Detailed Product Description

OVERVIEW - AMR System

AMR Definition:
AMR stands for Automatic Meter Reading.
AMR is the remote collection of consumption data from customers' utility meters.
AMR can use power-line, telephony, RF, cable communication technologies.
AMR provides electric, water, gas and heat utilities the opportunity to increase operational efficiency, improve customer service, reduce data-collection costs and quickly gather critical information that provides insight to company decision-makers
