20mm Long battery life Lora water meter brass body china
The Lora water meter can realize remote monitoring, data collection and transmission, meter reading, automatic statistic and other functions.Our company's water meters are sold to the United States, India, Morocco, the Philippines, Vietnam, Bangladesh and other countries, so please believe that our export experience is very rich.We have a strict quality inspection system, and the water meter will only be shipped after repeated factory inspections.
AMI SYSTEM INTRODUCTION SIMPLE IS SMART
System structure diagram as follows
· Server send commands to the data concentrator through network;
· Concentrator transforms the received commands into radio signal and send the signal to the water meters;
· Water meters respond and execute the commands accordingly;
·Water meters deliver the result or data back to the management center as per the original route after the actions finished.
Service
· Quality Gurantee: Water meter for 1 year;
· Support install guide & test in site;
· Date sheet can be sent to other management system easily.
