RF Prepaid Water Meter
Radio frequency card prepaid water meter is the new measuring instrument employing the microprocessor to realize water collection, processing, display, and reserving. It is the best choice for realizing intelligent control by most of tap water administrative bureaus, ideal for enhancing public awareness of saving water. This meter has many patents. Compared with traditional way ,it can control user’s overspend by prepaying for an RF card
≤40°C for cold water meter
≤90°C for hot water meter
Working pressure: ≤16bar
Relative humidity: ≤90%
1. RF card water meter use prepaid way to achieve the new management mode of “purchase first, then use ”.
2 .Show the different level price of the water, one card can be used for several meters.
3. Double reading display: mechanical and electronic reading
