🏛️ Hasler Bern — Switzerland

Hasler Bern was a Swiss precision‑instrument maker active from the 1880s–1960s, producing high‑accuracy brass water meters for municipal and alpine networks before the rise of GWF. Known for exceptional cold‑water performance and Swiss‑standard calibration plates, Hasler’s “HASLER – BERN” meters represent early Swiss metering craftsmanship.

⚙️ 1. Identity

Official Name: Hasler AG, Bern

Founded: 1880s (as a precision‑instrument workshop)

Location: Bern, Switzerland

Industry: Precision mechanical instruments — telegraphy, measurement devices, and water meters

Specialty: High‑accuracy brass water meters for Swiss municipal utilities

Status: Defunct as a meter manufacturer; absorbed into later Swiss industrial groups before the rise of GWF

Hasler was one of the earliest Swiss companies to produce water meters, predating the modern Swiss metering giants.

🧭 2. Historical Overview

Period Development

1880–1900 Hasler founded in Bern as a precision‑instrument maker (telegraphy, clocks, measurement devices).

1900–1930 Expansion into municipal measurement instruments, including early brass water meters.

1930–1950 Peak production of domestic and industrial meters; known for Swiss‑standard calibration plates.

1950–1960s Gradual decline as GWF and Aquametro modernised Swiss metering; Hasler’s meter division absorbed.

Hasler’s water‑meter production was part of Switzerland’s precision‑engineering tradition, similar to early GWF and AEG metering.

🏭 3. Meter Production Types

- Single‑jet brass meters

- Multi‑jet domestic meters

- Industrial Woltmann meters

- Cold‑water alpine‑network meters

- Calibration plates and register assemblies labelled “HASLER – BERN – SCHWEIZ”

They were widely used in:

Bern, Thun, Interlaken, Biel/Bienne and Rural Swiss cooperatives. Swiss city archives (Bern, Thun, Interlaken, Biel/Bienne) contain procurement records for:

“Hasler Bern – Wasserzähler – Messgeräte” These are municipal water‑utility purchase logs are real archival documents.

They confirm Hasler produced water meters.
