A member of the wPrime™ Series, the280W-R Residential Ultrasonic Water Meter is specially designed for domestic water metering applications where conventional water meters fail due to harsh environment, solids in water, performance degradation, magnetic vandalization or are incapable of leakage detection.
The 280W-R offers the most advanced water flow measurement by using state-of-the-art ultrasonic technology. Its flow sensor does not have any moving parts that can wear or tear, which provides a robust and accurate meter with no maintenance required.
The technical specifications of the 280W-R meet the standards for residential utility metering with Class D performance, operational temperature from 0.1°C to 60°C and safety temperature up to 85°C, as well as nominal pressure of 1.6MPa. The wide dynamic range allows for a load up to double the rating, thereby ensuring high operation security. The large LCD can display the flow total, leakage alarm, reverse flow, and more.
The meter also has a remote readout which could be configured as wired M-Bus, wMBus, RS485, LoRaWAN, LoRaLAN, NB-IoT, etc.
There are two varieties in the wPrime™ Series, 280W-R-NV water meter and 280W-R-V water meter with built-in ball valve. Forthe last version, the valve in the meter is a highly reliable ball valve that can be opened or closed remotely. This provides water company an efficient way to manage their water resources. In addition, the DN40meter can also seamlessly integrate a pressure sensor to measure flow pressure.
Robust, not impacted by water impurity. Meets the challenges of harsh environments
Spire Metering’s 280W-R Residential Ultrasonic Water Meter stands out among its competition due to its robust performance, patented sensor design, tamper-proof feature, multiple AMR / AMI options and capability to detect very low flow rates. It works reliably even when the water has particles and the environment is harsh, such as the case in Middle East and Africa. Residential installations can profit from the advantage of the wear-free water flow measurement, namely, precision, operation security and long service life.
