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

GPRS wireless water meter belong to high-tech smart water meter, using of advanced wireless transmission technology. It transmission metered information of conventional mechanical water meter to cloud server via GPRS.

GPRS AMR water meter is a combination of GSM wireless access technology and Internet packet switching technology.

Automatically read the metering data via wireless remote network and control the close / open of the valve, and is also able to transfer the data to the back-office system (data center) after reading the meters by wireless handset reader.

Water meter is used for home,garden,commercial,general ,building,municipality

GPRS intelligent water meter has security seal and valve control, uses battery powered,automatic pulse read display

Features

·Connection method is threaded connection
·Non-contact water meter
·Material:Brass body,Brass interface
·Accuracy:class b,r100,r80
·waterproof level:IP68
·Fitting:connctor,Icd display,pulse output,valve control,strainer,reading device,data logger,adapter,actuator,base table,battery operated,connection fittings,coupling,pointer,components,calibrator,counter,register
·Reading Frequency:The reading mode of GPRS water meter system is passive reading. The default reading frequency of water meter is 3 days. Reading frequency 1 time per day is acceptable.
·Module with automatic data storage function when power down arises, assuring the data won’t lost when power down.
·Using GPRS transfer mode that can drastically extend the communication.
·The module uses of deep dormancy time design, it is able to completely close the wireless module during the deep dormancy time period(not in operation during night time ), which drastically help reduce the power dissipation;
·Wide area network, no installation distance and water meter quantity limit.

Application
GPRS system is suitable for the installation of scattered environment, such as rural residential, factory,irrigation and other industries.

Work process
GPRS water meter transmit data and receive command the from water meter via 2g signal to Platform.

Software advantages
1. Simple installation, the installation method is the same as the mechanical water meter, no wiringis required;
2.The signal transmission is stable without being affected by the communication distance.

3. Short online time, it will go online for 30S to ensure the service life of batteries.
