Application:
.Measuring the total volume of cold(hot) water passing through the pipeline.
Feature:
.RF water meter user pre-paid way to achieve new management mode which is "Pay first,then use";
.Show the different price level of the water ,one card can used for several meters;
.Double reading display:mechanical and electronic;
.Unique battery protection;
.Stable performance,wide application;
.Low power consumption and long working life;
.Vacuum sealed electronic parts conform to IP67;
.Anti-Magnetic function;
Characteristic:
1.Its measurement and other performance reach to GB/T778.1-2007<Cold Water Meter >and CJ/T133-2012<IC Card Cold Water Water Meter>Construction Ministry  standard;
2.One card to one water meter :Applying faultless system,ensure  the safety of the date of user ;
3.Anti-fake function :Using advanced encryption technique ,ensure the automatic recognition  on any other  illegal IC card which is not the permanent card this meter used;
5.Anti-theft function :When there is ferromagnetic measurement-interference signal ,it will shut down the valve automatically until the ferromagnetic signal disappear ,avoid the ferromagnetic stealing the water;
6.Low voltage protect function:When inner battery at low voltage ,it will shut down the valve automatically ,remind the user to inform relatively department changing the battery as soon as possible;
7.Anti rust-dead function :It will automatically open the valve twice per month,avoid valve has the rust-dead situation after long non-using,promote working stability.
