Wireless communication water metering management system program
 
About the program
This system is composed of wireless ultrasonic water meter (or other wireless terminal meter), wireless data collector, wireless data concentrator and data center. The construction and maintenance of this program is very simple and can be widely used in a variety of complex environments.
 
Program Features
Wireless transmission system, no wiring connection and simple construction.
Data collector comes with data storage function.
Simple structure, as long as customer set user information in data collector by software, system
Debugging can be completed.
 
Program Requirements
  Terminal meter: A variety of meter with wireless communication function. Such as ultrasonic water meter, valve control ultrasonic water meter, pipe net smart control valve, pipe net ultrasonic water meter., etc.
   Wireless data collector: using wireless 433 communication collect terminal meter data in the downlink. And using wireless 470 communication transfer data to GPRS data concentrator on the uplink.
   Wireless data concentrator: use wireless 470 communication collect data in wireless data collector on the downlink and use GPRS communication to transfer data to data center on the uplink.
    Data center: server installed with reading management software and datasheet software should be equipped with fixed IP.
