GS series
wireless transcription intelligent gas meter is high-tech integrative
product. This series meter uses advanced wireless transmission
technology. Through microelectronic control circuits, it converts the
pulse signals of traditional mechanical meter into electrical signals.
Then the metering data is transmitted to background platform through
GPRS network automatically, or it can be collected by a hand-held
wireless unit from outside of the houses and after that downloaded to a
computer through USB port.
This
product is applied to metering of gas volume flowing across gas pipe,
and meter reading from outdoor or through remote transcription.
Inside the
counter of gas meter (mechanical part), there is one magnet embedded
under the wheel pointer for 0.01 m3 of gas and two reed switches beside
each side of the wheel. Each time the pointer goes a circle, one group
of two pulses is generated to represent 0.01 m3 of gas being calculated.
The pulses are converted to digital signals and recorded as metering
data based on pre-set program. Then the metering data can be transmitted
to a concentrator or hand-held unit.
