Overview

The WF-YL11-06 wafer type impeller flow indicator is a high-pressure, flange wafer-style visual monitoring device developed for industrial pipelines. Featuring a precision-cast 304/316 stainless steel body, wafer flange connection, transparent sight window, and impeller indicator, it allows clear observation of medium flow conditions. Widely used in water supply, HVAC, chemical processing, food & pharmaceutical, and general industrial systems, it is a key component to prevent system failures such as dry running and flow interruptions.

Key Design & Structure

1. High-Quality Stainless Steel Body
The body is precision-cast from high-quality 304/316 stainless steel with a passivated surface treatment for superior corrosion and wear resistance. It is suitable for water, oil, and weakly corrosive media, with no risk of rust or contamination, meeting hygiene requirements for food and pharmaceutical applications.

2. Wafer Flange Connection
The four-bolt wafer flange design fits directly between standard flanged pipes, eliminating the need for welding or threading. It is quick to install and disassemble, suitable for DN15-DN50 pipe sizes and ideal for high-pressure, high-stability industrial pipeline scenarios.

3. Borosilicate Glass Sight Window with Double Seal
The high-strength borosilicate glass sight window is paired with food-grade fluororubber O-rings for double sealing. With excellent pressure and temperature resistance, it allows 180° clear observation of medium flow, impeller rotation, and impurities, eliminating blind spots in pipeline monitoring.

4. Built-In Impeller Indicator System
A multi-blade red impeller inside the tube rotates as the medium flows, providing clear visual confirmation of flow even at low velocities. The impeller speed also roughly indicates the flow rate, intuitively reflecting the pipeline's operating status.

Core Advantages

• High-Pressure Wafer Design: The wafer flange connection offers high strength and excellent sealing, suitable for medium and high-pressure pipeline applications with no leakage risk.

• Full-Bore No-Pressure-Loss Design: The straight-through structure maintains the pipe's full bore without additional pressure drop, ensuring no impact on medium delivery efficiency.

• Sensitive Low-Flow Indication: The multi-blade impeller responds reliably to low flow rates, preventing false "no-flow" misjudgments.

• Maintenance-Free Operation: The precision sealing structure and robust design require only periodic sight glass cleaning, making it ideal for continuous industrial use.

• Versatile Compatibility: The combination of a stainless steel body and corrosion-resistant seals ensures long-term resistance to water, oil, and weak acids/alkalis, suitable for various complex working conditions.

Typical Applications

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

• Water treatment: Visual inspection of circulating water and pure water systems.

• Chemical and light industry: Monitoring weakly corrosive fluids and oil pipelines.

• Food and pharmaceutical industries: Hygienic flow monitoring for clean media pipelines.

• High-pressure industrial systems: Flow status observation in hydraulic and high-pressure pneumatic systems.
