- Q: How much water can be overdrawn by a cassette meter?
- The card marked (a chip), the first to open the cover of the water meter, a water meter card socket, a plug on the LCD digital display, digital Arabia, the remaining tonnage, if the water meter installed in the cabinet, see, with a lighter lighting, while to the left I 5T get a card inserted automatically without water, there is water, is equal to the tips. To buy water, then up to 50T, even the table of the word, that is 55T.
- Q: Water meter display, replace the battery after water, why not start after the card water meter?.
- Card insertion method: in front of the user's card holder, insert the guide slot in the direction of the arrow, observe the LCD screen, and make sure the LCD screen is correct before you can pull out the card. Note: when the card is not finished, it is forbidden to draw the IC card, otherwise it may damage the IC card, and the data in the IC card may not be stored in the water meter, and it may cause the loss of the purchasing water in the IC card. If the card is wrong, try the card again. Make sure the card is inserted and not inserted.
- Q: Must the new water meter be checked before use? Does the state expressly provide for it? In which regulation do you specify clearly?
- Water meters belong to measuring instruments, and should be adjusted by the People's Republic of China metrology law.
- Q: How high is the installation height of the water meter box?
- If using vertical type, the location of water meter must be determined in advance, the foundation of the cement is built, and the horizontal size of the foundation is 800CM*350CMHighly regarded, ground soil depends, is generally 50CM, where 8CM is the cement pouring surface (expansion screw, the underground part of 40CM, on the part of 10CM, stent size meter box is 750*250*30, material for the 201 moment steel 25*40*0.8
- Q: How do you check the water meter?
- Calibration and inspection, the general water meter is running more slowly, open the movement, adjust it
- Q: Water meter rotation, turn off the valve will not turn, but did not find leakage
- The accuracy of the former is higher than that of the latter, but it requires high water quality and is easily blocked when the water contains impurities. An instrument for recording the amount of water used in running water is mounted on a water pipe, and when the user leaves the water, the pointer or wheel turns on the table to indicate the amount of water passed.
- Q: Is there a national standard for the metering accuracy of tap water meters?
- The new national standard "closed water meter water flow in full pipeline measurement of drinking cold water and hot water meter gb/t 778 - 1 - 2 - 3 - 2007", instead of the original water meter national standard "cold water meter gb/t 778 - 1 - 2 - 3 - 1996" [1], launched in May 1, 2008. Compared with the new national standard, the original national standard changed greatly, and there were nine aspects of change, including the re establishment of the flow parameters and their relations of water meters". The change in this aspect will directly affect the metering requirements (measurement characteristics, maximum allowable errors) and technical requirements (material and structure, durability, calibration device) of water meters. Therefore, the reasonable selection of the flow parameters of the water meter is an important basis for the measurement, technology, test and verification of the water meter. It is also an important sign of the quality level of the water meter.
- Q: Water pressure is too large, water meter will be deviation?
- Water pressure will affect the water meter, you should belong to the water meter rotation pressure fluctuations in the problem, that is, affected by water pressure
- Q: Why should the water meter be horizontally installed?
- If your water meter is horizontal (the water meter reads the disc with a H), be sure to level it. However, you must pay attention to your water meter installation position, must facilitate the look-up table look-up table is tilt meter industry installation not large, inclination has little effect on the flow is large, but the flow of small will be too large
- Q: Water meter no reason to turn around, how to solve?
- Many reasons for water rotation, but on the whole can be divided into two: one is the subjective factors, namely subjective causes, such as construction acceptance, human responsibility caused by Water Leakage, original gas gathering, which can strengthen the construction management, improve the staff's work and to improve the level of responsibility. The two is the objective factors, the main characteristics of the water itself, by the characteristics of pipeline and the level of technology development in the external objective factors, on the one hand to work in the future continue to explore the improvement will be improved.
