Increased Performance. Enhanced Data.

E-Series G2® Ultrasonic inline meters for residential applications have no moving parts, which leads to improved reliability, increased performance and maximized revenue.

  • Ease of Use. Display reports consumption, rate of flow, reverse-flow indication, temperature, alarm conditions and firmware versions. The meter has field programmable registration and an hourly internal logging capacity of 160 days of data.
  • Drive Revenue Gains. Offers long-term sustained accuracy within ±2% and extended low flow accuracy within  ±5%. With high measurement accuracy, especially for low-flow conditions, these meters can help utilities limit unaccounted-for water and capture additional revenue over the course of their 15-year battery life.
  • Advanced Data. Temperature data and alarms report at the meter and through ORION® Cellular endpoints and BEACON® SaaS for increased visibility into water distribution systems.
