LoRa Brass Smart Wifi Domestic Water Meter
The system consists of LoRa wireless remote valve control water meter, data concentrator and operation management platform. The lora brass smart wifi domestic water meter is transmitted or received via radio (current frequency 470-510 MHz, 865-868 MHz) to the concentrator, and the concentrator transmits data via the SIM card network or accepts commands to connect to the operating platform. Thereby, the water consumption of the water meter is viewed on the platform, and the function of the water meter switch valve is controlled.
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.
Compoment
Lora water meter,concentrator,Cloudy platform,Reapter and handle reading tools
Service
· Quality Gurantee: Water meter for 1 year;
· Support install guide & test in site;
· Date sheet can be sent to other management system easily.
Brief introduction of LoRa wireless water meter
1.Battery: To keep battery for easily replacement;
2.Direct Reading Sesor: To read the current display of water(Photoelectric Sensor or Angular Displacement Sensor);
3.Base Water Meter: To calculate current quantity of using water;
4.Valve Control:Remote valve control(optional);
5.Forced Trigger: To wake up water meter when it needs to be debug;
Characteristics of LoRa wireless water meter
1.This model uses Direct Reading Technology which can make sure data accuracy is 100%;
2.The position of vavle is designed on the water outlet so it will have less influence for reading accuracy;
3.Electronic reading device will not affect the accuracy of original water meter;
4.The product is with IP68 ingress protection level.
Software advantages
1. Short distance communication,so the power consumption is low.
2.The administrator can actively send the instruction of meter reading or on-off valve to the water meter form the platform through the concentrator to achieve the purpose of real-time control.
3.The cost of use is low,only concentrator need use sim card.Water meter no need.
Work process
Lora system
Lora water meter system are transmit and recevie the signal form watermeter and concentractor via Lora signal.Concentrator collect water meter reading to Platform and send the command form platform via 2g/3g/4g or internet signal
