Card type smart water meter has functions such as advance water charge, balance reminder, step water price and waterless shut-off valve, etc., which can meet all the requirements of conventional installation environment, economical and cost-effective. After five years of market research, Shunshui ordinary card-type smart water meters have been unanimously recognized by new and old users in terms of function, price and stability.
Product features of card smart water meter:
1. Date and time function: Date and time are recorded in the water meter.
2. Battery voltage detection function: close the valve when the pressure is low, and the card can open the valve; close the valve when the voltage is low, and do not accept stored-value cards.
3. Anomaly detection function: When the water meter encounters external strong magnetic interference to affect the normal operation of the water meter, the water meter valve is closed; after the magnetic interference is eliminated, the valve can be opened with a stored value card.
4. Liquid crystal display function: The liquid crystal of the water meter can display the remaining amount, the current consumption amount, the cumulative water consumption, the program version number, the water meter number, the current unit price, the date and time and other related information.
Technical specifications of card smart water meter products:
Various technical indicators and testing standards meet the requirements of CJ / T133-2007 industry standards.
The cold water base meter conforms to the national standard GB / T778-2007, and the hot water base meter conforms to the JB / T8802-1998 industry standard. The length of the IC card water meter and the size of the screw connection at both ends are the same as those of the conventional water meter, which can be replaced directly during installation.
Measurement level: level 2;
Working pressure: ≥1.0MPa;
Pressure loss: ≤0.1MPa.
Controller working current: open and close valve current> 100mA;
Quiescent working current: <5μA.
Working voltage: 3.0-3.6V.
Measurement method: double pulse sampling method.
Valve durability: The valve is opened and closed ≥1000 times, and the leakage is ≤0.015m3 / h.
Power supply and service life: 3.0 V or 3.6V lithium battery, 1 life, service life> 6 years.
Pre-payment: It can realize the pre-charge function, that is, the IC card is used to recharge and sell water, and the card automatically closes the valve at no cost.
Balance reminder: According to the actual situation, you can set the prompt water amount, and prompt the top up when the balance is insufficient.
Waterless closing valve: When the balance in the IC card is "zero", the water meter automatically closes the valve and stops the water supply.
Data retention: The data are memorized by themselves, and the retention time is ≥10 years.
Conditions of use: indoor installation, no direct sunlight in the surrounding environment, no harmful gas, no strong electromagnetic field interference, cold water meter: medium temperature range: 0.1 ℃ -30 ℃; ambient relative humidity not exceeding 93%; hot water meter: medium temperature range : 30 ℃ -90 ℃; the relative humidity of the environment does not exceed 93%; water quality: in line with national standards for tap water.
