This water meter is used to measure the total volume of the water passing through the pipeline, suitable for one-way and nonpulse flow. Smart IC card (cold water, hot water, pure water) meter is the new measuring instrument using the latest international micropower and very large LSI chip module, employing the microprocessor to realize water collection, processing,display reserving and storing the information of water consumption. With small dimensions, light weight, low power consumption,high power consumption, high accuracy,antijamming, high reliable, easy installation and maintence, long life battery, it is the best choice for realizing intelligent control by most of tap water administrative bureaus and property company, ideal for enhancing public awareness of saving water. Working conditions Temperature level:T30 Water pressure level:MAP10 Water meter pressure of Pipeline: 0.02 Mpa. Two ways to read card A: Common IC Card: LXSK-15(IC)~25( IC) B: RF IC Card: LXSK-15( SC) ~25(SC) Maximum permissible errors (1) in the lower zone from qmin inclusive up to but excluding q2 is ±5% (2) in the upper zone from q4inclusive up to and including q2 is ±2% Pressure lose: ≤1.0Mpa Pressure lose level:p 63.

FUNCTIONAL CHARACTERISTICS Close valve function: the meter will automatically close when it reach alarm level and shut off the water to remind the user to purchase water; at this situation, insert the user card, the valve will open. When the remaining amount to 0 T, the meter will automatically close the valve again to remind the user to purchase water. Low power hint fuction: When the battery is low, the valve gate will automatically close the valve and prompts the "E-07", cutting off water to remind the user to replace the battery. Antimagnetic attack function: the meter provides automatic protection function. When a magnetic field is close to the meter, the valve will automatically be closed. The card displays "E-03". Please check the surrounding environment whether there is the presence or absence of a strong magnetic field. After treatment, you can plug the user card to open the valve. MAIN TECHNILOGICAL INDEX
