Product Detail
Prepayment, incremental water price, mechanical and LCD display ;External battery placement, pilot valve, waterproof socket,

  Advantages

External battery placement and easy to replace IC card socket is designed to be waterproof, so the entire meter can stand sprinkling.  The meter can work normally even when the meter housing is being sprinkled for less than 2 hours 

    3.The pilot valve is immune from scale deposit and water pressure, and is therefore more secure, stable and reliable. 

Product standards and main parameters 

1)        Product technical standards: CJ/T133-2001 and GB/T778.1 

2)        Maximum error tolerance of base meter conforms to the requirement of the GB/T778.1B-level meter.  

3)        Pressure resistance intensity: 1.6MPa, 15min

Basic Functions

 

Display

Functions

 

Functional Display

Limited current input, current input, remaining water volume, cumulative water volume, payment, on/off valve, wrong card, battery replacement and attack signal 

Data Display

Maximum cumulative water volume:  9999.9m3.

Control Functions

 

Water Consumption  Control

Close valve reminder when the remaining water volume reaches alarming water level; open valve with cards and valve will close automatically when water is all used up; user can use card to purchase water, open valve and control water supply.

Low voltage

Close valve reminder when battery voltage is lower than the pre-set value; users can open valve with card. The valve will be completely closed if the battery is not replaced within 24 hours.

Self-checking function 

When power on, check the circuit automatically to judge if meter is in normal status or not.

Anti-theft and anti-shear

Valve closes automatically and attack signal displayed when the signal-sampling wire is cut.  It can only be repaired by administrator not the user. 

Moisture-proof Socket 

Moisture of socket does not affect meter reading.  It will constantly detect if the IC card slot is normal or not. 

Self- protection of battery & valve

Meter opens and closes valve automatically once a month.

Input volume limitation

The meter sets the highest water storage volume.  When the sum of purchased water volume & the remaining water volume is larger than the pre-set value, no more input is allowed. 

Over zero processing

When the valve breaks down, it does not affect normal measurement and over-zero measurement processing. The user card will transmit relevant information to the host or upper computer accordingly. 

Pulse sampling moisture-proof

When the sampling circuit board and the sampling line become moist, signal input and output are still normal without data loss and increase in power consumption. 

Self-testing function 

The meter can perform self-testing to detect engine failure, storage device mistakes, wrong card, wrong write-back, etc.  

Routine Cycle Check 

The meter will begin cycle check of up to 10 times once in every 5 minutes when the valve is shut down due to attack.  It will resume to normal status when the attack stops.

Usage Functions

Data Recycle 

When meter is damaged and needs replacement, the transfer card into the broken meter to read and retrieve data. The data will be transferred to the new meter when the data transfer card is ed into the it

Initialization 

Insert the initiating card to clear all the information inside the meter and set all the parameters. 

Inspection card 

Use the inspection card to check the system when the meter runs abnormally.

Card replacement 

Replacement card is available when user loses the user card. 

Incremental Water Rate

 

The user card can register freezed water volume, and count the incremental water consumed.
