The overall structure of an ordinary mechanical water meter is composed of five major parts: watch case, pressure cover, watch glass, movement, and fittings. The case is usually made of cast iron, while the smart one is made of copper. In ordinary water meters, water flows from the bottom to the top, and the water flowing into the lower ring chamber of the water meter enters the upper ring chamber through the filter bottom net to drive the gears to rotate to realize the water meter reading. The movement is mainly divided into upper and lower three layers, the key is the impeller of the lower layer, only the upper pointer and dial can be seen from the watch glass. Its advantage is that it is cheap and uses no electricity.
The smart card water meter is a new type of water meter that uses modern microelectronics technology, modern sensing technology, and smart IC card technology to measure water consumption, perform water data transmission and settlement transactions. This is a big improvement compared to the functions of ordinary water meters that only have flow collection and mechanical pointers to display water consumption. And the smart card water meter is an electronic display, which effectively prevents the unclear reading caused by the rust in the case or the stain on the glass of the ordinary water meter. Secondly, because its data transmission and transaction settlement are carried out through the IC card, it can be realized by The change of the staff's door-to-door watch charge to the user's own payment.
Therefore, the smart card water meter can make users know whether there is still water in time, and it is convenient to operate. Relatively speaking, smart card water meters are easier to serve customers than ordinary water meters, better summarize information, and reduce manpower.
