Description

Technical Field

[0001] The utility model belongs to the technical field of metal rotor flowmeters, in particular to a backflow-proof metal rotor flowmeter. Background Art

[0002] The metal rotor flowmeter is a type of variable area flowmeter that calculates the flow rate by measuring the position of the float in the fluid. The anti-backflow metal rotor flowmeter builds on this by adding a check valve to ensure that the fluid can only flow in one direction, preventing backflow caused by pressure changes or external factors.

[0003] Most metal rotor flowmeters with backflow prevention have some drawbacks. For example, during installation, workers often need to use tools to turn multiple bolts one by one to securely connect and secure the metal rotor flowmeter to the pipeline. This operation is not only tedious and complex, but also significantly increases the time and cost required for installation. In view of this, we propose a metal rotor flowmeter with backflow prevention. Utility Model Content
