Why Neptune R900® System Endpoints? A single radio frequency unit, Neptune’s endpoints feature an interleaved, high-power, 1-watt fixed network message that reduces infrastructure costs while allowing reading in any mode – walk-by, mobile, or fixed network – without separate reading systems, site visits, or any type of reprogramming or reconfiguration. Available in both wall and pit mount configurations, Neptune endpoints greatly improve access to meter readings, and deliver detailed consumption information as well as alerts for leak or backflow, helping your utility more proactively identify and resolve customers questions.
