Steel Material Smart RF Communication Remote Reading and Control
Gas Meter
The CA768 is not only an unique residential gas meter applied to
accurately measure volumes of natural gas, town gas liquefied
petroleum gas etc, but also AMR / AMI facility with data exchange
features. The revenue protection and data mangement can be realized
by utilizing this meter type in any severe circumstances,
delivering high performance measurement at an economical price.
Its die-cast steel case with convoluted diaphragms enables smooth
operation and long life . The chamber drum is selected with
European standard materials with substantial durability. This new
type bridges the former steady but standalone dumb metering with
up-to-date real time data acqusition and interaction of smart
metering. Another outstanding feature is that this meter is
integrated with latest STS standard and operates with 20 digits'
token code. It offers utmost convenience and security to both
consumers and service providers.
