1. Product Overview
WF-YL11-21H straight barrel impeller flow sight indicator is a new upgraded visual pipeline flow monitor independently developed by Weifeng Tech. It adopts integrated straight barrel stainless steel forging body, dual female thread connection, top large-view borosilicate sight glass and built-in red star impeller. Real-time visual observation of fluid flow, flow rate and pipeline cut-off, effectively avoid pump dry-running, empty pipe damage. Widely used in HVAC circulating water, pure water treatment, chemical oil, food pharmaceutical sanitary pipeline, hydraulic cooling oil circuit.

2. Core Technical Specifications

- Sight Window: High-pressure resistant borosilicate glass
- Sealing System: Double layer fluorine rubber O-ring anti-leakage seal
- Indicator Component: Red star-shaped sensitive impeller
- Nominal Working Pressure: PN16, PN25 (customizable high pressure)
- Operating Temperature Range: -20℃ ~ +180℃
- Structure Feature: Straight full-bore barrel, no flow resistance

3. Product Core Advantages
1. Integrated straight barrel forging stainless steel body, smooth inner wall, no dead angle, anti-corrosion, rust-proof, meet food & pharmaceutical sanitary standards.
2. Full straight through full-bore design, no flow blocking protrusion, zero extra pressure loss, will not affect original pipeline conveying efficiency.
3. Large top-view sight window, 180° wide viewing angle, clearly observe impeller rotation state and fluid impurities.
4. High-sensitivity star impeller, tiny fluid flow can drive rotation, accurately judge low flow and pipeline water shortage.
5. Double fluorine rubber sealing structure, excellent pressure and temperature resistance, long-term operation without water seepage and leakage.
6. Straight barrel compact integrated design, small overall volume, save installation space, suitable for narrow equipment built-in pipeline.
7. Maintenance-free design, no vulnerable spare parts, only regular wipe the sight glass for long-term continuous production operation.

4. Wide Application Industries
1. HVAC central air conditioning cooling circulating water system
2. Industrial pure water, water purification equipment pipeline monitoring
3. Lubricating oil, weak corrosive chemical fluid transportation pipeline
4. Food, pharmaceutical factory sanitary grade raw material conveying pipeline
5. Industrial hydraulic equipment, machine tool cooling oil circuit flow observation
