SFK01 prepaid cool water meter is a new product researched and developed by this factory. On the base of original water meter, it makes data collection through inductor, makes corresponding data processing through CPU and displays and controls the action of valve, to attain the objective to presale of water quantity and water consumption by fee payment. It adopts special lithium battery, unique bayonet attack-proof circuit, advanced hardware and software treatment, secure and reliable IC card trend encryption mechanism, so that the performance of complete meter is secure and reliable and has the characteristics of high accuracy, low power consumption of itself, small size and convenient installation.

Functions and Characteristics:

     After the pre-received water fee is used up, automatically close the valve     Prompting water purchase. When the surplus water quantity is less than or equal to the alarmed water quantity, tick out alarmed water quantity, tick out alarm signal (close valve to give alarm while inserted card may be restored). The value of alarmed water quantity may be set flexibly before delivery in accordance with the actual need of users.     The action of valve is reliable     Having erroneous code prompting function     Having double display of mechanical graduated device and liquid crystal LCD     Measurement is accurate; no matter forward and back flowing water can be accurately measured.     Allowance ability is very strong and, even one line of dry reed pipe and valve home cock are injured, normal work can still be made.     Advance digital anti-interference circuit; unique anti-dead-machine circuit and multi-item allowance design; safe and reliable operation.     Reliable data communication, to ensure the data will never be lost or produce confused codes.     Low power-consumption design; in-built lithium battery may be persistently used for more than 5 years.     Support one card passing through function and may use one card together with watt-hour meter to make electricity and water sale management.     Having anti-magnesium function and under-voltage prompting function     Power supply: Lithium battery Technical data        accuracyB level       Li battery life 5years       operation voltage3.1V3.7V       data storage: After the electricity is lost, the data can be stored for more than 10 years.       static display of power loss15uA       nominal caliberDN15DN20DN25       executive standardCJ/T133-2001IC card cold water meter       Maximum permissible error       The low area from minimum flow(inclusive) to demarcation flow(exclusive) is±     5%, the high area from demarcation flow(inclusive) to maximum flow (inclusive) is ±2%     using environment
