The RF card water meter (DN15) consists if a valve device, a movement, a sensor, a reducer, a battery, an electorinic module, and a radio frequency card. It has prepaid and cintrilled function.

It implements the CJ/T133 standard. The indication error and measurement width with the GB/T778.1 (equivalent to ISO4064).

The main technical parameters

Pulse constant: 10
Quiescent current: ≤6uA
Dynamic current: implements : ≤20mA
Actuator maximun current : ≤60mA
Working voltage: 2.8V to 3.6V
Q₁ to Q_2,excluding Q₂ indication error ≤±5%, Q₂ to Q₃ (including Q₂) indication error ≤±2%

Features

When the battery is not powered or the battery is replaced, the valve is automatically closed to effectively prevent water theft. When the battery is powered, the valve is automatically opened, which does not affect the user's water.
Anti-attack design, anti-magnetic, anti-vibration. When a magnetic object is close to the water meter, the valve is automatically closed to prevent the magnetic object from interfering with the meter.
Pre-paid function, after the card is recharged, the water is swiped, and the remaining amount or amount is automatically reduced when the water is used. The remaining amount is automatically closed.
For the query funtion, the user can query the remaining amount, water consumption and other related information on the water meter LCD.
One meter to one card, the user first puechases the water card and the water meter is bound, one water meter corresponds to one card is locked.
The card replenishment funtion, the replenishment card continues the data in the original meter and the amount or amount of water remaining
Anti fouling function, automatic opening and closing of the valve at regular intervals, not only prevent ball valve fouling, but also solve the lithium battery voltage hysteresis problem.
Power-down protection function, power off or no power, the microconteoller automatically saves data
Low voltage protection, when the battery voltage is lower than the set valve, the valve is automatically closed.

Q: What does "IP68" mean in the standard of intelligent water meters?: The second is the liquid protection level, in the range of 0-8, which represents protection from vertical water droplets to underwater pressure. The greater the number, the stronger the ability."IP68" is the highest level of protection for a water meter. Refers to the water meter can soak when long (electronic intelligent water meter for a long time to sink under the designated water pressure, can ensure that no damage caused by flooding).

Q: What are the technical specifications for the installation of water meters?: The installation location of water meter should be convenient for disassembly, assembly and meter reading, and the pollution of insolation and freezing should be avoided. At the same time, the water meter should be equipped with an oil valve to allow water to be removed and assembled and removed.

Q: The tap water, the water meter does not turn, what's the matter? The tap is all open: The water meter is powered by the flow of water inside the wheel rotation, drive and measurement of water consumption counting gear, if not turn or when the switch does not turn, there are two possibilities, one is the wheels are stuck and unable to promote the flow of foreign body, the rotation of the wheel, the other is not stuck, but not good occlusal gear drive. In short, the water meter is out of order.

Q: How long is the warranty period of the water meter?: Free replacement within 5 years, 5 years later by the water company check replacement

Q: How does water meter read m3? What does it mean?: Direct reading water meter reading: direct reading water meter can be read directly from left to right according to the black indicator, the measurement unit is cubic meters (ton), and the red indicator number can not be read

Q: How long can the smart water meter battery work?: Smart water meters in daily use, power consumption in the following areas:Battery self discharge, valve switch power consumption, credit card communication power consumption, liquid crystal display, power consumption and so on.

Q: What are the functions and characteristics of intelligent water meters?: Security: a table (or a household) a card, automatically generate and identify IC card password.

Q: It is normal to add a valve before the water meter: Normal water meters will not be installed before the valve, that is tantamount to help others steal water in disguise

Q: How to solve the water meter inversion?: Because the anti reversing performance of the intelligent water meter is very good, the phenomenon of water meter reversal mainly appears in the ordinary water meter. First, the human factors in the reversing of the water meter, the manual bar, the reverse is man-made, and a few soil method is also very simple, as long as the water meter is removed, the installation can be reversed.

Q: What if the intelligent water meter is not accurate?: The intelligent water meter is a new type of water meter which uses modern microelectronic technology, modern sensing technology and intelligent IC card technology to measure water consumption and transfer data and settle transactions. When the water meter is abnormal, the background can be monitored in time, and no one can be stopped.
