- Q: Has the number of water meters been accumulating? Should the water use of this month be reduced by last month? Will it be cleared?
- Will not be cleared, for example, in January the water meter readings 1120, February degree 1150, then this month the amount is 1150-1120=30 (ton)And the degree of each month will be recorded, do not be afraid of mistake, and now the management is very scientific and technological
- Q: Just renovated house, no water, water meters will turn? What's the reason?
- The water pipes are empty, the air will "take advantage of a weak point; when the recovery water, the water pipe of the air pressure to the indoor pipeline all the blind end, the formation of" compressed air ", until the air pressure and water pressure balance so far. There is an interface between gas and water, when the pressure difference between the two sides of the interface is zero; and when the water pressure changes, the two sides of the interface form a certain pressure difference, and the gas and water balance is destroyed. To compensate for this pressure difference, to reach a new equilibrium, must change the pressure of the air, causing air volume expansion or contraction, thereby causing the pipeline "connector" in tap water flow, so the "idling" phenomenon is produced.
- Q: How do water meters clean scale?
- Go to the daily necessities store and buy some oxalic acid to wash it. That's OK
- Q: Is the flow meter the same as the intelligent water meter?
- Conductive liquid (tap water because of containing conductive ions in water, so electromagnetic flow) can flow through the magnetic field, cutting the magnetic lines, and generating induction potential.
- Q: How to deal with leakage of water meter?
- To see whether it is the tap water meter Water Leakage trading settlement meter, if it is, then you can call the local water supply service hotline, the replacement is free, if not installed the tap water company trade settlement meter, then contact the property or to replace the line
- Q: How long can the smart water meter battery work?
- At present, the average static current of water meter module is below 3uA, and the total power consumption is about 970mA in 6 years. (the flow of valve switch is about 80mA/9s). This is only theoretical value, and there is no question about it. And if the pipe network is in the state of pressure (0.4Mpa), the current of the switching valve usually needs more than 90mA.
- Q: Problem of water meter joint
- If you twist it, twist it out of the linen or raw tape, if there is no hemp or raw tape
- 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: Do you know the working principle of dry water meters?
- The water meter is divided into a wet type water meter, a dry type water meter and a liquid sealed water meter according to whether the counter is immersed in water.
- Q: How can I distinguish water meters from dry ones?. Still wet?.
- The biggest difference between dry and wet meters is the metering mechanism. The impeller is separated from the central gear, and the upper end of the impeller is coupled with a magnetic component at the lower end of the central gear by a magnetic component (magnetic ring or cylindrical magnetic steel). When the water flow to drive the impeller to rotate, the magnetic element lower magnetic element and the upper end of the impeller center gear to attract or repel, driving gear synchronous rotation and drive from the center of the water passes through a water meter counter.
