As metering accuracy becomes ever more essential to business performance, water utilities are exploring the latest metering technologies. Badger Meter now offers electronic E-Series Ultrasonic Meters that use ultrasonic transit time technology to calculate flow rate and total consumption.

The meters measure flow using high-frequency sound waves, according to John Fillinger, director of utility marketing. They are able to measure ultra-low flows, such as those caused by leaks in households or business establishments, so that when used in the context of an advanced metering infrastructure (AMI), they can help utilities detect those leaks and alert property owners to make repairs.

Solid-state design eliminates mechanical wear that can degrade metering accuracy in the long term. “As traditional mechanical meters wear, they tend to slow down and record lower-than-actual flows, to the detriment of utility revenue,” Fillinger says. “These meters ensure that utilities record all the flow and capture all revenue, and do so throughout the meter’s life span.”

The E-Series meters have no moving parts; an internal battery provides power for up to 20 years. Designed for potable water applications, the E-Series meters deliver accuracy within ± 1.5 percent over their normal flow range.

The meters are lead-free compliant with NSF/ANSI standards. Electronics are held in a compact, encapsulated, weatherproof and UV-resistant housing for residential and commercial applications. The stainless steel housings are available in 5/8-inch, 5/8-by-3/4-inch, 1-inch, 1 1/2-inch and 2-inch sizes (for the last four the company holds UL certification). E-Series are the first electronic meters certified under newly published UL Subject 327B for residential fire service applications. They are also suited for potable water and reclaimed water applications. 800/876-3837; www.badgermeter.com.
