Wireless circular gear flowmeter

Precision measurement · Wireless · High viscosity fluid metering expert

The wireless elliptical gear flowmeter employs a mechanical volumetric measurement principle and integrates industrial IoT wireless transmission technology (LoRaWAN/NB-IoT/4G) to precisely capture the volume of high-viscosity fluids through the meshing rotation of elliptical gears. The all-metal gear set combined with a non-magnetic sensor design, paired with self-lubricating nano-coating and a battery-powered wireless architecture, completely addresses issues such as pulsation interference, cable signal attenuation, and power supply challenges in the measurement of high-viscosity media like heavy oil and syrup. This provides a maintenance-free, metering-grade solution for trade handover and process control applications.

Smart turbine flow meter

Product Advantages
1. Trade-grade accuracy: ±0.5% reading (viscosity > 100 cP), 200% improvement in accuracy compared to turbine flow meters, and a 90% reduction in annual dispute losses.
2. Wireless Intrinsic Safety: Explosion-proof wireless module (Ex d IIC T6), eliminating the need for cable trenches, reducing explosion-proof zone retrofit costs by $15,000 per point.
3. High Viscosity Conqueror: Nano-ceramic gear coating resists adhesion, suitable for media with viscosity ranging from 0.1 to 100,000 cP, eliminating the risk of stalling.
4. Intelligent self-diagnosis: Real-time monitoring of gear wear/foreign object intrusion, automatic calibration when deviation exceeds 0.2%, and a 70% reduction in maintenance costs.
5. Full chain traceability: Blockchain-encrypted data storage (compliant with ISO 8000), one-click generation of flow certificates, and a 10-fold increase in audit traceability efficiency.

Core Application Areas
✅ Petrochemical Energy: Trade and delivery measurement of crude oil, fuel oil, and asphalt (compliant with API 4.2/ISO 2714 standards).
✅ Food and Pharmaceuticals: Batch quantitative control of high-viscosity raw materials such as chocolate, syrup, and glycerin (sanitary-grade 316L/EC1935 certified).
✅ Chemical Manufacturing: High-precision process blending of resins, adhesives, and solvents (corrosion-resistant Hastelloy gear sets).
✅ Agricultural Oils: Farm-end metering management of vegetable oils, pesticide concentrates, and biodiesel.
✅ Mobile Tank Trucks: Wireless measurement for tank truck loading/unloading, with GPS trajectory and flow data synchronously uploaded.

Addressing Industry Pain Points:
✦ High-viscosity fluid pulsation causing accuracy drift ✦ Outdoor wiring damaged by lightning strikes ✦ Lack of traceability data for trade disputes ✦ Gear jamming leading to production shutdowns
