The approved measuring range of 1600:1 marks the first time this
exceptional level of performance has been achieved from a Woltmann type water

With a range of important features and its innovative measuring
technology, the H5000 is ideally suited for billing or water distribution
applications. A new rotor design combined with proven sensor technology
maximizes its measuring range.

A single measuring element improves sensitivity, durability and maintains
its useful life even at the highest flow rates. With low-flow capabilities
similar to combination meters, the H5000 provides a metrological performance
that ensures accurate measurement of minimum night flows.

The H5000 meter has an advanced electronic register which includes
integrated communications covering a range of industry standard outputs
compatible with common AMR/AMI systems and data-logging equipment.

"The approval of a range of H5000 meter sizes under European Directive
2004/22/EC recognizes the substantial investment and expertise of Elster's
development team and is the latest example of the innovation our customers
expect from Elster," commented Tim Gabriel, senior vice president of
operations for Elster's global water business.

"With a measuring range of 1600:1, the H5000 offers customers a solution
that provides accurate water measurement in support of both commercial
billing and network applications. It also simplifies meter selection and
helps to provide reliable connectivity for Smart Metering and other telemetry
devices," Gabriel added.
