Prospects prepaid meter and analyze the merits of state

Pre-paid water meters in use often have problems following cases can be drawn through the merits of pre-paid water meter test:
1, abnormal shutdown: In the case of non-exhaustion of water, water shut-off valve, causing the user inconvenience. For example, high-rise towers, if high-frequency supply pressurized water resonance, very likely to cause the valve shut-off, which is mainly manifested in certain valve solenoid valve and poor quality water meters.

2, electromagnetic interference: a magnet close to the water, which will make the output signal can not be pre-paid water meters, resulting in not charging less billing, if the meter shut off valve, indicating anti-electromagnetic interference function, but how to deal with EMI after valve reopen issue, but also the performance merits of the standard meter.
3, Battery life: Many manufacturers nominal built-in lithium life of more than 6 years, less than two years of actual use, more months that is draining the battery manufacturers, is to use a large part of the water meter valve, when there is water inside impurities on the valve open or closed position, and intelligent software design does not have to determine the function, resulting in continuously driving the valve of batteries exhausted. Must identify whether the electricity meter detection alarm function, and how to deal with, if lack of electricity without any treatment, resulting in exhaustion of the amount of electric power and the battery is not enough to close the valve, will allow users of water in vain, water companies and property management sector losses, if Close the valve in advance, letting users is very inconvenient, which is the evaluation criteria.

Water shortage is China’s basic national conditions, lack of water to China’s economic development and social life of a huge negative impact. Shortage of water resources to promote the reform of the smart meter industry, these price reforms effectively improve citizens’ awareness of water conservation. Beijing prepaid meter price ladder is to achieve the most realistic option.
Analysis of pre-paid water meter advantages:
(1) can be overcome without electricity live situation as usual.
(2) life of up to six years, lithium batteries can be replaced.
(3) significantly reduce communication costs, the monthly minimum is $ 5.
To sum up: Many companies consider Beijing smart meter site without electricity in the actual situation, recommend the use of lithium battery-powered mode, both overcome scene harsh environments, battery life is also more than 2 years, while communications costs are low , but also to meet the water requirements of the Division for the amount of data. Of course, there is the case in the field of electricity can also be used for AC power supply, all in all, two power supply mode can be selected according to the actual situation.

Advantages and disadvantages of a variety of prepaid water meter

1, code prepaid water meter:
Advantage: card is not required for data exchange. So there is no lost cards, buy water don’t need a card.
Disadvantages: if function, the code will be very long, is very inconvenient to use. Feature was too simple to realize only basic charge. Water meter installation requirements, user if you do not see clear water meter can’t recharge it. Some elderly people are not able to use.
2, TM card water meter:

TM card can be thought of as a two-wire IC card, card reader site leakage, very easy to be destroyed. For button-style packaging, storage is not very convenient. Cost and IC card water meter and flat. Neither have the price advantage, and has no quality advantage.
3, wired remote prepaid water meter, also known as valve-controlled tables:
Advantages: real-time monitoring meter running, and fully functional.
Disadvantages: as the wired remote water meter, and prices for water meter is used connected to a host. Routing is complex. Very easy to be destroyed. For example users to cut or short circuit. When there was no where to be destroyed. Running user’s maintenance charges are high. Than to the mass promotion conditions.
4, wireless remote water meter:
Advantages: can monitor in real time the meter running, and fully functional, easy to install. A model is the next best.
Disadvantages: costs about one-third above the IC card water meter. And the technology is still immature, anti-jamming ability, running unstable, does not currently have the mass promotion conditions.
5, IC card intelligent water meter:

Advantages: low cost storing large amount of data, fully functional, is now the market is the most widely used products.
Disadvantages: slot, part of the card is therefore prone to rust or gets dirt in the cause of reading failure.
6, RF card water meter:-T5557 RF card and M1 radio frequency card
The T5557 RF card water meter
Advantages: radio frequency table because there is no card slot, moisture-proof waterproof, card reader and long service life.
Disadvantages: the manufacturers in order to reduce costs on the market today are the T5557. Functional and simple. Recharge can achieve. Cannot write-back user consumption. Water supply companies can not do analysis of profit and loss.
RF card water meter M1:
Advantages: no slot, moisture-proof waterproof, card reader and long service life. Data storage capacity. Users each month of water usage, user usage write-back to the system. This type of card in the bus system, campus one-card system, the city card system to be widely used, card technology is very mature.
Drawback: since than conventional IC card water meter and the T5557 card water meter costs about 20 Yuan, so even though the card is ideal for utility charges system, but there is no water supply enterprise support for areas of hard water charges to get mass promotion.
Smart prepaid water meter can be divided into:-IC card water meter, water meter, RF card code prepaid water meter, TM card water meter and wireless remote water meter wired remote prepaid water meter.
