   Production Descriptions: DN 15 TM CARD COLD WATE METER WITH RATES CHARGED INTO 4 DIFFERENT BLOCKS. AS WELL IS NAMED STAIRCASE PRICE WATER METER, which is one kind appliance for pre-payment of water rate

   Appliance Features:

Adopting the micro-electronics and micro- processing technology,

Prepaid, No paying, No water;

One TM card imported from USA, one water meter,

  Low-power consumption, stable performance in long-term service

for the battery.

  Suitable for the water temperature at 0℃~ 40℃ .

  In executing system, it can set a dividing point between 4 different

blocks of used water volumes by water supplier according to their

country policy., and thus have 5 kinds of water rates.

For example, when the monthly used volume of the user

doesn’t exceed the demarcation point, normal price is charged;

when it exceeds the limit point A, a higher price is charged; and if

the monthly used volume exceeds the limit point B, a much higher

price will be charged.

  It helps water supplier control using water and supervise the user

to save the water, effectively avoid happening of water waste.

ain Function Features as below,

   Pre-payment Function: Pre-payment prior to using water. Valve will be off while pre-payment use up.

   LCD Display Function: displaying the balance volume, total used volume, current purchased volume, On/Off, remind of purchasing water, using new battery, and pulling out of TM card and miss-operation etc.

   Double Sequential Access technology Function: Adopting double sequential access technology and completely resolve the problem of the measuring difference between TM card electrical meter and mechanical meter.

 Patent No. ZL 2006 2 0105260.6  for it.

Ball Valve Technology Function: Floating ball valve can avoid being fixed, controlling the lower currency, set up cleaning automatically so as to avoid full rustiness due to water scale.

Patent No. ZL 2007 2 0107935.5 for it.

Water Rates in Blocks Function: Used volume per month is measured by water meter automatically in accordance with water rates in certain steps which are set up by water supplier, top to 5 steps. More in volume used, higher in water rate.

   Balance Alarm Function:  While the balance volume reaches to the limited level, the valve will shut off for one time so as to remind the user of paying attention to the pre-payment will used up soon. User can press the enquiry key to make the appliance re-work.

Water-drop Measuring Function: Appliance system can still measure accurately the water passing volume while water is dropping. The initial fluxion is much better than the standard level.

Reimbursing Function: Balance of pre-payment will be refund to the TM card while the appliance must be replaced because of its fixed quality years, such as 6 years.

Automatic Measuring Function: Water being supplied, water meter automatically measure the passing volume into rate

Max. Volume Fixed Function: To each user, Water supplier can fix the max. used volume in system for every month or year according to their country policy.

If the purchased volume exceeds the limited level, it will be failed for purchasing.

Less Zero treatment Function: Under normal working status, the valve will shut off while the pre-payment meet to zero. If the valve happens to malfunction, the record for negative data will be made as well. It will be deducted in the next pre-payment.

   Back-check Automatically Function: Appliance can check back automatically the used volume per month of the latest 12 months.

   Data Storage Function:  All the data in the executer can be stored for over 10 years.

Password and Protection Function: Using the TM card imported from USA, automatically identifying the dada process of one card / one water meter.

Disturbance Inspection Function: while the strong magnetism is disturbing the measuring data, appliance will automatically record the date of unconventionality.

Malfunction Inspection Function: Appliance can inspect automatically the malfunction comprehensively so that technicians maintain it very easily.

Low Pressure Inspection Function: the valve will be shut off and alarm is supplied while the appliance has inspected the battery is under very low pressure. Meanwhile, it reminds user of replacing the battery.

Saving Electricity Function: Under non-working condition, consumption of battery reach zero. Long-life and high power battery can work continuously for about 9 ~ 10 years without replacing the battery.

Parameter Set Function: Parameter can be set up automatically.

                        Much easier in management for water supply.
