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.
Overview
Large diameter ultrasonic water meters are high-tech devices that help measure the volume of water flowing through large pipelines. They use ultrasonic technology to detect the velocity and volume of water and convert those measurements into data that can be used for billing, monitoring and conservation purposes.
Features
·Material:cast iron/ductile iron
·Applicable scene:home main pipe/apartment main pipe/domestic residential water supply main/leak/treatment plant/domestic residential/agriculture/irrigation/agricultural/irrigation /ground/aquaculture/commercial/general household/residential building/industrial/school/potable
·Technical data conform to international standard ISO 4064.
·communication:rs485 modbus/GPRS
·fitting:Pressure sensor/battery/lcd display/reading device/data logger/Flange set/liquid turbine/user interface unit
Working principle
The meter comprises the quality temperature sensor ,the flow sensor and the calculator. The temperature sensor to measure the temperature of water and the flow sensor to measure the volume of water that flow through the pipelines by the transit time difference.
The two data is sent to the calculator after being collected, the consumption water quantity is worked out, stored and indicated on the LCD finally.
