PREPAID SYSTEM INTRODUCTION
Overviews
IC card water meters are an innovative type of water meter that use electronically-readable IC cards to measure and track household water consumption.
Product features
·High Precision Water Measurement.
·Joint valve structure, suspension design, 1:3200 torque, Timed automatic cleaning. Ensure valve stability and smooth opening and closing.
·Long service life, 6 years battery life.
Advantage of the system
·OEM, language display and currency unit display can be customized, and company name can be added to the software.
·The data will be saved automatically after exiting the system.
·Simple management and user card making, easy to query consumption records.
Invoice printing, providing payment voucher to users in the most common form in the local area.
Brief introduction
The product consists of the bulk water meter, the butterfly valve and the controller. It is used for measuring the total volume of the water flowing through the pipe, with prepayment function available.

·communication:IC card reading/Private protocol
·Valve body with self-support type pilot-actuated structure, leading valve can be opened by smooth torsion, primary valve starts relying on the water pressure without the need for large power.
·Radio frequency card, high security, resistant to wear and magnetic
interference, waterproofing and anti decryption.up to domestic top-level.
·Dual indication feature of mechanical metering and electronic metering.
·Step charge function.
·Ultra low power consumption to extend the meter’s life span.
