About Dayu Electronics

Fuzhou Dayu Electronic Technology Co., Ltd. was established in 2008, a high-tech enterprise specializing in ultrasonic measurement technology R&D and manufacturing.

Headquartered in Fuzhou, Fujian Province, we have an in-house R&D team and modern production facilities, committed to delivering high-precision, high-reliability ultrasonic sensors, level meters, flow meters, and marine acoustic equipment to global customers.

Built on fundamental acoustics principles, Dayu has established a full-chain in-house R&D system spanning transducers, hardware, software, materials and structures — one of the few companies in China capable of closing the entire ultrasonic technology loop without application boundaries.

With 17 years of technological expertise, Dayu holds multiple national patents. Our products are widely used in industrial automation, hydrology and water resources, environmental monitoring, and marine exploration.
