1. Premium Product Overview
WF-YL11-033 dome type brass impeller flow sight indicator is a high-grade pipeline visual flow monitoring component engineered for heavy-duty industrial, chemical, agricultural and offshore marine working conditions. Forged integrated brass main body, hemispherical transparent dome sight window, built-in high-sensitivity red multi-blade impeller and bidirectional internal thread connection. It achieves real-time intuitive visualization of medium flow status, flow velocity and pipeline cut-off risk, effectively protecting pumps, reactors, irrigation facilities and offshore circulation systems from dry-running, cavitation and empty pipe damage. The product undergoes full pressure & corrosion aging testing, delivering stable long-cycle service in complex multi-scenario harsh working environments.

2. High-Grade Technical Specifications

- Connection Standard: BSP / NPT female internal thread, full range DN15-DN50
- Sight Window: High-strength polycarbonate hemispherical dome, impact-resistant, UV-resistant, transparent without distortion
- Sealing Assembly: EPDM/FKM fluororubber double-layer composite sealing ring, acid, alkali, salt water & oil resistant
- Indicator Core: Reinforced anti-corrosion red multi-blade impeller, ultra-low flow sensitive response
- Nominal Working Pressure: PN16 standard, PN25 reinforced marine version customizable
- Operating Temperature Spectrum: -30℃ ~ +150℃, adapt to extreme cold & high-temperature process pipelines
- Flow Structure: Full straight through full-bore design, zero flow resistance & pressure loss
- Marking: Cast integrated flow direction arrow, permanent wear-resistant identification

3. Core High-End Industrial Advantages
1. Integral forged high-density brass body, compact grain structure, excellent mechanical strength, anti-rust, anti-scaling, resistant to weak acid, weak alkali, brine, seawater and various industrial oil media, long service life without corrosion failure.
2. Hemispherical dome full-view sight glass, 270° ultra-wide viewing angle, no visual dead angle, clearly observe impeller rotation, medium impurities, foam and flow state in all installation directions.
3. Reinforced multi-blade anti-corrosion impeller, ultra-sensitive to micro flow, accurately identify low flow, cut-off, backflow risk, avoid equipment shutdown loss caused by pipeline abnormal flow.
4. Dual composite FKM/EPDM sealing system, excellent resistance to chemical corrosion, salt spray aging and high-low temperature alternating, zero leakage under long-term continuous heavy load operation.
5. Full-bore straight-through internal channel, no throttle protrusion, will not generate extra pressure drop, maintain original pipeline design flow efficiency, suitable for precision process flow control.
6. Universal internal thread two-way connection, bidirectional pipeline installation compatible, cast flow direction mark for rapid on-site construction identification, reduce engineering installation error rate.
7. Multi-scenario harsh environment adaptive design, pass salt spray, alternating cold & hot, long-term circulation aging test, reliable performance for industrial, chemical, agricultural and offshore marine long-cycle continuous operation.
8. Low maintenance industrial design, no vulnerable consumable parts, only regular simple cleaning of dome window, greatly reduce later operation and maintenance cost of engineering projects.
