NWE ULTRASONIC WATER METER
Description
Overview
NWE Smart Water Meter integrates the State of the art Ultrasonic sensing technology with Low-power RF-based communication to offer the best solution for Domestic as well as Commercial metering requirements. Its fully integrated design with no moving parts ensures extremely long maintenance free operation periods. With virtually no obstruction along the flow of water, the head pressure loss is almost negligible, reducing overall delivery costs. A low starting flowrate and very high measuring accuracy allows for detection of leaks and tampers, thereby helping minimize water loss.
Coupled with Analogics’ suite of RF-based handhelds and Meter Data Management SW, it is the most comprehensive and integrated solution with minimal or no manual intervention.
