- Q:Types of water meters
- According to the medium temperature can be divided into cold water meter and hot water meter, the water temperature 30 degrees is its dividing line(1) a cold water meter: a water meter with a lower medium temperature of 0 DEG C and an upper temperature of 30 DEG C.(2) a hot water meter: a water meter with a lower limit of medium temperature of 30 DEG C and an upper limit of 90 DEG C or 130 DEG C or 180 DEG C.
- Q:Household card water meter, the house valve is closed, no water, water meter is slow rotation, what is the reason?
- No, the problem still exists, now the problem is clearly not a problem with the meter is not check valve, water is your home stream, you do not find out where the water has gone, it is not assured, the most reliable method to call the tap water company, please pay their people leak. I'm sure I can find it. Charges vary from place to place. The table before the problem of tap water company, after the table is your own home, so you may need to pay for
- Q:How can the water level of the water meter be adjusted instantaneously?
- When the meter is repaired, it should be signed by the management to confirm the current readings. To the back, you have to turn off the water, remove the seal, remove the glass cover, and then pull out the pointer to the original reading, but if you secretly this involves stealing
- Q:Why does the water meter need the valve before and after?
- After the water meter, the valve is set for easy use.
- Q:On the trouble of household water meter
- You remove the clean up dirt in the water can be recovered, the premise is to find water seals, seals can find water meter or property, of course, mean to say, the meter will not affect the water storage and water meter, a water meter is probably not more than one hundred yuan the price is according to your water meter diameter set.
- 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:How to solve the water meter inversion?
- Because the anti reversing performance of the intelligent water meter is very good, the phenomenon of water meter reversal mainly appears in the ordinary water meter. First, the human factors in the reversing of the water meter, the manual bar, the reverse is man-made, and a few soil method is also very simple, as long as the water meter is removed, the installation can be reversed.
- Q:Does the new water meter go slower than the old one?
- First look at the table is what style, with some sideways, some never mind; as for the old water meter fast or slow, it is more complex, we still want to see what type of watch, you know, there are dozens of meter subdivision series, each series characteristics are not the same, and the influence of the length of time the different tables are not the same.
- Q:How to see the water meter, how to view the water meter?
- Digital water meter: more common in nearly five or six years of building or later replacement users,Similarly, the red pointer is the decimal portion, and the digits are from one to the left, ten, 100, thousand, and tens. This is easier. We can read the actual amount of water directly according to the figures shown above.
- Q:What should be paid attention to when installing water meter?
- Make sure the installation site is: water meter is installed in view, convenient, free from exposure, cold and non polluted,A water meter generally introduced into a pipe is mounted in a chamber, an external well, a well, a basement or a private room. Small water meter for household useOn the inlet manifold of each production. Water meter should be preceded by the valve, water meter shell from the wall may not be greater than 30mm, water center from anotherA wall (end) distance of 450 ~ 500mm, the installation height of 600~1200mm. To ensure the measurement accuracy of water metersIndeed, the upstream end of the screw wing type water meter shall have a linear pipe section of 8~10 times the nominal diameter of the water meter, and other types of water meters shall be front and rearA straight line section of not less than 300mm. When the length of the straight pipe before and after the water meter is larger than 300mm, it is applied beyond the pipe sectionHead led to the wall, along the wall laying, the center of the wall from 20 to 25mm.
