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.

 

Brief introduction
LoRa wireless water meter adopts advanced wireless transmission technology, which transforms information of conventional mechanical water meter into electrical signal that stored by micro-electronics control circuit. It is able to automatically read the metering data via wireless remote network and control the close and open of the valve.

Benefits
·With anti-magnetic interference function.
·With the battery voltage detection function.
·Module with automatic data storage function when power down and up, which assuring the data won’t lost when power down.
·With 7 layers 8 types of price to support market demand.
·The joint of the RF module and the base meter uses the integrated structure with built-in antenna, which reducing the damage of antenna during the process of installation;
·Using LoRa transfer mode can drastically extend the communication distance.
·The module use of deep dormancy time design is able to completely close the wireless module during the deep dormancy time period (not in operation during night time ), which drastically help to reduce power dissipation;
·Whole circuit board uses of ultra low power consumption design, power suuply by high capacity lithium battery and battery life over 6 years;
·Set up the metering devices by the handset reader and check the original data and data from meter reading;
·AMI function that supports the system is able to control of valve opening or closing on real-time.

FREQUENTLY ASKED QUESTIONS

Water meter

1. How long is the battery life?

Using ER26500 batteries with a capacity of up to 9000 mAh and the frequency of reading meters once a day, the battery life can reach up to 8 years.

2. Waterproofing grade?

At present, the LoRa wireless water meter adopts the technology of full encapsulation and sealing. It uses the silicon gel packaging circuit board part, and the battery plug and socket is also sealed to reach the IP68 protection level.

3.Can your product run underwater?

This product can be soaked in water, but soaking in water will affect the stability of signal transmission, because the signal transmission in water will be greatly affected

4. Can you make Lora ultrasonic valve-controlled water meter?

No, because the built-in valve will have a greater impact on the stability of the ultrasonic measurement, the higher the frequency of the switch valve, the greater the impact on the accuracy of measurement.

5. If the valve cannot be closed or opened, how can it be found and handled?

If the valve is blocked by sand and gravel flowing into the pipeline, the program in the water meter will try to execute the action of the on-off valve within 40S.

If the valve can not be switched normally, the water meter will give up the instruction and return the failure data to theplatform.

On the platform, the relevant information of the water meter can beviewed for the convenience of the management.

Communication and serve platform

1. Does the GPRS wireless water meter need a concentrator or a collector?

No, because the GPRS wireless water meter uses the existing GPRS communication tower for data transmission, which is similar to the mobile phone signal transmission.

2.How many Lora water meter can be connetted into one concentrator?

At present, the maximum carrying capacity of one concentrator is

500 pieces.

Considering the actual installation density of the community, generally speaking, it will be much lower than this number.

3.What data can the platform collect from water meters?

At present, our platform can collect accumulative flow rate, battery voltage, upload time on the water meter, and ultrasonic LoRa can also collect instantaneous flow rate.

4. How does the concentrator transmit data?

The concentrator needs 220V power supply and uses GPRS to transmit data to the PC platform.

5. How about the transmission distance?

The distance of LoRa data transmission is mainly affected by the actual installation environment. In relatively spacious transmission environment, the transmission distance can reach 1000-1500 meters.

Generally speaking, the concentrator will be installed at the commanding heights of the community.

GPRS water meter Under the GPRS signal, the data uploaded by GPRS water meter is not affected by distance.

6.How do you know that the water meter is out of order and there is no data to return?

First, we can check the alarm function on the platform to see that the water meter has no data return, and then check the installation environment to see if there is obvious damage, and can use the initiative to trigger the water meter to be on-line way.

7. Is the platform free? Can it pay in advance?

It is free, and the administrator can pre-charge the amount of money
