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/T778.1-2007and CJ/T133-2012Construction 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

 Dimensions and weight:

Installation and maintenance:

1.The diameter of water meter is selected according to pipeline and flow rate ,not suitable for hot water;

2.Installation position need to avoid  exposure ,frozen,pollution ,flooding .

3.Horizontal water meter be installed horizontally. For easily disassemble and assemble ,please make words face upward , and make the direction of the arrow on the case  in the same direction of flow;

4.New pipeline must clean up the stone, sand and other debris

before install the water meter ,to avoid the water meter breakdown .

5.For collect measurement ,the faucet must higher than water meter ;the straight pipe connected to inlet of water meter must not less than 10D,the straight pipe connected to outlet of water meter must not less than 5D,D short for  meter size.

6.Water meter should not be directly connected to the pipe ,the connections between the meter and

pipeline should adopted connecting pipe, gasket, coupling nut ;when assembly and disassembly,

must not forcibly pull hard ,to avoid unnecessary wrenching of water meter case which affect the

normal operation of the water meter

7.Meter above is prohibited put any items. Pay attention to moisture-proof and damp-proof ,strictly prohibit water droplets penetrate into meter controller which would damage control system and affect the normal use of the water meter .

8. Battery: 6 years
