- Q: What's the unit of water for running water?
- Almost motionless. The word "m3" is also written on the scale, which means "cubic metre". That is to say, the unit of reading for this meter is cubic meter. Because every cubic meter of water is exactly one ton, the readings are straight
- Q: What does "IP68" mean in the standard of intelligent water meters?
- The second is the liquid protection level, in the range of 0-8, which represents protection from vertical water droplets to underwater pressure. The greater the number, the stronger the ability."IP68" is the highest level of protection for a water meter. Refers to the water meter can soak when long (electronic intelligent water meter for a long time to sink under the designated water pressure, can ensure that no damage caused by flooding).
- Q: Who is responsible for the lack of water meters leading to more water use?
- When we carry out water meter technical service work process, some users reflect the irregular meter when no water is still slowly rotating, mainly has three forms: one is the slow forward, stop and go; the two is now being transferred, the number of laps and reverse, turn circle is larger than the inversion, the total performance is forward; the three is near the water users, water meter along with rotation. Because do not know of these reasons, some users have doubts about the quality of water use.
- Q: How can one way water meter be controlled by one way?
- 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: Water meter rotation, turn off the valve will not turn, but did not find leakage
- This situation is basically leaking pipes inside the wall. There are two cases, one is the Water Leakage place, if such as wall and buried in the ground Water Leakage in the shelter, not found, another is the meter is broken, exclusion, to find someone to see whether the broken water meter.
- Q: What sort of water meters do you have?
- Displacement water meter: installed in a pipe, consisting of a number of water meters that are successively filled and discharged by a known volume of fluid and a fluid actuated mechanism, or referred to as a quantitative discharge meterThe displacement type water meter usually adopts the piston structureBy measurement gradeAccording to the old standard, can be divided into class a table, B class table, C class table, D class tableThe measurement level reflects the work flow range of the meter, especially the measurement performance under small flow. According to the order from low to high, generally divided into class A, class B table, C table, D table level scale, the measurement performance reached the corresponding requirements in national standard A, B, C class and D.After the new standard release, the measurement grade classification method becomes quite complex, mainly according to the flow value and the range ratio and other parameters to determine. In brief, the larger the measurement scale, the higher the measurement level
- Q: Which kind of water meter is more convenient for large-scale projects? The best engineering case can refer to
- For the newly built large-scale projects, the ordinary mechanical water meter has been unable to meet the modern management requirements. Intelligent water meter becomes the first choice
- Q: The differences between electromagnetic water meters and ordinary water meters, as well as their respective advantages and disadvantages
- First, the electromagnetic water meter needs electricity, and the ordinary water meter doesn't need electricity. Then the electromagnetic water meter does not need a water meter scribe. Finally, when the water is not enough, it will automatically bring you the water cut off, water can also use this card to pay.
- Q: The water meter goes very fast
- If it's a single family, look for someone from the water company. You can show him these tests. Don't use the water bottle and the mineral water bottle. That's a standard volume
- Q: The difference between electromagnetic flowmeter and electromagnetic water meter
- In essence, it is a kind of instrument, the principle and structure should be the same. The electromagnetic flowmeter is produced according to the flowmeter standard, the error (accuracy level) is executed by flowmeter, and the accuracy is higher. The electromagnetic water meter is produced according to the water meter standard, and the error (accuracy level) is executed according to the water meter, and the accuracy is low.
