Thank you for choosing the LXSZ-15E~20E, Intelligent IC Card Water Meter .Before use the water meter ,please read the instruction carefully ,for using the water meter correctly .
 
This water meter is type of Non-touched (Radio Frequency Card) .It mainly used for measuring the total quantity of water passing through the pipeline,for prepaid function .The user pay the water fee to management department,the management department write the quantity of purchased water into the IC card,when user plug the IC card into the water meter(Touched type) or approach to the sensor area (Non-touched type ),
 
the purchased water will automatic record into the water meter .Later on,the water meter will automatically open the valve to provide water. The water meter will decrease the usable water following the used water of the user .Together with the shortage of usable water ,it will send the warning of purchasing the water ;When using up the water, the water meter will automatically shut down the valve, user need to repurchasing the water to open the valve.
 
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
