ISO 4064 Multi Jet Water Meter Bi-Directional MTW-E2

ISO 4064 Multi Jet Water Meter MTW-E2

ISO 4064 Multi Jet Water Meters are internationally certified, ensuring assured high-quality water meter by ISO standards.

Two-Way Water Meter Working Principle:

The Bi-Directional Water Meter is an improved version of the dry-type water meter. It features an enlarged outlet diameter and parallel channels for both the inlet and outlet. This design allows the Two-Way Water Meter to function correctly regardless of installation direction, enabling users to interchange the inlet and outlet freely.

利点：

Anti-Theft: Even if the user changes the direction of the meter, the pointer will not reverse, preventing the meter reading from reversing at the root
Economic Benefit: Protecting the interests of water companies

アプリケーションシナリオ：
