electronic gas meter

OverviewQK6000 series gas meter is new type gas meter with CMOS system

QK6000 electroni gas meter built in COMS sensor can detect  the gas flow and convert it to analog electrical signal.  then transmit the signal tot he micro-precessor to realize the data conversion and calculations. the calculated current flow rate was stored and real flow rate is displayed.

Electronic gas meter have higth caccuracy with pressure and temperature compensation function automatically . there are no mechanical parts inside. which with low noise level as well as optional corresponding interface which is easy to be developed as prepayment meter and AMR METER.
