Why prepaid smart water meters have become the mainstream of the water meter industry

<>1. The biggest feature of the prepaid smart water meter is its prepaid function, the user has to pay the fee before using the water, which realizes the commodity attribute of water, and facilitates the rapid return and centralized management of the funds of water supply enterprises, so it is favored by the water supply department.

2. The prepaid smart water meter does not need to be manually read to avoid many inconveniences caused by manual meter reading to users, and the historical water purchase data can be saved for easy user query.

3. The prepaid smart water meter can purchase water and water according to the user's own needs, and will not incur late fees due to arrears and increase unnecessary expenses. At the same time, it can well solve the charging problems of scattered residential users, temporary water users, and users who are often in arrears.

IC card prepaid water meter has always been loved by the majority of water resources management departments with its unique advantages and high cost performance. The IC card water meter solves the problem of the management department in terms of meter reading and charging in terms of user water.

"Pay first and then use water" is the biggest highlight of the IC card water meter, only the tap water user in the card first in the water bill recharge, can be used to swipe the card water, saving the management department a lot of manpower to read the meter, and also basically solve the problem of difficult charging.

At present, there are many types of IC card prepaid water meters with different configurations on the market, and there are also all kinds, so you must keep your eyes open and identify the quality of the product when purchasing, because this determines the service life of the water meter.

Summary. Since the stored value card is prepaid and does not require meter reading, the monthly water consumption and pipe network leakage data of the water supply company cannot be counted and assessed; The cost is high, and the cost of periodic verification, maintenance and replacement is high.

As the name suggests, the smart water meter can be read without meter reading, and the following are the advantages that I have sorted out for you: the cost is lower, the amount of data stored is large, and the members of the group can be perfected, and it is now a widely used product in the market. Cons:

There is a card with a mouth, so it is easy to rust or enter the dirty part of the card to cause the card reading to fail.

Since the stored value card is prepaid, there is no need to read the meter for shortages, and there is no evidence for the monthly water consumption of the water supply company, the leakage of the pipe network, etc., which cannot be counted and assessed; The cost is high, and the cost of periodic verification, maintenance and replacement is high.

This can be preset through the meter reading system, which can be the remaining amount of water or the remaining water fee, and the specific amount can be preset in advance.

Water meter, is to measure the flow of water instrument, most of the water cumulative flow measurement, generally divided into volumetric water meter and speed water meter two categories, originated in the United Kingdom, the development of water meter has a history of nearly two hundred years, when choosing the size of the water meter, should first estimate the size of the flow and the flow range used under normal circumstances, and then choose the commonly used flow closest to the value of the size of the water meter as the first choice.

The internal structure of a traditional water meter can be divided into three parts: shell, sleeve and inner core from the outside to the inside. The shell is made of pig iron, and the water exits the water inlet through the lower part of the shell, which is called the "lower ring chamber". At the top of this annular space, there is an "upper ring room" that communicates with the water outlet.

At the bottom of the sleeve there is a filter with small holes to filter out debris in the water. There are two rows of round holes on the side of the sleeve, and the position of the holes is exactly opposite the upper and lower ring chambers of the shell.

Of particular note is that both rows of holes are punched diagonally in the tangent direction of the circle. Note that the top shirt destroys the two rows of holes in opposite directions. Water flows in the tangential direction from the lower discharge hole, which is bound to form a rotating water flow, which is very important for the work of the water meter.

The inner core is divided into three layers: upper, middle and lower, and the upper layer is visible from the glass window, with only the pointer and dial. In fact, the most important thing is the lower layer, which has a plastic wheel with many plastic blades on the side of the wheel, called "impeller".

Generally, the more common prepaid water meter is the IC card prepaid water meter, which is a new type of water meter that uses modern microelectronic technology, modern sensing technology and intelligent IC card technology to measure water consumption and carry out water data transmission and settlement transactions.

The prepaid water meter adopts the mode of paying first and then using water, which does not require manual meter reading, and also solves the problem of difficult charging. The user should take the IC card to the water supply department for recharge, and then the recharged IC card will be close to the prepaid water meter swiping area and the IC card information will be entered into the water meter, the water meter will automatically open the valve for normal water supply, and the water fee will decrease with the increase of water consumption, when the remaining water fee is lower than the set value, the water meter will close the valve to prompt the user to buy water, and when the user swipes the card again, the water meter will open the valve to supply water, until the water fee is zero, close the valve again to stop the water supply, at this time the user should take the IC card to recharge and brush it again to supply water normally.

Pay the money first and use the water later.

The user will hand over the water bill to the management department, the management department will write the purchased water into the IC card, after the user enters the information in the IC card into the water meter, the water meter will automatically open the valve for water supply, in the process of user water, the microcomputer in the water meter will automatically reduce the remaining amount, after the purchased water is exhausted, the water meter will automatically close the valve and cut off the water, and the user needs to re-purchase the water after swiping the card to open the valve for water supply.

Prepaid: Pay first, spend later. Like an IC card, a bus card.

It is to buy a certain amount of water with the card first, insert it into the water meter, and then use the water, and when there is no money, the meter will automatically close the gate and run out of water.

There are a variety of charging methods for smart water meters, such as: 1. Charging according to consumption: Calculate the water fee according to the amount of water consumed, and the cleaning and elimination is generally charged according to the ** per ton of water.

2. Fixed charge: Generally, according to the capacity of the water meter, the water fee is charged according to a certain amount, such as a fixed monthly charge of xx yuan. 3. Tiered charges:

According to the different stages of water consumption, the answer is changed to know the different **, generally the more water consumption, the higher the water consumption, the lower the water consumption.
