25	7.0	3.5	0.28	0.07

10.Main export areas:Europe,Asia,North America, South America,Mid East,Oceania,Africa

Function:

1,Touchless type IC (RF) card, completely seal for against water.

2,Dual-key encryption,one card with one code.

3,One card for different meter or one card for one meter.

4,Valve will shut down for warning when the remaning water is less than the warning limitation , and the valve will open up when inserting the card. (Warning of insufficient water volume)

5,LCD will show “low power” when the remaning power is less than the warning limitation,and the user should be change the battery duly. (Warning of power shortage)

6,Data-read-back routes function:Management center can collect the data from the user card which include water consumption,battery status and the report of the human disturbance etc.

7,Small starting flow and high precision.

8,LCD: Show the volume of new purchasing,surplus and accumulative total of the water. (Warning of insufficient water volume)

Feature:

--Multi-jet, easy for maintenance;

--Magnetic drive reliable characteristic, long working life;

--Vacuum sealed register ensures the dial keep free from fog and frost, Keep the reading clear in a long term service;

-- Technical data conform to international standard ISO4064 Class B. 

Maximum permissible error:

(1) in the lower zone from q_min inclusive up to but excluding q_t is ±5%.

(2) in the upper zone from q_t inclusive up to and including q_s is ±2%;

  Hot water meter ±3%.
