- Q: Why must water meters undergo strong inspection?
- Quality supervision department staff explained that this is because with the increasingly shortage of water resources, water costs continue to improve, the accuracy of water meter measurement more and more attention to the masses. In addition, if the water meter is not maintained and maintained for a long time, the accuracy of its measurement can not be guaranteed.
- Q: What about rust on water meters?
- Rusting and scaling in the table are caused by many reasons such as rusting of pipes, etc., which occur in the extended use of water meters (the State stipulated that the water meter should be used for 6 years). In this regard, it is recommended to replace the water meter or to re clean and test the old water meter.Or to call their business, complaints, water companies will come home processing, costs are not responsible.
- Q: What is the metering rate of a water meter?
- Explanation: most countries in the world require the use of water meters that can reach the level of B or more. In the domestic industry, there is also a call for the abolition of water level meters with measurement grade a..
- Q: How do water meters clean scale?
- It is not allowed to disassemble the water meter, problems can be found in direct contact and water, need to replace the replacement, do not deal with their own, this is not allowed in practice, a. If they are not installed, you can first turn off the main valve, cover the table open, brush along the edge of the brush, brush, and then tighten the lid.
- Q: How much is the water meter at one time?
- 1 =1 =1 * 1 kwh kilowatt hour =1000 watt hour is 1 x 1000 watts (W) electric appliances with an hour of electricity is electricity. If it is 65 watt (W) with electrical appliances for one hour is 1 hours: 65 w * =0.065 * 1 kW =0.065 kilowatt hour when the =0.065 of electricity. In 15.4 hours to use electricity.Energy is the unit of energy, Watts is the unit of power, can not be converted, but 1 kwh =1 kWh
- Q: My water meter in the absence of water, water meters on their own table?
- GasbagThe reason for this is that the amount of water generated by rotation is greater. 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: 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: What's the size of the household water meters?
- Household water meter is usually 15 or 20 caliber majority, there will be a small amount of 25, 32 of the water meter, water gauge caliber depends on the installation of the pipe diameter of the house, that is, usually 4 points, 6 in charge.
- Q: Why is there so much water in the water meter?
- It's not water! It is mechanical oil to prevent corrosion in table!
- Q: How do you connect the water meter with the PPR tube?
- PPR pipe fittings, there is no set of silk said, you this statement may be the local saying. There are two kinds and four kinds of conventional direct silk thread parts:Outer wire tap (as follows)The wire connecting (below)Outer filament direct (as follows)The wire directly (see below)Specifications, products or external packaging are marked, please pay attention to must buy silk pieces, because it is more expensive than pure plastic oh.
