Q:Why is the water meter always called?
If the battery of smart water meter is out of power, the meter will appear.
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:Can the figures on the water meter be changed?
Remove the table: find a water unit worked in friends, help to remove the table, unscrew the four screws inside the stopwatch readings, then put on a table, this number on the meter will turn very slowly. Do not advocate this method, because this is in violation of the household water convention, and do not understand the demolition of the table, it is easy to damage the water meter.
Q:Where is the backflow preventer installed?
Tap water network access to the user's home, the pipe behind the meterThe domestic water pipe is connected with non living water and sewage pipe, and is installed at the end of the pipe.The inlet pipe of the drinking water tank (when the tank bottom is flooded).When drinking water pipe is connected in series, the pressure pump is installed on the suction pipe of the pump.
Q:Which direction is the switch for domestic water meter?
It's a watch side valve. Generally speaking, the counter clockwise is open. Be careful not to force too much, easy to spool broken.
Q:Learn readings for meters, water meters, and gas meters
Magnification is the measurement multiple formed by the transformer and the traverse through it (for example, a 150/5 mutual inductor leads through it, 1 times the magnification is 30, passes through 2, the magnification is 15, passes through 1 of which is 10)
Q:What should be paid attention to when installing water meter?
Make sure the installation site is: water meter is installed in view, convenient, free from exposure, cold and non polluted,A water meter generally introduced into a pipe is mounted in a chamber, an external well, a well, a basement or a private room. Small water meter for household useOn the inlet manifold of each production. Water meter should be preceded by the valve, water meter shell from the wall may not be greater than 30mm, water center from anotherA wall (end) distance of 450 ~ 500mm, the installation height of 600~1200mm. To ensure the measurement accuracy of water metersIndeed, the upstream end of the screw wing type water meter shall have a linear pipe section of 8~10 times the nominal diameter of the water meter, and other types of water meters shall be front and rearA straight line section of not less than 300mm. When the length of the straight pipe before and after the water meter is larger than 300mm, it is applied beyond the pipe sectionHead led to the wall, along the wall laying, the center of the wall from 20 to 25mm.
Q:How do you adjust the water meter?
To the back, you have to turn off the water, remove the seal, remove the glass cover, and then pull out the pointer to the original reading, but if you secretly this involves stealing, but to consider well.
Q:Does the water meter battery affect the water meter?
Intelligent IC card, mechanical water meter or intelligent remote mechanical water meter or intelligent water meter, ultrasonic water meter, electromagnetic water meter and so on
Q:Can the pipe behind the water meter be changed in diameter? Is there any regulation that can not be changed behind the water meter?
The surface of the water meter is less than 0.2m after the surface of the water is lower than that of the other, so that it can be copied easily.
