Q:How much is the difference between the total water meter and the water meter?One month
1, the water meter will be sent to the relevant testing institutions to identify (in accordance with regulations, individual users can not change the water meter without permission, so it is not recommended to remove the water meter)2, close other pipes, leaving only a water pipe is connected with water, and then with a scale measuring cup with water, then compare the actual content and scale flow meter, water meter whether rough detection problem. Found problems, can to the local tap water companies or property companies to apply for replacement in a timely manner.3, you can count another water meter in the room to count and compare
Q:Who will be responsible for the leakage of water before the water meter?
This year, China promulgated the "property law" and clearly defined, water pipes before the leakage of water by the property responsible for the water meter after the leakage of water by households themselves.First, the landlord responsible for the wrong object, tap water company is a national, so whether it is before or after the tube tube shall be borne by the user to bear the cost, unless it is a public area or road pipe Water Leakage, so the landlord should promptly communicate and negotiate with the property.Second, when it comes to maintenance, if you do not have property in the District, and the water leakage in your home, then you must be responsible for your own maintenance costs, but you can not collect the cost of water leakage.
Q:The difference between a water meter and a flowmeter
The accuracy of electromagnetic flowmeter is high, generally can reach 0.5, ultrasonic flowmeter next, generally 1, and mechanical water meter accuracy is poor
Q:Must the new water meter be checked before use? Does the state expressly provide for it? In which regulation do you specify clearly?
Water meters belong to measuring instruments, and should be adjusted by the People's Republic of China metrology law.
Q:The role of water meters
An instrument for measuring water flow. The cumulative flow of water is mostly measured.
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:Why can the high level intelligent water meter be equipped with a check valve that can not prevent the water meter from idling?
The pressure fluctuations, because the water is a liquid, the physical characteristics shown in general is incompressible, but in the tap water pipe, pipe pressure is high, then the water will show some 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:Are the water meters and valves installed outdoors in a well? If so, how about before and after?
If the backwater pressure, then the general water meter also installed a valve, a check valve, to prevent backwater pressure, bad water meter. If the pipe is large, say, 100 of the pipe, a valve well should be installed in front of the water meter. That's all I know
Q:Who's in charge of the water meter?
The water meter is broken and the user of the meter is responsible.
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
