Museum‑Grade Entry: State‑Era Chinese Water‑Meter Manufacturing (1950s–1980s)

⚙️ Identity

Official Name: Shanghai Minhang Meter Factory

Chinese: 上海闵行水表厂

Location: Minhang District, Shanghai

Active Period: 1950s–1980s

Industry: Mechanical water‑meter manufacturing

Specialty: Brass single‑jet meters for municipal water boards and rural cooperatives

Status: Defunct; absorbed into post‑1980s industrial restructuring as China modernised metering under national brands

Minhang was part of China’s state‑era industrial grid, where each district operated small workshops supplying local utilities.

🧭 Historical Overview

1950s: Founded during early PRC industrialisation; produced basic brass domestic meters.

1960s–1970s: Peak output; supplied Shanghai municipal water networks and rural cooperatives.

1980s: Decline as China adopted national metering standards and imported Japanese designs.

Post‑1980s: Workshop absorbed into larger Shanghai precision‑instrument combines.

Minhang’s industrial zone — metal shops, pump factories, and municipal depots — supported this type of workshop.
