⭐ Founding of AMCO (AMERICAN METER COMPANY)

Founded: 1886 by James Brown and William Clow

Location: Philadelphia, Pennsylvania, USA AMCO (American Meter Company) was a major U.S. water‑meter manufacturer known for PD, multi‑jet, and Woltman meters.

It became Elster‑AMCO after acquisition by Elster Group, then became part of Honeywell in 2015.

The AMCO brand no longer exists, but its meter designs remain in production under Honeywell/Elster. Early products focus (1886–1920)

AMCO originally produced gas meters, not water meters.

AMCO entered the water‑meter market in the 1930s–1940s and know for; - positive displacement (PD) meters

- multi‑jet meters

- Turbine meters

AMCO was considered a mid‑tier U.S. manufacturer, smaller than Rockwell/Sensus but respected.

AMCO (1980s–2000s)

In 2004 the company was eventually acquired by Elster Group, a major German metering conglomerate.

Elster re-organised AMCO into Elster‑AMCO Water, LLC.

During this era, AMCO’s product line expanded to include:

- C700 PD meters

- M190 multi‑jet meters

- H4000 Woltman meters

- AMR/AMI encoder registers

In 2015 Honeywell Acquires Elster/Amco.

AMCO ceased to exist as an independent brand.

The AMCO meter designs (C700, M190, H4000) continues in production, but they are no longer branded “AMCO”. The HWM.Museum has a few Amco water meters in its collection.
