Netafim Water Meters Paddle Wheel - IRT Flanged

Accurate, Durable Flow Measurement for Irrigation and Wastewater Applications

The Netafim IRT Paddle Wheel Water Meters are engineered for precise flow measurement in irrigation, wastewater, and recycled water systems. Designed specifically for moderate to dirty water conditions, the IRT’s paddle wheel mechanism allows a free water passage with minimal head loss—ensuring accurate readings, even when suspended solids or debris are present.

Available in sizes ranging from 80mm to 250mm (3"–10"), these flanged meters offer versatile, reliable performance for small to large-scale agricultural and municipal water systems.

Netafim IRT Paddle Wheel Water Meters (80-250mm Flanged), the precise and reliable solution for measuring water flow in your irrigation system. Designed for accuracy and durability, these water meters provide essential data to optimize water usage and ensure efficient irrigation practices.

The Netafim IRT Paddle Wheel Water Meters feature a paddle wheel mechanism that rotates in response to the flow of water. This mechanism accurately measures the volume of water passing through the meter, allowing you to monitor and manage your water usage effectively.

With a flanged design and available sizes ranging from 80mm to 250mm, these water meters are suitable for a wide range of irrigation systems, from small-scale installations to larger agricultural projects. The flanged connection ensures secure and leak-free installation, providing a reliable and long-lasting solution.

FEATURES

• Paddle Wheel Technology: Positioned at the top of the water passage to prevent clogging and allow unimpeded flow measurement.
• High Accuracy: Maintains ±2% accuracy across a wide flow range—even in systems with high levels of suspended solids.
• Low Head Loss: Hydraulic design ensures minimal pressure drop while maintaining flow precision.
• Flanged Connections: Standard BS Table D flanges for easy installation and secure system integration (other flange standards available upon request).
• Sealed & Fog-Free Register: Hermetically sealed glass lens protects the stainless steel register from moisture or condensation.
• Self-Flushing Bearings: Bearings are continuously flushed during operation to reduce solids build-up and prolong service life.
• Optional Output Signals: EV (Volume) and EF (Flow Rate) electrical outputs available for remote monitoring and integration with the Netafim Dialog® automatic reading system.
