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 Q2, 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: How can one way water meter be controlled by one way?
- A one-way control device is installed at the water inlet end of the rotor wet water meter, the inner surface of the device is composed of a water inlet end and the water meter shell with a threaded connection with through hole plug, T valve spool and valve plug in and plug, and set the reset spring valve rod in T valve spool on the form. The spool rod in a movable fit way through the center hole plug in T shape at the top of the valve core is a round table, using the reverse flow of top pressure, so that the cone cone and cone shell inlet end face seal, cut off the water, to achieve one-way control.
- Q: Why does the water meter need the valve before and after?
- If the meter is broken, or tap water companies who want to change the water meter, before and after valve are closed to open water will not have water leak out, otherwise the pipe flow out not get home in a complete mess.
- Q: My water meter dial has a big bubble, bubbles move, flower needle on the turn (no water in the home), there are bubbles that normal, there are said to belong to the water meter is defective
- Now has changed two, but also like that, but next to a few tables are no blisters, I have, and can not think of it, ask for advice, thank you!
- Q: The difference between rotary vane water meter and screw wing water meter
- Rotor type water meter rotor type water meter is suitable for small diameter pipeline unidirectional flow measurement. Such as total household water metering caliber 15mm, 20mm specifications of pipe. The water meter is mainly composed of a casing, impeller measuring mechanism and a retarding mechanism, as well as indicator, has the advantages of simple structure characteristics.
- Q: After the new house enters the family, has not discovered the water meter and the electric meter, where, in the house also does not have, where can find
- Secondly, through the above or not found, you call the property directly under the Advisory, you can, the new residential property is still very responsible person.
- Q: What's the tool for changing water glass?
- Then independent meter for the glass cover, you can not get any professional tools, only a small hammer. Find the water above the golden copper lid four lobes (ear) the most stout, gently tapping with a hammer, with patience, action to light, otherwise it will knock on the fracture may of course angle, the rest of the three corners of the best turn out of a few, a full range of shock and loose best. Light knock on a corner of the copper will break the weak. It is an important direction, counterclockwise or clockwise, one that is not good, and generally seems to be with words (such as 15MM) arrow in the opposite direction, tapping (must be light, slowly) a few will be released, not to knock on the side, is a hammer knock, and as close to convex the root of knock, with a round wall slide better, so as to better reduce the salient sections of excessive force to fracture problems. Of course, if you can't hit it, change it in a different direction. Only about two directions should be used flexibly. The above operations must pay attention to the integrity of the above copper cover ears, even if only one of the four knock off, the tightening force is much lower, will definitely affect the tightness, the basic copper cover will be scrapped.
- Q: Please tell me the accuracy level of the water meter
- Accuracy level and measurement level of water meterThe accuracy level and measurement level of water meter are two different concepts. The accuracy grade provides the indication error limit of water meter, and the 2 stage indicates the maximum indication value of water meter, and the error can not exceed 2%. The new procedure has 1 meter water meters, but it must be marked on the water meter.
- Q: How to modify the water meter?
- Please specify the master meter maintenance, change the numbers after re installed the new seal seal clamp. They can do it without being noticed. But it is against the law to do so.
- Q: IC card intelligent water meter battery? Just plug in card payment did not respond
- As a matter of fact, there are many reasons why the intelligent water meter does not produce water. It does not mean that the water meter must be out of order. In the face of water intelligent water meter, excluding the impact of external factors such as water, should be timely check the remaining water into the user card, when everything is normal and water balance is adequate, part of LCD display the remaining water and the "valve" signs; when the display is "valve off", "alarm", that the remaining water is insufficient, the user the user must hold the card to buy water buy water, complete recharge card to open the valve, water meter to water again.
- Q: What should be paid attention to when installing water meter?
- Connection mode: DN = 40, with screw connection; when DN is greater than 50, with flange connection.
