Wireless Remote Radio Intelligent Natrual/Coal/ LPG Gas Meter with Steel Case
This gas meter is an unique residential gas meter designed to accurately measure volumes of natural gas, town gas liquefied petroleum gas etc. With this type you are assured of continuously good metrology and revenue protection at the same time.
Its stringent components selection meets highest demand standard in global market. I t is designed to increase customer satisfaction and save costs by providing reliable performance and long-term measurement accuracy for residential applications. With our broad range of prepaid system solutions, you can manage this type gas meter along with your STS prepaid electricity meters.
This 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.
It is certified by Chinese standards GB/T6968-1997 and Internation Standard of OIML R137.
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.
