Technical Features
Structure and shape:
The product adopts modularized combined technique. The basic meter, Valve and the controller are independent parts which centesimally combined into the whole water meter. The structure is concerted and compact. Installation is easy and flexible.
Pulse transmitting meter
Improve the traditional structure of central part of machine; reduce the resistance of central part of machine; realize high preciseness, high sensibility and low flux.
Bear magnetism-off function when overflowed
Equipped with imported oboe for pulse transmitting; high sample security.
Valve and driver
Adopting self-designed low exhaustion anti-jamming machine; stable working condition and low exhaustion.
Adopt advanced valve, the pore of valve is set at the center of moveable valve, when the valve moves it will clean the pore of the valve, which give a guarantee of long working of the valve.
Controllable circuit
Hardware: adopt imported advanced multifunction zincograph
Software: human design, simple operation bearing functions of automatic judgment and adapting humid environment
Low exhaustion circuit
The product adopts functionally unique electricity-saving circuit design with highly-functional battery and lowly-exhausted instrument. The IC card water meter can be used for more than six years. The nuisance of changing battery is reduced.
Precise sample technique
The product adopts functionally unique pattern of pulse transmitting sample, which gives a guarantee of minimum error in statistics of water meter and controller.
System security
The product adopts dynamic coded arithmetic to realize one user, one card, one code and one user, one card, more meters, which guarantee the security of account of both sides of supplying water and consuming water.
Perfect sale software
The company develops multifunctional sale management software for system management, management business, statistics maintenance, statistics inquiry, blacklist management, statistics property on the base of design experience of finance.
Main Function
Sample meter:
The controller can automatically collect and store the metric statistics of water meter.
Purchasing function:
The intelligent water meter will automatically accumulate water quantity and show the remainder when users insert IC card.
Evincive/Valve-Shutting alarm
The product set alarm function of two degrees, that is showing alarm and valve-closing alarm.
Valve-shutting and water-stopping
Water meter will automatically close valve and stop watering when the purchased water is used up. It will recover when the user input new-purchased water quantity again.
Remainder inquiry
The screen of intelligent water meter will show the remained water quality as soon as users insert cards.
Information inquiry
Manager can inquire and information of water meter by using special "inquiry card".
Returning function
The remained water can be returned to users by using special "returning card".
Purchasing limited function
Water-purchasing limited prevent users from stocking up water.
Special measure
If the valve cannot be shutted off, users can continue to use water when purchased water has been used up. Modern instrument will automatically accumulate overused water quantity. When user input water quantity again, the instrument will automatically subtract overused water quantity.
Valve-shutting disturbed by magnetism
Water meter will automatically shut valve when disturbed by magnetism. It will not recover until"inquiry card" is inserted.
Battery self-protection
When the IC card is kept in the bayonet of water meter for a longtime, the water meter will automatically shut off electricity and stop showing to prevent battery from exhausting.
