Specifications

1.Clear dial reading; 2.Fully sealed design; 3. water proof; 4.anti-ultraviolet, 5.Perfect performance in outdoor or underwater

Function: Measuring the volume of cold potable water passing through the pipeline
Technical Standards: ISO4064-2005, GB/T 778.1~778.3-2007, JJG 162-2009

Main Functions:

 

Water& Dust Proof--IP68
---Adopt fully sealed design, perfect water proof performance, suitable for damp & humid installation sites, perfect for outdoors and underground usage

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

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
