Product Description
Features:
High-tech integrative product
Uses advanced wireless transmission technology
Through microelectronic control circuits, it converts pulse signals of traditional mechanical meter into electrical signals
Then metering data is transmitted to background platform through GPRS network automatically, or it can be collected by a handheld wireless unit from outside of houses and after that downloaded to computer through USB port
Applied to metering of gas volume flowing across gas pipe and meter reading from outdoor or through remote transcription
Structure and working theory:
Inside counter of gas meter (mechanical part), there is one magnet embedded under wheel pointer for 0.01m3 of gas and two reed switches beside each side of wheel
Each time pointer goes circle, one group of two pulses is generated to represent 0.01m3 of gas being calculated
Pulses are converted to digital signals and recorded as metering data based on pre-set program
Then metering data can be transmitted to concentrator or hand-held unit
Mechanical performance complies with GB/T69681997 diaphragm gas meter national standard level B
