Durable Brass Body Multi-Jet Water Meter DN20 (20 mm)
- Ergonomic Viewing: 45° slanted dry dial ensures easy, fog-free reading.
- High Precision: Class B (R100) accuracy catches ultra-low 13.3 L/h flows.
- Extreme Protection: IP68 waterproof rating for reliable submerged operation.
- Tamper-Proof: Integrated anti-magnetic shield secures your billing data.
- Easy Setup: Standard DN20 190mm body with G3/4B BSP threads.
Advanced Multi-Jet Design for Reliable Measurement
Engineered for superior precision, this velocity-type multi-jet water meter guarantees consistent performance for residential and commercial water tracking. It features an innovative 45° slanted dry dial coupled with a highly responsive magnetic drive transmission, ensuring the display is exceptionally easy to read from various angles without bending or straining. Designed specifically for standard horizontal installation, the hermetically sealed register completely isolates the internal counting mechanism from water. This prevents condensation and fogging, ensuring the dial remains crystal clear over years of service.
Rugged Construction and Certified Protection
Built to withstand challenging environments, this device boasts a maximum IP68 protection class, making it completely dustproof and highly resistant to prolonged water submersion. It operates flawlessly under a robust MAP16 pressure class and is tailored for cold water applications up to 30°C (T30 temperature class). Furthermore, the meter strictly complies with global ISO 4064 standards, providing utility companies and property managers with certified assurance regarding its structural integrity, safety, and long-term operational reliability.
