Ultrasonic Technology: The Gold Standard in Water Measurement
The ultrasonic water meter represents the state of the art in flow measurement. Based on the transit-time principle, it emits ultrasonic waves through the water flow to calculate velocity with exceptional precision. Unlike mechanical meters, an ultrasonic water meter contains no moving parts, eliminating all risk of wear and accuracy degradation over time.
Key Advantages of Nordia Precision Ultrasonic Water Meters
- R400 accuracy class (R800 optional) — The highest precision available on the market, compliant with ISO 4064
- Zero maintenance for 15 years — No moving parts means no mechanical wear whatsoever
- IP68 protection — Suitable for flooded pits and extreme environmental conditions
- Long-life lithium battery — Up to 16 years of autonomous operation with IoT transmission
- Multi-protocol communication — Compatible with NB-IoT, LoRaWAN, M-Bus, Wireless M-Bus, and pulse output
- Micro-leak detection — Exceptional sensitivity to very low flow rates
Complete Range: DN15 to DN300
Residential Meters (DN15 - DN25)
Our U540 model is designed for residential and small commercial metering. Compact, precise, and connected, it outperforms traditional mechanical meters while providing remote reading and leak detection capabilities.
Bulk Meters (DN40 - DN300)
The U550 and LXCY models cover the needs of distribution networks, commercial buildings, and industrial applications. Their ductile iron or stainless steel bodies ensure uncompromising durability in the most demanding environments.
Proven Results
Nordia Precision ultrasonic water meters are deployed in over 50 countries for diverse applications: drinking water distribution networks, residential and commercial sub-metering, industrial process measurement, agricultural irrigation, and smart city projects. Their R400 accuracy enables significant reductions in non-revenue water (NRW), with documented results of 30% loss reduction within the first year of deployment.
Certifications & Compliance
All our ultrasonic water meters are MID certified (Measuring Instruments Directive) and comply with OIML R49 and ISO 4064 standards. They carry CE marking and are RoHS compliant for environmental protection.
