1862: The beginnings
Neptun is founded in Wrocław
Diehl Metering can look back on a long history that goes back into the early years of industrialisation: In 1862, Neptun is founded in Wrocław as a foundry producing fittings for water and gas installations – this is also where the world’s first Woltman bulk water meter is developed and produced in 1895.
Neptun becomes Hydrometer
In 1912 the company is renamed as Hydrometer Breslauer Wassermesserfabrik. Even today, industry experts still consider this name a guarantee of high-quality metering and reading technology.
From Wrocław to Ansbach
The company takes a significant step in 1951: the Middle Franconian town of Ansbach becomes the new headquarters of Hydrometer. The relocation provides Hydrometer with space, technological opportunities and strategic prospects for developing into a company of international standing. Approximately 480 development, production and sales employees still work at the three hectare site today.
1970: The start of a successful story
1,000,000 water meters
The 1,000,000th water meter rolled off the production line in Ansbach in 1970, heralding the start of a successful decade. A continual increase in orders leads to the necessity for extensive production plant building.
1989: Flow meter sets a milestone
New technological standard
An innovation developed in-house sets the new technological standard for the years to come: Hydrometer receives the PTB accreditation for an electronic flow meter. Furthermore, the 4,000,000th Bavarian produced water meter is celebrated.
1991: The Hydrometer Group is created
Production plant opens in Apolda
Following the reunification of Germany, in 1991 Hydrometer GmbH founds a production plant in Apolda for the mass production of domestic water meters in order to meet the increasing demand for high-quality meters. In the same year, a testing laboratory for residential and individual domestic water meters was certified in Apolda.
Sappel (France) and Mirometr (Poland) are incorporated
1998 sees the strategic expansion of the Hydrometer Group: Renowned French company Sappel and the Polish subsidiary Mirometr are taken over. Diehl Metering S.A.S., formerly Sappel, constructs and produces water meters and radio-based reading systems.
EWT (Austria) is incorporated
The strategic expansion continues in 2001 with the incorporation of Austrian company ELIN Wasserwerkstechnik GmbH as well as the Hungarian water meter manufacturer MOM. The Vienna-based market leader for water meter technology EWT is a pioneer in the radio-based reading sector. The Mátészalka-based measurement technology specialist MOM has for decades been the market leader in Hungary and holds a strategically key position with regard to East European markets.
SAPPEL do Brasil is founded in Brazil
