Smarter Measurement, Stronger Performance

E-Series G2® Ultrasonic meters provides reliability and accuracy for maximized revenue.

Features

  • Ease of Use. Meter displays and reports consumption, rate of flow, status indicators and alarm conditions. The meter is field programmable and has data logging capacity for 160 days of hourly data extraction directly from the device.
  • Drive Revenue Gains. Offers long-term sustained accuracy within ±1.5% and extended low flow accuracy within ±3%. 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 20-year battery life. No moving parts, eliminates the cost of meter maintenance.
  • Advanced Data.  When equipped, Pressure Sensors provide data and alarms captured at the meter and report through ORION® Cellular endpoints and BEACON® SaaS for increased visibility into water distribution systems.

Market Applications

  • Customer Water Usage

    Municipal water utilities are responsible for sourcing, treating and distributing water while adhering to stringent quality standards. These applications demand the highest level of accuracy, flexibility and reliability. Our water meters and flow monitoring technologies, coupled with powerful analytics software, provide end-to-end solutions that optimize revenue, conserve water and enhance end customer confidence in their water utility.

    As the leader in cellular AMI, our products feature robust communication technology to reliably deliver data that utilities need for proactive management of water services.

  • Drinking Water Treatment

    Drinking water treatment facilities have the critical job of providing a safe, high-quality drinking water supply. Complex operational processes demand the highest flow meter accuracy and reliability, as well as long-term stability and a low cost of ownership. Water treatment solutions that deliver real-time data and historical reads with alarms for measurements outside of typical operation help utilities meet the challenge of increasing compliance levels. When utility customers have access to real-time water quality, flow and pressure data, they can more easily protect treatment assets and provide opportunities for process optimization.
