Badger Meter E-SeriesBadger Meter’s E-Series Ultrasonic Meters, now in expanded sizes, are designed to provide exacting flow measurement and deliver long-term, accurate meter reading for utilities. Designed specifically for water metering applications, the E-Series flowmeter uses ultrasonic transit-time technology to calculate flowrate and total consumption. The ultrasonic flowmeter is constructed with no moving parts, so mechanical wear is not a concern. The internal battery that powers the meter will last up to 20 years. The meter is accurate—within  +/-1.5 percent—regardless of water quality, sand particles, and/or pressure fluctuations. Lead-free compliant with current and future NSF/ANSI standards, the flowmeter’s stainless steel housings are available in six sizes: 5/8 inch, 5/8 inch by 3/4 inch, 3/4 inch, 1 inch, and now also 1-1/2 inch and 2 inch. A simplified one-piece electronic meter and register design are integral to the meter body for ease of installation. The flowmeter electronics are contained in a compact, encapsulated, weatherproof, and UV-resistant housing for residential and commercial applications.
