Structure and Working Theory:
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.
