Overview
The YUNYI LoRa wireless elliptical (circular) gear flowmeter is a mechanical volumetric meter designed for reliable metering of high‑viscosity fluids. It combines an all‑metal gear set with a non‑magnetic sensor, self‑lubricating nano‑coating and industrial IoT wireless transmission (LoRaWAN / NB‑IoT / 4G) in a battery‑powered architecture. The design targets trade handover and process control where pulsation, cable routing and power availability challenge conventional sensors.

Product Advantages

• Trade‑grade accuracy: ±0.5% reading for viscosities >100 cP, improving on typical turbine meter performance for heavy media.
• Wireless intrinsic safety: explosion‑proof wireless module (Ex d IIC T6) enabling cable‑free installations in hazardous areas.
• High‑viscosity capability: nano‑ceramic / nano‑coating on gear surfaces resists adhesion across 0.1–100,000 cP, reducing gear stall risk.
• Intelligent self‑diagnosis: real‑time monitoring of gear wear and foreign object intrusion with automatic calibration when deviation >0.2%.
• Full‑chain traceability: blockchain‑encrypted data storage (ISO 8000 compliance) and one‑click generation of flow certificates for audits.

Core Application Areas

• Petrochemical & energy: trade and delivery measurement of crude oil, fuel oil and asphalt (where applicable, compliant with API 4.2 / ISO 2714).
• Food & pharmaceutical: batch dosing and quantitative control of high‑viscosity ingredients such as chocolate, syrups and glycerin (sanitary 316L / EC1935 options available).
• Chemical manufacturing: high‑precision process blending of resins, adhesives and solvents (Hastelloy gear options for corrosive media).
• Agricultural oils: metering vegetable oils, pesticide concentrates and biodiesel.
• Mobile tank trucks: wireless loading/unloading measurement with synchronous GPS trajectory and flow data upload.

Operational benefits / Industry pain points addressed

• Reduces accuracy drift caused by pulsation in viscous fluids.
• Eliminates need for vulnerable outdoor wiring by using wireless transmission.
• Provides audit‑ready traceability to reduce trade disputes.
• Minimizes downtime risk from gear jamming through anti‑adhesion coatings and wear/foreign object detection.
