The group standard for the invention patent “Variable‑Throttle Flowmeter” has been successfully released, signaling that domestically produced flow meters are poised for a major breakthrough.

On August 24, 2026, with Tangshan Fengrun District Zhanwang Automation Equipment Co., Ltd. (hereinafter referred to as Zhanwang Automation) taking the lead and several instrumentation companies and universities participating, the China Technology Market Association organized the successful release of the group standard “Variable-Orifice Flowmeter,” designated as T/TMAC 454—2026.

On September 17 of the same year, an invention patent for a variable‑area flowmeter was granted, with patent number 202311124203.7. Developed by the Outlook Automation Technology team, this patented product overcomes the inherent limitations of conventional throttling devices, achieving a turndown ratio of 100:1 or greater and offering measurement accuracies of Class 1.0, Class 0.5, and other grades. It is compatible with gases, liquids, steam, and other media, making it particularly well suited for high‑pressure and high‑temperature operating conditions.

Looking ahead, automation will continue to enhance domestic flow‑measurement products, providing more cost‑effective, homegrown instrumentation solutions that drive higher‑quality development in industrial automation and contribute to the revitalization of China’s national industry.
