- Q: What's the unit of water for running water?
- So the water can be conveniently according to the total water readings (tonnage) calculated.
- 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: Who is responsible for the lack of water meters leading to more water use?
- The pipeline pressure fluctuation. Water as a liquid, there can be compressed in water supply pipeline pressure is high. The pressure fluctuation is inevitable in tap water pipeline, when the pressure of the main network rises, after the water in the pipes because of increased pressure and volume reduced, this will have the trace of water through the water table generation is transferred, inversion pressure net charge reduced. Because water resistance is greater than the internal gear is reversed when forward resistance, even if the same amount of two water meter, water meter is reflected in the reading on the will also have differences, the total performance is positive.
- Q: Look, you've answered the water meter. Please consult me. See if my house is leaking or something else?
- If a check valve is installed and the water meter does not turn, then the water in the home pipe does not leak. The water meter idling is caused by the air in the pipe. After the check valve is installed, the water meter will still rotate if the inside pipe or facilities are leaking.
- Q: How to buy a water meter
- If you don't understand it, say "1", the more the better. 2 table covers and watch fittings must be copper. 3, go to the local water company to buy the best.
- Q: What's the difference between installing vertical and horizontal water meters?
- Water meter is divided into horizontal and vertical horizontal type water meter installed in horizontal straight pipe for horizontal water meter water meter water meter vertical place a little small toilet is not suitable for the horizontal pipe (pipe to erect up, is a head, a head down, the direction of fit) where general bathrooms in the small space is relatively small installed in the corner for the building exterior ground now also use the vertical water meter
- Q: Please tell me the accuracy level of the water meter
- Measurement level is divided by the demarcation of the water gauge and the minimum flow rate to characterize the sensitivity of the water meter. The old rules are graded according to A, B, C and D, and the D level is the highest requirement. New procedures, dosage, process ratio (Q3/Q1) to replace the original level of measurement, the ratio of at least 20 options, the greater the ratio, the higher the requirements, the greater the difficulty of manufacturing. The Q3 and Q3/Q1 values of the water meter are determined by the manufacturer according to the market demand, and must be clearly marked on the water meter. When the water meter is checked, the flow point can be chosen according to the value indicated on the meter.
- Q: What are flanged valves and flanged water meters?
- Valves and water meters connected to pipes using flanges and bolts;General diameter (caliber) larger, small caliber valves and water meters are generally threaded and pipe connection.
- Q: Why doesn't the water meter turn around?
- User small flow drop. Many users believe that a drop of water will not measure, but the water pressure caused by dripping water is lower than the pressure of water supply, which leads to pressure fluctuation and the water meter is slightly changed.
- Q: How does Hua Xu IC card intelligent water meter sound for long time?
- There may be little money left! If it is prepaid IC card water meter, there may be no battery! The problem is to understand what type it is! To make a judgement!
