Elster is one of the most important names in global metering history. Its lineage is a merger of 170+ years of European metering companies — most importantly George Kent Ltd (UK, 1838) and Elster Gas (Germany, 1848) — consolidated through ABB‑Kent in 1988, sold to Ruhrgas Industries in 2002, reorganized as Elster Group in 2005, and finally acquired by Honeywell in 2015. This also meant the Australian Davies-Shephard-Kent group came under the Elster umbrella of companies. What the new Elster Group represented 170+ years of metering heritage, with operations in 38 countries and 8,500+ employees and a

portfolio covering gas, electricity, and water metering. Elster’s water‑meter division continued the Kent tradition of:

- Volumetric piston meters (PSM, KG, V100 models)

- Woltmann (turbine) meters (H-series)

- Single‑jet and multi‑jet meters (S100, KSM)

- AMR/AMI communication modules

- Industrial flow‑measurement systems

- Expanded into smart ultrasonic metering, integrating: RF modules, Data collectors and Networked metering platforms. Elster Water Meter Group — Key Milestones
