WT Prepayment Water Meter

(Normal Temperature, IC Card,Horizontal)

The type WT prepayment water meter(IC Card) is a high-tech mechatronics integrated intelligent instrument composed of advanced microcomputer control technology as the core and intelligent card as the information transmission medium. It is suitable for automatic measurement and charging control of urban water supply, and the product meets the ISO4064 standard. This meter has accurate measurement, stable performance, and prepayment function, achieving the goal of paying first and then using water, completely solving the many contradictions that have long troubled users and water suppliers, and improving the modern management level of the water supply industry.

According to the category of IC cards, they can be divided into the following two types:

Contact type IC card water meter

Non contact RF card water meter

Specification:

◎ Prepaid function: Transmit water usage information through IC card in both directions, use water after charging, and automatically close without any charge.

◎ One card solution: This meter supports one card with multiple meters, and can achieve one card for water, electricity, gas, and heat meters.

◎ Display function: Users can visually view multiple information on the water meter, such as the current purchase water quantity, remaining water quantity, cumulative water consumption, switch valve status, low battery reminder, etc., with clear and intuitive display.

Low battery alarm function: When the battery is low or replaced, the water meter will automatically turn off.

Ultra low power LCD display function.

The unique battery compartment design adopts an external battery compartment structure, making it convenient for owners to replace batteries at any time. (This design has been granted a national patent)

Using a super large capacity high-power 3.6V lithium battery, the on-off valve is fast and powerful, avoiding the disadvantage of valve not closing tightly due to water rust and excessive water pressure.

Using imported ultra-low power chips, multiple encryption technology, and ultra-low power design, the static working current in the constant display state is less than 0.01 μ A. The battery has a service life of more than 6 years.

The exquisite appearance and clever design ensure that the control compartment is completely sealed. In addition, the circuit board adopts strict waterproof treatment, and the water meter is completely immersed in water for several days, ensuring that the water meter can work normally (for RF card smart water meters).

The stainless steel electric ball valve adopts German emulsification technology combined with bidirectional release design, which combines tightness and

Flexibility ensures reliable switching.

◎ Pollution and rust prevention function: The water meter regularly (every half month) opens and closes the valve to achieve automatic pollution discharge,

Avoid valve scaling, rusting, and other phenomena.

◎ Anti attack function: When the water meter is subjected to external strong magnetic electric attacks, the valve of the water meter will automatically close, and only

The valve can only be opened after external interference is eliminated, and the attack information will be automatically recorded.

◎ National limit function: When the recharge amount exceeds the limit, the water meter will not read the purchased water amount in the card until the sum of the remaining water amount in the water meter and the current purchased water amount is less than the limit.

◎ Pre alarm function: When the remaining water volume reaches the set alarm value, the water meter automatically closes the valve to remind users to purchase water in a timely manner. Users can continue to use it after swiping their card until the water volume reaches zero.

◎ Three protection functions: fully sealed design, truly achieving waterproof, leak proof, and anti attack.

Environmental level: Meet IP68 protection requirements (for RF card water meters).
