About R&B Instrument
For over 20 years, R&B Instrument Inc. has been dedicated to the design, manufacture, and supply of precision flow measurement instruments. Our electromagnetic, ultrasonic, and vortex flow meters serve industrial clients in water treatment, chemical processing, food & beverage, pharmaceutical, HVAC, and mining applications worldwide.
Our Story
Founded in Shanghai, China — a global hub of precision manufacturing — R&B Instrument was established with a clear mission: to provide industrial clients with high-quality flow measurement instruments at competitive prices, backed by genuine engineering expertise.
Over two decades, we have grown from a niche supplier into a recognized manufacturer serving clients across Asia, Europe, the Middle East, Americas, and Africa. Our instruments are trusted in critical applications — from pharmaceutical sterile processing to municipal water distribution networks spanning hundreds of kilometers.
What sets us apart is our application-first approach. We do not just sell flow meters — we understand your process, recommend the right technology, and support you through installation, commissioning, and beyond.
