Invensys (Shandong) Instrument Co., Ltd. has been granted a utility model patent for a “vortex flowmeter suitable for high-heat environments”, according to information released by the China National Intellectual Property Administration (CNIPA). The patent authorization publication number is CN223756110U, with a filing date of March 2025.
Designed for High-Temperature Industrial Environments
The patented design targets vortex flowmeter applications in high-temperature and thermally demanding industrial environments, where measurement stability, sealing performance, and installation efficiency are critical. Vortex flowmeters are widely used in industries such as chemical processing, power generation, metallurgy, and energy systems, where accurate flow measurement under harsh conditions is required.
Structural Optimization for Improved Sealing
According to the patent abstract, the device includes a vortex flowmeter body with positioning flanges fixed at both inlet and outlet ends. Sealing gaskets are installed on the surface of the positioning flanges, and a positioning assembly is evenly arranged on the side of the gasket away from the flowmeter body.
A key innovation lies in the coordinated mechanical adjustment system. By rotating a bolt, an internal gear ring is driven to rotate, which engages multiple drive gears. This synchronized motion ensures that multiple threaded rods rotate uniformly, driving a plate-and-disc mechanism that presses against the pipe flange surface evenly.
Improved Installation Efficiency and Reliability
Unlike traditional methods that require sequential tightening of multiple screws, this design ensures uniform force distribution across the sealing gasket. As a result, the interface between the flange and positioning plate achieves more consistent sealing performance.
This mechanism offers several advantages:
Faster installation and replacement in large-scale industrial deployments
Reduced manual labor requirements
Improved sealing uniformity across flange surfaces
Lower risk of fluid leakage caused by uneven fastening
Industry Significance
The innovation addresses common pain points in flowmeter installation and maintenance, particularly in high-temperature process environments where thermal expansion and mechanical stress can affect sealing integrity. By improving both efficiency and reliability, the patented design supports safer and more cost-effective industrial operations.
Conclusion
The patented high-temperature vortex flowmeter from Invensys (Shandong) reflects ongoing advancements in industrial instrumentation, focusing on installation efficiency, sealing consistency, and operational reliability. The technology is expected to be particularly valuable in large-scale industrial systems requiring frequent maintenance or rapid equipment replacement.
