Overview
The YUNYI NB wireless elliptical gear flowmeter uses a mechanical volumetric principle combined with industrial IoT wireless transmission (LoRaWAN/NB‑IoT/4G) to accurately measure volumes of high‑viscosity fluids by the meshing rotation of elliptical gears. An all‑metal gear set with non‑magnetic sensor design, nano‑ceramic self‑lubricating coating and battery‑powered wireless architecture reduces pulsation interference, cable attenuation and power issues, delivering a maintenance‑friendly, metering‑grade solution for trade handover and process control.

Product Advantages

• Trade‑grade accuracy: ±0.5% reading (specified for viscosity >100 cP), significantly reducing metering disputes versus turbine meters.
• Wireless intrinsic safety: Explosion‑proof wireless module (Ex d IIC T6) option removes need for cabling and related retrofit works.
• High‑viscosity capability: Nano‑ceramic gear coating resists adhesion; suitable for viscosity range 0.1 to 100,000 cP to prevent gear stalling.
• Intelligent diagnostics: Real‑time monitoring of gear wear and foreign object intrusion; automatic calibration when deviation exceeds 0.2%.
• Full‑chain traceability: Blockchain‑encrypted data storage (ISO 8000 compliant) with one‑click flow certificate generation for audit readiness.

Core Application Areas

• Petrochemical & Energy: Trade and delivery measurement of crude oil, fuel oil and asphalt (API/ISO compatible).
• Food & Pharmaceuticals: Batch quantitative control of high‑viscosity raw materials such as chocolate, syrups and glycerin (sanitary materials available).
• Chemical Manufacturing: High‑precision process blending of resins, adhesives and viscous solvents (corrosion‑resistant gear options).
• Agricultural Oils: Metering for vegetable oils, pesticide concentrates and biodiesel.
• Mobile Tank Trucks: Wireless loading/unloading measurement with synchronous GPS trajectory and flow data upload.

Addressing Industry Pain Points

• Accuracy drift caused by pulsation in high‑viscosity media.
• Outdoor wiring damage and cable signal attenuation.
• Lack of traceable data for trade disputes.
• Gear jamming leading to production stoppages.
