Full Name: RF card (contactless IC card) Prepaid Water Meter
Model No.: LXSIC~15-25CA
Application: Used for measuring the volume of consumed water passing through the pipeline and water fee management & control
Features: Low power dissipation, attack resistance, large register capacity, convenient operation and reliable characteristic
Tech. Standard: ISO4064-2005, GB/T 778.1-778.3-2007, JJG 162-2009
---Prepay water charge via water purchasing/rechargeable card, prepayment before usage; Eradicate phenomena of water charges arrears.
---LCD capable to display the current purchased volume, remaining volume, accumulative consumed volume, facilitate user queries; Maintenance personnel and background management system can inspect and analyze the data which is read-out by using the inspection card.
---Valve will shut automatically under circumstances of battery under voltage, power supply interruption or external magnetic field interference.
Remind & Alarm
---Timely remind or alarm in the situations of battery under voltage, remaining volume insufficiency, misoperation or magnetic disturbance.
---Automatically collect and analyze the monthly actual consumption situation of every water user, suit the operating department's management convenience
---Adopt anti system halted circuits & valve anti-blocking patent design, prevent dysfunction of water meter actuating mechanism
---Adopt fully sealed design, perfect water proof performance, suitable for damp & humid installation sites
---Meter inner preset with self-checking function, check valve's flexibility and avoid lithium battery dormancy.
---User's data could be saved for over 10 years, no data loss in case of battery empty or cut off.
--- For the same user that holds multi RF cards for water, electricity, gas meters or more RF water meters, All-in-one-card management & control is feasible
---Able to conduct measuring methods in water volume or amount of money; In the case of amount measuring, flat rate tariff multiple tariff and ladder prices are feasible
---On administrative department's request, ladder prices for different segment charging are feasible to be set, facilitate administrative department to execute "ladder price" policy easily
