🔧 Industrial Maintenance Engineer Review

⭐⭐⭐⭐⭐ James Peterson - Oil & Gas Extraction Facility
"We’ve been using the Yunyi Intelligent Digital Flow Meter in our offshore natural gas operation since February 2025, and it’s been a game-changer. The high-precision sensors deliver consistent readings even under high pressure and temperature fluctuations. Installation was handled by our instrumentation team, and after calibration, it’s been running flawlessly for 7 months. The digital display is clear and easy to read on-site, and we appreciate the battery-powered design—no need for external power in remote locations."

🏭 Chemical Processing Plant Technician Review

⭐⭐⭐⭐⭐ Elena Martinez - Chemical Processing Plant
"Purchased the Pro Model in November 2024 for monitoring solvent flow in our reactor lines. After 8 months of continuous use, I can confidently say this is the most reliable flow meter we’ve used. The customizable display allows us to monitor volume and flow rate simultaneously, which has improved our batch control accuracy. The stainless steel body shows zero signs of corrosion, even with aggressive chemical exposure. Worth every penny for critical applications."

💧 Water Treatment Operations Manager Review

⭐⭐⭐⭐☆ David Lin - Municipal Water Treatment Plant
"We integrated three of the Advanced Models into our filtration system in January 2025. The RS485 Modbus connectivity made integration with our SCADA system seamless. Real-time data has helped us optimize pump scheduling and reduce energy use. Only downside is the initial setup calibration—it took longer than expected and required vendor support. However, once running, performance has been excellent. Battery life is holding strong at 6 months with no signs of degradation."

⚙️ Industrial Automation Consultant Review

⭐⭐⭐⭐⭐ Thomas Reed - Industrial Automation Specialist
"As a consultant working across multiple sectors, I’ve specified flow meters for over a decade. The Yunyi Pro Model, which I recommended to a client in April 2024, stands out for its 30% higher precision and extensive customization. We’re using it in a compressed air distribution network, and the adjustable settings for different pressure ranges have been invaluable. The compact digital display updates in real time with minimal lag—up to 20% faster than older analog units. For any facility upgrading legacy systems, this is a top-tier choice."

🛠️ Field Service Technician Review

⭐⭐⭐⭐☆ Anita Patel - Field Maintenance Contractor
"Installed the Base Model at two small-scale natural gas metering stations in December 2024. After 7 months in the field, durability is impressive—no issues with vibration or weather exposure. The battery-powered operation is ideal for remote sites without power access. Only limitation is the basic display; it doesn’t support temperature compensation out of the box, which would’ve been helpful. Still, for standard flow monitoring, it performs reliably and is much easier to operate than older mechanical meters."
