Overview

The WF-YL11-2A male thread impeller flow indicator is a cost-effective visual monitoring device developed for industrial fluid pipelines. Featuring an integrally forged carbon steel body, male thread connection, and impeller indicator, it provides clear, real-time visual confirmation of medium flow status. Widely used in water supply, HVAC, industrial circulating water, and general chemical systems, it is an ideal choice for preventing system failures such as dry running and flow interruptions in cost-sensitive projects.

Key Design & Structure

1. Integrally Forged Carbon Steel Body with Anti-Corrosion Coating
Made of high-quality carbon steel, the body is integrally forged with a black anti-corrosion coating for superior strength, impact resistance, and wear resistance. It is suitable for water, oil, and weakly corrosive media, significantly extending service life and environmental adaptability.

2. Standard Male Thread Connection
Designed with universal male threads to fit DN15-DN50 pipe sizes, eliminating the need for flanges or welding. It is quick to install and disassemble, ideal for tight spaces and systems requiring routine maintenance, significantly reducing installation and upkeep costs.

3. High-Transparency Sight Glass with High-Sensitivity Impeller Indicator
Equipped with a high-strength borosilicate sight glass, the indicator features a built-in red star-shaped impeller. The impeller rotates as the medium flows, providing clear visual confirmation of flow even at low velocities, eliminating blind spots in pipeline monitoring.

4. Precision Leak-Proof Sealing
A high-temperature and aging-resistant sealing gasket between the sight glass and body ensures a zero-leakage seal, preventing leaks in various industrial media.

Core Advantages

• Cost-Effective for General Applications: The combination of carbon steel and anti-corrosion coating meets the needs of general industrial pipelines while significantly reducing procurement costs.

• Versatile Compatibility: Fits standard pipe threads in various sizes, with no additional accessories required for integration into existing pipeline systems.

• Sensitive Low-Flow Indication: The impeller design responds reliably to low flow rates, preventing false "no-flow" misjudgments and improving monitoring reliability.

• Maintenance-Free Operation: The one-piece forged body and robust design require only periodic sight glass cleaning, making it ideal for continuous industrial use.

Typical Applications

• HVAC systems: Monitoring chilled and cooling water flow to prevent pump dry-running.

• Water treatment: Visual inspection of industrial circulating water and municipal water supply systems.

• General industrial pipelines: Monitoring non-corrosive fluid pipelines in light industry and manufacturing.

• General chemical industry: Flow monitoring for oil products and weakly corrosive fluid pipelines.
