About F&V GROUP

F&V GROUP is a global industrial measurement company committed to delivering innovative, energy-efficient solutions for temperature, pressure, flow, and level applications. Established in 2021, the group unites strong international expertise with localized manufacturing and service capabilities.

Our journey began in 2011 with the founding of FVLUOKY in Wales, UK—a brand built on precision engineering and technological excellence. Over the years, FVLUOKY became a trusted name in industrial measurement across international markets.

To better serve the Asia-Pacific region, Fuyi Intelligent Instrument (Shanghai) Co., Ltd. was established in 2019, introducing FVLUOKY’s product lines to China with localized assembly, testing, and innovation. Fuyi products are fully certified (ISO, CE, TS, CPA) and tailored to regional industry needs.

With the formation of F&V GROUP in 2021, our brands were strategically integrated to accelerate global growth. By 2024, F&V had become a leading force in China and began expanding its footprint to international markets—bringing high-performance, sustainable measurement solutions to customers worldwide.

At F&V, we combine global innovation with local insight—driven by a commitment to quality, sustainability, and customer success.
