- Q: What is the nominal flow of water meters?
- (1) the nominal flow rate of DN15 is 1.5 m3/h;(2) the nominal flow rate of DN20 is 2.5 m3/h;(3) the nominal flow rate of DN25 is 3.5 m3/h.Some water meters on the subject of "N2.5" refers to the "water meter nominal flow Qn is 2.5 m3/h", from which we can know that the water gauge's caliber is DN20. (nominal flow, some people are accustomed to commonly known as flow)
- 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: Which kind of water meter is more convenient for large-scale projects? The best engineering case can refer to
- The remote water meter solves the problem of meter reading to the household, and can monitor the statistical data of water use at any time, while the IC card water meter mainly solves the problem of charging and the control of the water consumption. Development units can choose their own products according to their own requirements.
- Q: Why should the water meter be horizontally installed?
- According to the regulations, the water meter should be installed horizontally, otherwise it will affect the accuracy of water meter measurement. Take an aperture 15 millimeter water meter, for example, at 1000 litres per hour, if the lateral slope is 45 degrees, the error will increase by 1%; the longitudinal inclination is 45 degrees, and the error will increase by 3%. At 180 liters per hour slow flow, the lateral slope of 45 degrees, the error increased to 5%; vertical tilt of 45 degrees, the error will increase to 20% or even greater.
- Q: Is the outdoor water meter smaller than the pipe diameter?
- An instrument for measuring water flow. The cumulative flow of water is mostly measured. Generally divided into the volume of water meters and speed water meter two categories. 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: The cause of the water meter's rotation
- This causes the rotation of the airbag, large amount of water. Tap water production process enterprise is 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 such well. If the family for a long time without water or pipeline design is not reasonable, the highest point in the home or pipeline will be produced. The airbag sudden starting point as everyone knows, the compressibility of the gas is very high, if the pipe network pressure fluctuations, after duct space expansion will be a great amount of water rotation resulting according to statistics, resulting in less water is 2-3 more than m3 months, there will be dozens of monthly cubic meters of water. According to statistics, the existing water meter rotation to reflect the users call 26, after the scene investigation found, Because there is an air bag in the pipe behind the table, there are 21 households that make the rotation, accounting for 80.8%. After the meter, the pipe leaks 5. Therefore, at present, most of the water meters produce the rotation phenomenon, all because the memory behind the tube is caused by the air bag
- Q: Is the check valve installed on the left or right of the water meter?
- Should be installed at the front of the water meter inlet, after the water meter problems better, easy disassembly! You got it right!
- Q: How to use the card water meter?
- Card type water meter usage: prepaid mode, that is, buy water first: water meter initial water availability is zero, the valve closed.
- Q: Why should water meter use batteries?
- You use a smart meter bar, water meter is divided into two kinds, one is direct reading type, one is both direct reading and can send information, you may use the latter, the inquiry function needs power
- Q: What should be paid attention to when installing water meter?
- Direction: position: the water meter can only be installed on the horizontal pipe, keep the dial level, and make the water meter shellThe arrow is in accordance with the direction of the flow. Do not install the arrow. Water meter should be installed before and after the valve, for the water is not allowed or not eliminatedThe pipeline construction shall also be provided with a by-pass pipe where the check valve shall be fitted at the back of the water meter and the valve on the bypass pipe shall be providedSeal.
