产品概述:

Smart RF card water meter
Intelligent prepaid RF card water meter uses non-contact RF card to store water and monitor water consumption. Customers buy water at the point of sale and upload it by swiping the card. The RF card is installed in the sensing area of the water meter installed inside and outside the home to activate the valve and automatically open the water supply. During the water supply period, the built-in water meter microcomputer will automatically check and subtract the water consumption. The water meter has two alarm functions when the water is purchased. When the volume reaches the alarm value, the water meter will close the valve and stop the water supply. Users can restore the water supply through the RF card on the water meter. When the remaining water is used up, the water meter will stop supplying water completely, and the user needs to recharge the RF card.
