Description

Technical Field

[0001] The utility model relates to the technical field of flow meters, in particular to an anti-corrosion device for flow meters. Background Art

[0002] Flow meter, also known as flow meter, measures the instantaneous flow rate and cumulative volume of liquid, and can also quantitatively control the liquid. Flow meter has the characteristics of high accuracy, long life, simple operation and maintenance. Flow meter is mainly used in industrial production process, energy measurement, environmental protection engineering, transportation, biotechnology, scientific experiments, marine meteorology, rivers and lakes, etc.

[0003] After a long period of use, the outer surface of the flow meter is usually corroded, which affects the accuracy of the flow meter and reduces its service life. At present, a plastic shell is usually set on the outer surface of the flow meter to protect the flow meter from corrosion.

[0004] During the use of the existing flow meter, although the flow meter can be protected by a plastic shell to prevent the flow meter from being corroded, the plastic shell will become easily damaged when the temperature is too low. Some flow meter anti-corrosion devices connect the stainless steel shell by fastening bolts, thereby wrapping the flow meter inside to prevent the flow meter from being corroded. Although this method improves the protection effect of the flow meter, the fastening bolts are prone to oxidation corrosion after long-term use, making it inconvenient to replace and disassemble the flow meter anti-corrosion device, reducing work efficiency. For this reason, we propose a flow meter anti-corrosion device. Utility Model Content
