This model of civil c-card prepayment charging intelligent instrument is based on the rotor type copper water meter, which is the most commonly used and most stable in the water medium measurement industry. It adopts the latest micro consumption function in the world, super large scale integrated computer chip module, reliable electronic controller designed and manufactured by means of highly integrated industry, equipped with ultra-low power consumption and large torque output voltage loss free motor control valve, etc The intelligent water meter is a high-quality product with the functions of prepayment, automatic billing, alarm and prevention of improper use.
Product use
It is used to measure, memorize and display the total volume of cold drinking water flowing through the tap water pipeline; it is suitable for small units and domestic water measurement.
Product characteristics
A. control the user's water consumption through the valve, so as to ensure that the user buys water before using water and the water selling unit receives the water fee in time.
B. high water resistance: wireless information transmission technology is adopted for data transmission medium to improve the water resistance of water meter.
C. alarm function: under voltage alarm of power supply and insufficient margin alarm.
D. hoarding quota function: it can effectively prevent users from hoarding water maliciously.
E. credit function: it has the credit function of zero water volume.
F. anomaly detection function: with strong magnetic field interference measurement signal or other abnormal conditions, the meter automatically records.
G. valve maintenance function: in order to avoid scaling caused by valve inaction for a long time and affecting normal opening and regular operation of the valve once.
H. bidirectional data transmission function: through the user's RF card, you can know the remaining water quantity of the water meter, whether the water meter is interfered, whether the battery is under voltage and other status information.
I. through the system software, the water supply unit can understand the user's water consumption, so as to make a scientific prediction for the production water volume.
J. through the system software, timely understand the usage and status of the water meter at the user end, so as to timely maintain the failed water meter.
K. through the system software, the step water price can be set and implemented for the water meter, and the effective management of water resources can be implemented to lay the foundation for the intelligent and integrated management of the community.
L. users can freely control their time of buying water, and can also clearly understand their own water conditions.
M. split structure, easy to install, user swipe card box can be installed in a reasonable location according to the needs, convenient for user swipe card.

Indication error limitThe accuracy level of this series of water meters is level 2. In the range of water temperature from 0.3 ° C to 30 ° C, the maximum allowable error of water meters is ± 2% in the high area (Q2 ≤ Q ≤ Q4) and ± 5% in the low area (Q1 ≤ Q < Q2). When the water temperature exceeds 30 ° C, the maximum allowable error of the water meter in the high zone is ± 3%.
