I. Overview:

This type of terminal (CKZD-1FY) is mainly used for collecting the base number of large-caliber water meter and pressure of pipeline network. It transmits data to the server remotely through GPRS, and completes the monitoring and management of water supply, pipeline network status and other information by supporting background management software. It is widely applicable to large-caliber water meter monitoring in the field and other power-free areas.
