‌High-Performance Flow Monitoring for Critical Applications‌

The ‌G3/4 Paddle Wheel Flow Switch‌ delivers precision flow monitoring for water pumps, heating systems, and industrial fluid control. Engineered to operate across 100-220VDC with 1.5A contact capacity, this sensor ensures reliable performance in automotive, HVAC, and manufacturing environments.

‌Technical Specifications‌

• ‌Flow Range‌: 1.5–30 L/min (±2% accuracy)
• ‌Voltage‌: 100–220VDC (compatible with universal power supplies)
• ‌Contact Configuration‌: SPDT (N.O/N.C), 1.5A resistive load
• ‌Material‌: PP/POM housing, stainless steel paddle wheel (IP65-rated)
• ‌Temperature Resistance‌: -20°C to +120°C (suitable for high-temperature fluids)
• ‌Connection‌: G3/4 threaded port, customizable wire length (350mm standard, extended options available)

‌Design Advantages‌

1. ‌Smart Flow Detection‌

   • Paddle wheel design minimizes pressure drop while maintaining sensitivity to low-flow conditions (1.5L/min threshold).
   • Integrated Hall effect sensor ensures contactless signal transmission, reducing mechanical wear.

2. ‌Industrial-Grade Durability‌

   • Corrosion-resistant PP/POM construction withstands chemicals, oils, and high-viscosity fluids.
   • Reinforced shaft bearings extend lifespan in high-vibration environments.

3. ‌Universal Electrical Integration‌

   • Wide voltage input (100-220VDC) eliminates need for external transformers.
   • Isolated relay contacts prevent back EMF damage to control systems.

‌Typical Applications‌

‌Why Choose This Flow Switch?‌

• ‌Plug-and-Play Installation‌: Pre-calibrated for common fluids (water, glycol, light oils).
• ‌Customization‌: Optional M12 connectors, 24VAC/DC variants, and explosion-proof housing.
• ‌Compliance‌: CE, RoHS, and UL94-V0 certifications (request test reports for full details).
