Overview
YUNYI 4G wireless elliptical gear flowmeter is a mechanical volumetric meter using meshing elliptical gears to accurately measure volumes of high‑viscosity fluids. It integrates industrial IIoT wireless transmission (LoRaWAN / NB‑IoT / 4G) with a battery‑powered wireless architecture to enable maintenance‑free, trade‑grade measurement for custody transfer and process control.

Product Advantages

• Trade‑grade accuracy: ±0.5% reading for fluids with viscosity > 100 cP; demonstrated accuracy gains vs turbine meters and reduced annual reconciliation losses.
• Intrinsic‑safe wireless: explosion‑proof wireless module Ex d IIC T6, eliminating wired cabling for the communications unit and lowering retrofit costs in hazardous zones.
• High‑viscosity capability: nano‑ceramic anti‑adhesion gear coating minimizes build‑up; suitable for media from 0.1 to 100,000 cP, reducing gear stall risk.
• Durable all‑metal geartrain with non‑magnetic sensor and self‑lubricating nano‑coating for extended service life in heavy/oily fluids.
• Intelligent self‑diagnosis: real‑time gear‑wear and foreign‑object detection; automatic recalibration when deviation > 0.2%, lowering maintenance effort.
• Full‑chain traceability: blockchain‑encrypted data storage (ISO 8000 compliant) enabling one‑click flow certificate generation and improved auditability.

Core Application Areas

• Petrochemical & Energy: custody transfer and delivery measurement for crude oil, fuel oil, asphalt (applicable to API 4.2 / ISO 2714 scenarios).
• Food & Pharmaceutical: batch dosing and quantitative control of viscous raw materials such as chocolate, syrups, glycerin; sanitary options (316L / EC1935) available.
• Chemical Manufacturing: high‑precision blending of resins, adhesives and solvents; Hastelloy gear options for corrosive media.
• Agricultural Oils: metering of vegetable oils, pesticide concentrates and biodiesel.
• Mobile Tank Trucks: wireless loading/unloading measurement with GPS trajectory and synchronous flow data upload for mobile operations.

Addressing Industry Pain Points

• Reduces accuracy drift from pulsation in viscous fluids through positive‑displacement measurement.
• Eliminates dependency on vulnerable external cabling by using intrinsic‑safe wireless modules.
• Provides tamper‑evident, auditable data to speed dispute resolution in custody transfer.
• Minimizes downtime from gear jamming via anti‑adhesion coatings and real‑time diagnostics.
