Museum‑Grade Entry: Polish Water‑Meter Manufacturing (1920s–1950s)

⚙️ 1. Identity

Official Name: Polskie Zakłady Wodomierzy

Translation: Polish Water‑Meter Works

Location: Łódź, Poland

Active Period: ~1920s–1950s

Industry: Domestic & industrial water‑meter manufacturing

Specialty: Brass single‑jet and multi‑jet meters for municipal waterworks and textile‑industry facilities

Status: Defunct; absorbed into post‑war state industrial consolidation (Zjednoczenie Przemysłu Precyzyjnego)

Polskie Zakłady Wodomierzy was one of Poland’s earliest dedicated water‑meter manufacturers, serving both municipal networks and the massive textile industry of Łódź.

🧭 2. Historical Overview

Period Development

1920–1939 Founded as a precision‑machining workshop; produced domestic brass meters for Łódź and surrounding towns.

1939–1945 Wartime disruption; limited production under occupation; some meters supplied to municipal networks.

1945–1955 Post‑war expansion; integrated into state‑controlled industrial supply; produced VEWIN‑style registers for export.

Post‑1955 Absorbed into larger Polish precision‑instrument combines; water‑meter production discontinued.

Łódź’s industrial ecosystem — textile mills, metal workshops, municipal waterworks — made it a natural hub for early Polish metering.
