Products Description
An Introduction
The HAC-WR-S electronic backpack is a low-power product that integrates measurement collection and communication transmission. It is compatible with all wet multi-flow meters with standard bayonets and induction coils from Sensus . Abnormal conditions such as backflow, water leakage, and battery undervoltage can be monitored and reported to the management platform. The system cost is low, the network maintenance is convenient, the reliability is high, and the scalability is strong.
