Germany's second largest city orders Elster M100 multi-jet water meters in brass housing

ESSEN, Germany, April 13, 2011 - Elster (NYSE: ELT) announced today that it has been awarded a contract

multi-jet water meters over the next three years.

The M100 wet-dial multi-jet water meter is one of the most popular and
well-established meters in central Europe. With nominal flow rates of Qn 1.5
to Qn 15, it is EEC approved for metrological classes C (horizontal) and B
(vertical), and can be mounted in virtually any position.

It offers long life and high accuracy over a wide operating range, and
has optional pulse interfaces - a prerequisite for automated meter reading
(AMR). The product has been approved to the latest European Directive
2004/22/EC and International ISO 4064 standards.

"HWW looks forward to the installation of the M100 multi-jet water meters
from Elster as part of our metering programme," said Bernd Redmann, director,
supply chain management for Hamburger Wasserwerke.

"The M100 meets our specifications in this Europe-wide tender both for
metrology and for lead-free housing, which our corporation has chosen as a
standard for the entire city," Redmann added.

HWW is part of Germany's largest publicly owned water management company
Hamburg Wasser Group, which manages water supply and wastewater for about two
million people in Hamburg and surrounding areas. Hamburg Wasser Group had
revenues of euro 471m in 2009, manages ca. 113 million cubic meters of water
a year, and operates over a million water meters.

"This flagship order from Hamburger Wasserwerke shows the growing
confidence that we enjoy from large German municipalities, and our ability to
match or exceed their requirements," commented Johannes Gutfleisch, sales
manager of Elster's water metering business in Germany.
