 Product execution standards: GB/T 778.1-2007“Measurement of water flow in fully charged closed conduits- Meters for cold water and hot water",

                     CJ/T133-2012"IC card cold water meter".

Features:

 Ladder water fee: using single chip to charge in real time, the ladders are set to be three

 Magnetic protection function: water meter will shut down automatically when meets exterior strong magnet attack, and the user can open the valve by swiping IC card.
