WTD Wireless Remote Transmission Module

WTD Wireless Remote Transmission Module

The LXW Series CAT.1 Smart Remote Transmission Module is an intelligent module with remote communication capabilities. The product integrates metering data acquisition, data storage, remote communication, and local infrared communication in one compact device. It features ultra-low power consumption, high measurement accuracy, and stable performance.The module can be retrofitted onto compatible mechanical water meters and is widely applicable for residential, commercial, and regional water supply systems. It communicates with the management platform via the CAT.1 network for data transmission and remote command execution, while supporting non- contact local maintenance or meter reading through handheld devices.

Main Advantages
