SECK - Model LoRaWAN -Intelligent Water Meter System

Advantage of LoRaWAN System

1、Ultra-long distance communication,measured stable communication distance more than 5Km between the Gateway device and LoRaWAN Water Meters.

Adopting LoRa modulation technology,set IOT wireless communication experience for redio frequency[RF]to calibrate,the measured steady communication distance>5km,perfectly solved the small amount of data from the problem for ultra-long distance communication.

2、Ultra-low power consumption and support for 3 power saving modes.
Combined with multiple power consumption optimization techniques,such as multi-stage adjustable,multi-stage dormancy and air awakening,it can realize ultra-long distance transmission in ultra-low power consumption,which has obvious advantages in battery power supply application.

3、Ultra high acceptance sensitivity,to a staggering -142dbm.
LoRa modulation technology has a unique spectrum amplification processiong for signals,and the receiving sensitivity is up to a staggering -142dbm,which is a good for the highly reliable meter reading industry.

4、Large network capacity,flexible networking and low cost.

5、The LoRaWAN network can be connected to tens of thousands of nodes,which can be flexibly added and reduced according to the household water meter.The network expansibility is pretty good.The system operating cost is lower cause the free communication between the LoRaWAN Water Meters and Gateway.

1. Unique thick film technology :This type water meter adopts modular split structure.It greatly reduces the maintenance cost of products.This technology is the patented technology of SECK.
2. The sensor is made of rare precious metals such as palladium / silver / ruthenium and so on. It can guarantee the long-term stability and reliability of the sensor.
3. No need to initialize the meter readings when installing new meters or replacing with new ones.
4. Refrain from the error when collecting data, and avoid the problems of sending signals by mistake due to rounding of the character wheels.
5. Simple setup: the initial installation just needs to set up the cell network ID, the wireless frequency.Do not need to set the initial value of the water meter, network path and so on.
6. Combined with a PC system, to establish a remote automatic meter reading system, really realize the automatic meter reading
7. The cost of running and maintenance is low: the Lora wireless network works in a free wireless frequency range.Only a small amount of GPRS communication fee is required for the concentrator to communicate with the main station of the server；The product is designed by modular design.When the water meter needs to be repaired, only the water meter is replaced, and the LoRa wireless communication box can be reused.
8. System use micro power design: using micro power design, the average power consumption is less than 20uA. in the case of one meter reading every day, a 4AH, 3.6V lithium sub battery works for 7 years.
9. Data storage includes information of water meter marking (water meter number, type, etc.), water accumulation, working state and so on.
