LXSP IC Card Prepaid Water Meter
The IC Card Smart Cold Water Saving Meter is a mechatronics smart meter which is formed by the microcomputer controlling technology as its core and the smart card as its information-medium, it is equipped with double measuring function of mechanical as well as electronics counting. It is main made up with IC card reader, low power consumption micro-computer, original new motor valve, flow collector and corresponding circuit. It also equipped with the electronic display while maintaining the characteristics of the traditional mechanical water meter.
Technical standard: CJ/T133-2001 and GB/T778.1-1996
Application:
--Measuring the volume of cold (hot) water passing through the pipeline.
Features:
-Under small flow rate (including drip) measured at the channels of the new monarch, initiating the flow is less than 2 L/H, drop of water metering;
-Effectively prevent the improper water consume action of drip method and prompt the user repair the leakage phenomenon of the pipeline as soon as possible, and enhance the water saving consciousness of users;
-Take IC card as information carrier, have extremely strong confidentiality and anti-jamming;
-Taking the working mode of one card matches multi meters, means the user hold a card, which is able to manage several meters from the same user, it is economy;
LCD display: Water volume, valve status and various working conditions of the water meter, Intuitive and easy to understand;
-Low voltage self-testing: the valve shall be shut down and "under voltage" shall be displayed once the battery voltage is lower than the setting threshold, restart after the battery is replaced.
-Water shortage tip: the valve shall be shut down automatically once the rest water less than the the quantity valve alarm value, inform the user to buy water, the valve opened after insert effect card, can be continue to used until the rest water to the value of 0, then valve closed.
-Special function CARDS: convenient for maintenance;
-Mechanical word wheel display remained: Double display mode with mechanical and electrical.
-Ultra low power design, battery lifespan more than 6 years.
Working condition:
Water temperature: 0.1ºC~40ºC
Water pressure: ≤1Mpa (1.6MPa for special requirement)
