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
·Ultrasonic water meter's intelligent measuring instrument is consist by the temperature sensor , flow sensors and calculators.
·Could provide important application and data for many applications in the pipeline.
·Ultrasonic water meter is suitable for application environments requiring high range ratio(Q3/Q1)and forward and reverse metering.
·Calculator used sensor and through the time difference to collect temperature differences and sound waves to complete accurate measurement of water flow. And can provide important application and data for many applications.
·Features long service time and high accuracy
·Double-flange dry-type digital water meter, used in industrial pipelines, suitable for high pressure environment, can choose whether to install pulse output
·With remote transmission system software to support reading and monitoring
·Provide a complete software metering and charging solution
·Bulk Water Meter
Automatic leak measurement

Working principle
The working principle of a large diameter ultrasonic water meter is based on the use of ultrasonic technology to measure water flow rates. The meter consists of two ultrasonic sensors placed on opposite sides of the pipeline, and which inject ultrasonic waves into the flowing water.
