Intelligent water meter/IC card water meter Battery

IC Card Water meter/intelligent water meter is an intelligent water meter products, at this stage has begun to promote the application of many pilots, because it is necessary to install the battery, to work, display data, so some users have produced such questions: if the IC card water meter/intelligent water meters is power off, will the water supply be cut off?

Multi Jet Water Meter     Prepaid water meter  

intelligent water meters need to recharge to buy a drink to use, after buying water on the meter inserted IC card, to water. However, in the use of the process, because of forgetting to replace the battery, many users found that the insertion of IC card, LCD screen has not shown the number, at this time will occur two kinds of possible problems, one is inserted card, water meter does not show the number, but the supply of normal tap. There will also be a situation, that is, immediately water. What are the reasons for these two different situations? This is because the IC card water meter/intelligent water meter motherboard battery and panel battery is different, if the LCD is not displayed, and will not affect the user normal water, at this time the user should replace the battery as soon as possible. And if the real water supply in the home, then there is almost only one reason, that is, intelligent meter monitoring to run out, automatic to the brake plate issued a signal.

Analysis of the advantage and application of remote water meter and technology

1, the advantages of remote water meter Because it appears the basic goal is to solve the immediate acquisition, water meter measurement, supervision and other issues and, therefore, it has obvious advantages in these areas. Because the water is collected, so the way to have a strong deterrent effect, so that users can’t easily plays on the water meter, which makes it stolen water is greatly reduced. Comparison analysis on the water, you can fully understand the volume and abnormal water, to predictive decisions. In addition, the meter from the original manual, data processing can be done directly through the system. 2, remote water meter application

Because remote water use for a short time, and no mature technologies and successful experiences to learn from, plus in the early days of mostly water meter pool, easy because the table pool water and management problems, often leading to remote data base table data and bias issues. The past few years a household one remote system operation analysis, at present mainly has the following problems: ① remote transmission system deficiencies, such as remote acquisition system failures, sensors fault and some induction magnet demagnetization. II water supply quality problems, such as facilities, pools of stagnant water leaks, water meters, some sensor is failure by soaking water, oxidation, affecting the transmission accuracy. ③ external power supply cause problems, such as power failure causing data errors. ④ human factors issues, such as collector was stolen, sensor line transmission system data loss caused by vandalism, signal line, base set wrong or upside down, private tables, tables, and so on. 3, technical analysis of telemeter system Remote Reading Water Meter

(1) far biography meter main has pulse type and straight read type, currently in domestic widely using of far copying table system main for pulse (dry spring tube sensing) way, but due to its itself of design problem, exists following shortcomings: a is its has itself power of features, external for received power brings of inconvenience and fault; II is touch points fibrillation more count and induction not sensitive less count; three is magnetic weakened lost data; four is foreign magnetic field of interference; five is pulse way must online run, not continuous work, Event of a power failure or communication line failure, will cause a permanent loss of pulse number; six are uncorrectable in pulse mode, seven are system needs to set up initial values before running, needs manual meter reading one by one, the high volume. (2) in recent years, have developed point to point on the international emission direct-reading remote water, domestic research department are also developing applications. The products and pulse (dry spring tube sensing) way has unparalleled of advantages, first, for external blackout not effect meter count; second, regardless of what time read table, read out of data are and meter dial Shang of shows value data consistent; its three, in General meter embedded loaded data acquisition and remote communications module, improve has table with and system of reliability, and stability and using life; its four is, data acquisition convenient, can will the measurement value by corresponding communications interface directly transmission to copy table Management Center. From the perspective of practical effects, direct-reading water meter accuracy is much higher than any other way. In addition, information received from other cities at home and abroad: using direct-reading remote water meter accuracy of results obtained by ideal, is becoming a household one preferred way of remote.
