双方向式水道メーター盗難防止装置

Bi-Directional Water Meter Anti-Theft Feature

Bi-Directional Water Meter, or Multi Directional Water effectively prevents water theft, Even if users tamper with the water meter and install it in reverse, the BMAG Bi-Directional Water Meter can still function accurately. They ensure the rational use and management of water resources.

It accurately records actual water consumption, overcoming the issue of reversed readings caused by incorrect installation in traditional water meters. Additionally, the application of smart technology increasingly incorporates remote monitoring and data transmission capabilities, making water management more efficient and transparent.

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
