Precision Measurement for Residential & Light Commercial Use
This DN20 Multi-Jet Dry Dial Water Meter is engineered for reliable, long-term performance in horizontal pipeline installations. Built on a velocity-type measuring principle, the multi-jet design distributes water flow evenly across the impeller, delivering consistently stable and accurate readings throughout its service life. Its hermetically sealed, 45°C dry dial register keeps the display permanently fog-free and fully legible, even in damp or submerged environments.
Built for Durability and Reliability
The meter carries an IP68 protection rating, making it fully submersible and highly resistant to dust and water ingress — ideal for underground or outdoor metering applications. A built-in anti-magnetic protection mechanism guards against tampering and external magnetic interference, ensuring billing integrity. The magnetic drive transmission eliminates direct mechanical contact between the measuring chamber and register, significantly extending the meter’s operational lifespan with minimal maintenance.
Key Features & Advantages:
- ISO 4064 Class B (R100) Accuracy: An impressive dynamic range ratio of R100 means the meter accurately captures both very low and peak flows, minimizing revenue loss from undetected consumption.
- Wide Flow Range: With a starting flow as low as 13.3 L/h and a permanent flow rate of 4.0 m³/h, it handles the full spectrum of typical residential demand.
- High-Resolution Reading: Measures down to 0.05 liters, enabling precise leak detection and consumption monitoring.
- G3/4B BSP Threaded Connection: Standard DN20 / 190mm face-to-face length ensures straightforward drop-in installation and compatibility with widely used pipework.
- Robust Pressure & Temperature Ratings: Rated at MAP16 and T30, suitable for standard residential water supply systems worldwide.
