Q:How to deal with leakage of water meter?
To see whether it is the tap water meter Water Leakage trading settlement meter, if it is, then you can call the local water supply service hotline, the replacement is free, if not installed the tap water company trade settlement meter, then contact the property or to replace the line
Q:Who will be responsible for the leakage of water before the water meter?
In accordance with the relevant provisions of the commercial housing pipeline warranty period of 2 years, in the warranty period, the construction enterprises responsible for maintenance, such as the formation of economic claims, but also by the construction enterprises.
Q:Which kind of water meter is more convenient for large-scale projects? The best engineering case can refer to
And intelligent water meter is also divided into two series, one is prepaid type (pay first after water), and the other is data remote type (remote meter reading). The problems solved by IC card water meter and remote transmitting water meter are different.
Q:Why did the water meter suddenly stop IC?
The phenomenon of money off valve is the remaining money in the card list, less than the warning valve, but the card table valve automatically closes. There are many reasons for this phenomenon. First of all, it is necessary to exclude whether due to pipeline reasons, such as jitter or strong magnetic attack table, resulting in automatic shutdown of the meter. There is also a card board of your house, the chip is damaged by damp, need to replace a circuit board module, I have been a water meter for many years, you have seen such a lot of examples
Q:Do you know the working principle of dry water meters?
The water meter is divided into a wet type water meter, a dry type water meter and a liquid sealed water meter according to whether the counter is immersed in water.
Q:My water meter in the absence of water, water meters on their own table?
pressure fluctuationSince water is a liquid, the physical properties shown in general are incompressible, but in the water pipe the pressure of the pipeline is higher, and the water will show a certain compressibility. In the tap water pipe, the pressure fluctuation is inevitable, and now we are using the water meter is a mechanical watch, in which water flow generated by the kinetic energy to drive gear, so as to achieve the purpose of water metering. When no water, the water pipe ends are connected in a certain amount of high pressure water are fixed; therefore, when the municipal pipe network pressure rises, the volume of tap water pipe after the table shrinks due to the increase of the pressure, this will have a trace of the water through the water meter, is generated; when the pressure is decreased, the table after the tube in the compressed water with low pressure and expansion, will also have a trace of the water through the water, the difference is this time reversal. As we all know, the general mechanical table in the water is in the drive gear, is turned upside down when the water is in progress under the drive gear reversal, the drag force of water phase is different, although the two head of the same amount of water, but reflected in the reading on the meter is very different. According to statistics, in the absence of air in the pipeline, the resulting water is very small, about 0.5-1m3/ months. Under normal circumstances, the water users will not pay attention to; at the same time, this is also the normal level of measurement results.
Q:My water meter dial has a big bubble, bubbles move, flower needle on the turn (no water in the home), there are bubbles that normal, there are said to belong to the water meter is defective
The bubble is normal does not affect the use of dynamic pressure meter bubble that loss of pressure loss flower needle rotation but not fast that your neighbor has water you look at the bubble sometimes sometimes small bubble big your water pressure
Q:My water meter is upside down. What's the matter?
If it is from the date of installation, this is the problem of the water meter itself and the possible internal structure problems.
Q:How can I distinguish water meters from dry ones?. Still wet?.
Gear box of dry water meterThe counting mechanism of the dry water meter depends on the gear box to be separated from the tested water, so the bottom and the circumference of the gear box must be able to bear the force 2MPa pressure test without deformation. For this reason, in designing dry water meters, more than ten reinforcing ribs are added to the upper and lower parts of the gear box, and the metal bowl lining is often lined on the bottom and inner walls of the gear box to prevent its compression deformation. The center of the upper and lower parts of the gear box is respectively provided with an axle hole, which is respectively matched with the central gear shaft and the impeller shaft. In order to reduce the friction of moving parts, improve the starting flow value, generally has a concave surface on the bottom shaft hole (or plane) jewel bearing. The counting mechanism of dry water meter, in addition to the gear box around and bottom of the water will be separated from it, it is best to gear box top also take good sealing measures, in order to prevent the outside of the sewage flow invasion count mechanism.
Q:How high is the installation height of the water meter box?
If the wall, water meter placement must be determined in advance, the vertical direction at the bottom of the ground distance of not less than 25CM, and in the horizontal direction in the box after the reserved 28CM to install the table after the tube, if the ground sand cement structure, is needed to break the cement pavement for pipeline installation.
