- Q: How to see the water meter, how to view the water meter?
- Pointer type water meter: this kind of water meter is more common in a bungalow or an old building,The red pointer part is the decimal part, when the pointer from the extreme position clockwise direction up to a digit, you can read the use of tonnage. And so on, followed by a black pointer, ten, hundreds and thousands, read text as we watch the same readings can be. In the example above, we see a number of pointers between 5-6, ten bit pointers between 0-1, and 100, 000 pointer 0, then the table is 5 tons of water, because of its very is 7, so less than 6 tons of water, 5 tons of water is half the 10 tons of water. So, the ten pointer between 0-1, 100, 000 far, not in hand.Monthly water use, that is, this reading reduces the difference between readings.
- Q: The total water meter and the total value of the water table vary greatly
- This is normal, the sensitivity of the water meter is not the same, the same flow, the high sensitivity of the water meter will turn, and the low sensitivity of the water meter will not respond. There may be leaks in the pipe, especially where the pipes are joined.
- Q: Has the number of water meters been accumulating? Should the water use of this month be reduced by last month? Will it be cleared?
- Will not be cleared, for example, in January the water meter readings 1120, February degree 1150, then this month the amount is 1150-1120=30 (ton)And the degree of each month will be recorded, do not be afraid of mistake, and now the management is very scientific and technological
- Q: Just renovated house, no water, water meters will turn? What's the reason?
- The water pipes are empty, the air will "take advantage of a weak point; when the recovery water, the water pipe of the air pressure to the indoor pipeline all the blind end, the formation of" compressed air ", until the air pressure and water pressure balance so far. There is an interface between gas and water, when the pressure difference between the two sides of the interface is zero; and when the water pressure changes, the two sides of the interface form a certain pressure difference, and the gas and water balance is destroyed. To compensate for this pressure difference, to reach a new equilibrium, must change the pressure of the air, causing air volume expansion or contraction, thereby causing the pipeline "connector" in tap water flow, so the "idling" phenomenon is produced.
- Q: What about rust on water meters?
- I don't quite understand. Is it rusty? If the use of time is too long, rusty, it is recommended to change a new table. Old table may have been inaccurate, and then do wrong rust, rust, paint processing meaning is not large, but also to spend money, a new table also dozens of dollars. I hope I can help you
- Q: Plug in the water heater. What's the reason for the rotation of the water meter?
- If the water meter will usually autobiography, indicating that your home water pressure is not stable.
- Q: Where is the backflow preventer installed?
- Drainage facilities shall be installed in the installation area.Valve should be installed before the valve (butterfly valve) filter and rubber soft joint (or telescopic device), valve installed after the gate valve (butterfly valve).
- Q: Why can the high level intelligent water meter be equipped with a check valve that can not prevent the water meter from idling?
- The air sac causes a greater amount of rotation in this case. Production process of tap water enterprises are open construction, in the production process of water dissolved gas, at the same time in the construction process, the pipeline will be brought into the gas pipeline, if the exhaust valve is unreasonable, gas cannot be ruled out well. Thus, if the house does not use water for a long time, or the pipe design is unreasonable, the highest point or the starting point of the pipe in the house will have an air sac. As we all know, the compressibility of gases is very high. At this time, if there is pressure fluctuation on the pipe network, the space expansion in the pipeline will be very large, so the water meter will rotate more. According to statistics, the resulting water is less than 2-3 m3/ months, and more will produce dozens of cubic meters of water per month. According to the report statistics, the existing users reflect the water meter rotation of the phone 26, after field investigation and treatment found that because of the table after the airbag inside the house and the rotation of 21 households, accounting for 80.8%, after the pipeline leaking 5. Therefore, at present, most of the water meter produces rotation phenomenon, all because the back of the tube in the air bag caused.
- Q: What's the difference between installing vertical and horizontal water meters?
- The 2 watches are all the same except for the way they are installed. Mainly depends on how you design the pipe.
- Q: The water meter goes very fast
- If it's a single family, look for someone from the water company. You can show him these tests. Don't use the water bottle and the mineral water bottle. That's a standard volume
