RF Card Prepayment Water Meter

We offer rf card water meter.
lxs/sr series wireless transcription intelligent valve-control wet water 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.
structure and working theory
inside the counter of water meter (mechanical part), there is one magnet embedded under the wheel pointer for 0.01 m3 of water 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 water 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.
