E-Series® Meter Cold Water Stainless Steel Ultrasonic Meter Model E-25, E-35 and E-55 - NSF/ANSI Standard 61 Certified, Annex G The electronic Badger Meter E-Series® meter utilizes ultrasonic and solid-state technology in a compact, totally encapsulated, weatherproof, and UV-resistant housing for residential and commercial applications. Electronic metering provides information and data not typically available through traditional, mechanical meters and registers, such as rate of flow and reverse flow indication, and eliminates measurement errors due to sand, suspended particles and pressure fluctuations. Offered in four sizes and lay lengths, the E-Series meter features: • Minimum extended low-flow rate lower than typical positive displacement meters. • Simplified one-piece electronic meter and register that are integral to the meter body and virtually maintenance free. • Sealed, non-removable, tamper-protected meter and register. • Easy-to-read 9-digit LCD display – presents consumption, rate of flow, reverse-flow indication, and alarms. • Digital or industry standard encoder protocol. The E-Series Meter is available with a wired lead, 308 in-line connector or fully prewired to ORION® and GALAXY® AMR/AMI endpoints. It is also offered with the Itron® in-line connector, in-line connector with pit endpoint, or prewired to an Itron remote endpoint. Applications Use the E-Series meter for measuring potable cold water in residential, commercial and industrial services. The meter is also ideal for non-potable, reclaimed irrigation water applications or less than optimum water conditions where small particles exist. The E-Series meter complies with applicable portions of ANSI/ AWWA Standard C700 and NSF/ANSI Standard 61, Annex G. There is currently no AWWA standard that specifically addresses ultrasonic meters for residential applications. Operation & Performance As water flows into the measuring tube, ultrasonic signals are sent consecutively in forward and reverse directions of flow. Velocity is then determined by measuring the time difference between the measurement in the forward and reverse directions. Total volume is calculated from the measured flow velocity using water temperature and pipe diameter. The LCD display shows total volume and alarm conditions and can toggle to display rate of flow. ESM-T-01-EN (2-12) In the normal temperature range, the E-Series “new meter” consumption measurement is accurate to: • ±1.5% over the normal flow range • ±3.0% from the extended low flow range to the minimum flow value Construction E-Series meters feature a stainless steel, lead-free meter housing, an engineered plastic and stainless steel metering insert, a metercontrol circuit board with associated wiring, LCD, and battery. Wetted elements are limited to the pressure vessel, plastic/ stainless steel metering insert and the transducers. The electronic components are housed and fully potted within a molded, engineered plastic enclosure, which is permanently attached to the meter housing. The transducers extend through the stainless steel housing and are sealed by O-rings. The metering insert holds the stainless steel ultrasonic reflectors in the center of the flow area, enabling turbulence-free water flow through the tube and around the ultrasonic signal reflectors. The metering insert’s patented design virtually eliminates chemical buildup on the reflectors, ensuring long-term metering accuracy. Meter Installation The meter is completely submersible and can be installed using horizontal or vertical piping, with flow in the up direction. The meter will not measure flow when an “empty pipe” condition is experienced. An empty pipe is defined as a condition when the flow sensors are not fully submerged. Technical Brief
