body with registerface upwards; Pipeline must be Lushed before installation; The meter should be constantly full of water during
operation;
NK Suggest to Installation the water meter as:

Centralized water metering solution employs wired remote water meters paired with battery-powered (or mains-powered) concentrators, delivering a stable and efficient integrated remote meter reading solution for high-density centralized metering scenarios. The water meters utilize high-precision mechanical base meters to collect flow data, with optional optoelectronic direct-reading, non-magnetic pulse, and other electromechanical conversion methods to meet data acquisition needs across diverse application scenarios. Depending on the volume of data-loaded meters, either battery-powered concentrators (supporting 30+ meters) or mains-powered concentrators (supporting 800+ meters) can be selected to upload report data to the enterprise water management platform.
