What is a Copper-Sealed Water Meter?

A Copper-Sealed Water Meter is a type of water meter in which the register is vacuum-sealed and protected by a copper housing.

This technology helps to:

• Completely eliminate fogging

• Prevent moisture from entering the register

• Avoid internal scale formation on the glass surface

• Maintain clear readability for many years

It is considered one of the most advanced technologies used in high-quality water meters today.
