Precision Measurement for Residential Applications
This DN15 volumetric water meter utilizes advanced piston displacement technology to deliver exceptional low-flow sensitivity and measurement stability. Boasting a highly accurate Class B (R400) rating and a remarkably low starting flow of just 2.08 L/h, it precisely captures even the smallest water usage, such as minor leaks or drips. This makes it an ideal choice for apartments and light commercial properties looking to reduce non-revenue water. Fully compliant with ISO 4064 standards, this meter ensures reliable billing accuracy while maintaining a minimal pressure loss of ≤0.063 MPa. As a premium offering from DZS WATER METER, a trusted manufacturer of high-precision solutions, it guarantees stable, long-term performance.
Robust Construction and Future-Proof Design
Built for demanding field environments, this volumetric water meter features a dry dial with a hermetically sealed register, ensuring the display remains completely clear and free from condensation over its lifespan. The rugged design achieves an IP68 protection class, safeguarding the internal mechanisms against flooding, dust, and moisture in harsh conditions. Measuring 165mm in length with standard G3/4B threads, it allows for straightforward horizontal installation. Most importantly, this unit is engineered to be AMR-ready, enabling seamless future upgrades to smart, automated remote reading networks without the need to replace the entire plumbing setup.
Key Features & Advantages:
- Volumetric Piston Technology: Delivers a superior R400 measuring range and a minimal minimum flow rate (Q1) of 6.25 L/h, drastically reducing unmeasured water loss.
- Hermetically Sealed Dry Dial: Provides lasting clarity and IP68 waterproof reliability, protecting the register from humidity and harsh operating environments.
- AMR-Ready Capability: Readily integrates with remote reading modules, allowing utilities to easily upgrade traditional metering to modern IoT networks.
