- Commodity name: SPH-ZNMD-B-B End-of-Line Water Testing Device Central Controller
A two-bus technology is used between the end-of-line test device and the system. Both communication and power supply are handled by the bus, requiring only a single pair of twisted-pair cables, thus saving on cable usage.
1. A two-bus technology is used between the device and the end-of-line test water device; both communication and power supply are handled by the bus, requiring only a single pair of twisted-pair cables, thus saving on cable usage.
2. The entire device system features real-time monitoring of water pressure, water flow status, valve status, and other functions.
3. It features bidirectional operation capabilities for both local and host control—allowing valve opening and closing either manually or electrically from the local site, as well as from the host system.
4. The host real-time monitoring system connects to all intelligent end-of-line water testing devices and provides alarm information.
5. The host can set installation location information for each terminal.
6. The host system records all operations in real time, leaving a trace at every step, making it possible to track and trace back.
