RF Card Prepayment Flow Water Meter (LXSIC-15CA~LXSIC-25CA)

Application: Measuring the volume of hot potable water passing through the pipeline
Features: RFID Technology, low power dissipation, water proof, simple operations, stable quality
Technical Standards: GB/T 778.1~778.3-2007,JJG 162-2009
Main Functions:
Control Function
---Prepay water charge via water purchasing/rechargeable card, prepayment before usage; eradicate phenomena of water charges arrears.
Inquiry Display
---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.
Protection Function
---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.
Automatic Statistics
---Automatically collect and analyze the monthly actual consumption situation of every water user, suit the operating department's management convenience
Anti-blocking
---Adopt anti system halted circuits & valve anti-blocking patent design, prevent dysfunction of water meter actuating mechanism
Water Proof
---Adopt fully sealed design, perfect water proof performance, suitable for damp & humid installation sites
Automatic Maintenance
---Meter inner preset with self-checking function, check valve's flexibility and avoid lithium battery dormancy.
Data Retention
---User's data could be saved for over 10 years, no data loss in case of battery empty or cut off.Extended Functions:
One Card
--- 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
Measuring Methods
---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
Ladder prices
---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 Items Technical data Water Temperature 30-90ºC Working Pressure 1.0MPa Head Loss 0.063MPa Power source One built-in lithium battery Working voltage 3.6V Working current <40mA Quiescent current <3μA Quiescent power dissipation <3.6Vx3μA/10.8μVA Electromagnetic compatibility Accords with GB/T 17626.2/17626.3/17626.4 Valve Performance Under pressure of 0.02 and 1.0MPa respectively, permanent flow rate(Q3), reliable open and close, flexible operation, no abnormal conditionNominal Dia.Metrological AccuracyPermanent Flow Q3Q3/Q1Q2/Q1Min.
