Overview

The WF-YL11-2K ferrule type impeller flow indicator is a highly sensitive visual monitoring device developed for precision fluid pipelines and instrument systems. Featuring an integrally forged 304/316 stainless steel body, double ferrule connection, and high-sensitivity impeller sight window, it provides real-time, intuitive observation of medium flow conditions. Widely used in laboratory equipment, instrument pipelines, high-purity fluid transmission, and small industrial circulation systems, it is a key component to ensure stable operation of precision systems.

Key Design & Structure

1. Integrally Forged Stainless Steel Body
Made of high-quality 304/316 stainless steel, the body is integrally forged with a passivated surface treatment for superior corrosion and wear resistance. It is suitable for pure water, reagents, and weakly corrosive media, with no risk of rust or contamination, meeting hygiene requirements for high-purity and clean applications.

2. Double Ferrule Quick Connection
Designed with standard double ferrules to fit precision instrument tubes (such as 6/8/10/12mm outer diameter), eliminating the need for welding or threading. It is quick to install and disassemble with excellent sealing performance, ideal for compact laboratory and equipment internal pipelines, significantly reducing installation and maintenance 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 star-shaped impeller. The impeller rotates as the medium flows, providing clear visual confirmation of flow even at low flow rates, eliminating blind spots in pipeline monitoring.

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

Core Advantages

• Superior Corrosion Resistance: Stainless steel construction resists corrosion from water, reagents, and weak acids/alkalis, offering a longer service life than carbon steel alternatives, suitable for precision and clean applications.

• Versatile Compatibility: Fits standard ferrule connections for various instrument tube sizes, with no additional accessories required for integration into existing precision pipeline systems.

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

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

Typical Applications

• Laboratory and instrument equipment: Flow monitoring for experimental pipelines, small reaction devices, and analytical instruments.

• High-purity fluid transmission: Visual flow monitoring for pure water, reagents, and clean media pipelines.

• Small industrial circulation systems: Observation of media flow in small cooling systems, hydraulic systems, and pneumatic systems.

• Instrument supporting pipelines: Flow monitoring for instrument front-end and sampling pipelines to prevent equipment failure due to flow interruption.
