Item	Functions
Display	LCD screen	Display status of input water volume, surplus water volume, total volume, payment, closed, open, error, low battery, under attack
	Digital show	maximum total water volume9999.9m3
	Water supply control	Auto closes the valve when water volume is little, and open when inserting new prepaid card.
Auto control	Low battery alarm	Auto closes the valve when battery is low, prompt to change the battery.
	Hardware security	Auto closes the valve when the pulse line is cut off, and alarm under attack, which must repaired by administrator.
	Anti magnetic attack	Auto closes the valve when strong magnetic close to the meter, need inserting card to reopen the meter.
	Power off detection	Detecting the circuit after power up to check normal or not.
	Waterproof	Reading card as normal even the meter part is in water.
	Auto maintenance	Automatic switch valve for discharge once a month.
	Water quota	You can set a limit to use water. Unable to input water volume more than limit.
	Zero-crossing solution	User information would feedback to the superior software for processing when the valve failure to close in zero-crossing. Extra water volume will be record.
Working features	Moisture-proof pulse line	The pulse output is not affected by moisture, data will record as normal.
	Multi-application card	The first inserting of card in a new water meter will write in Card No. User ID, Water Volume. A card would serve in a total of 4 set of cold water meter, hot water meter, heat meter and pure-water meter at the same time.
	Data Recovery	When the meter is damaged, please insert the read-in card to collect user data and transfer data by inserting to a new meter.
	Initialization	Remove all information in the meter by inserting Initialization card, and set the starting line of water meter.
	Control card	When the meter break down, please insert control card to detect fault or to force the valve open.
	Card Reissue	You can register a new card with original data if lost the user card.
