AMR system, remote gas meter. Volumetric type. M-bus communication. Optional controlling valve.

Remote gas meter reading system:

Volumetric gas meter with M-bus communication for AMR system.

Power supplied by cable line based on low dissipation design.

Standby power supply can works over 5 years afer power off .

M-Bus technique explanationM-bus is a kind of bus structure of public utility measure instrument named Meter-Bus,or M-

bus.The principle of work is data transmission based on modulation demodulation technique on

DC power line.M-bus dedicated chip is embedded into meters and concentrator and data

translated by two wire cable.Technical characteristics:1.Distant and reliable communication based on high speed stable communication rate.2.Discretionary cable laying ways of serial type,star type and cross type are acceptable.3.Non-polarity parallel line and twisted pair are used for cable laying.4.Anti-interference based on isolation communication equipment,constant-current electric

current loop communication system.5.Auto-Login,admissible for multiple devices and multiple communication protocol,this system

is easy to be expanded.6.Powered by M-bus cable,low quiescent power drain,this system is suitable for meters that

needs of outside power supply.
