open channel. It indicates the measured flow rate and the total amount of fluid in a selected time interval. There are many types of flow meters, which can be divided into differential pressure flow meters, rotor flow meters, throttling flow meters, slit flow meters, volumetric flow meters, electromagnetic flow meters, ultrasonic flow meters, etc. according to the measurement principle.

[0003] When the flow meter is in use, the two ends of the flow meter are connected to two groups of liquid pipes respectively. The liquid in one group of liquid pipes is transported into the tube body of the flow meter, and the flow meter records and tests the flow rate of the liquid. The existing flow meter and the liquid pipe are connected and fixed by bolts. When the bolts are subjected to external force or vibration, the bolt connection position is easy to loosen or shift, resulting in a decrease in the stability of the equipment or components.
