- 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: 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: How many parts does the water meter consist of?
- The internal structure of the traditional water meter of the traditional water meter from the outside can be divided into shell, sleeve, inner core three pieces. The shell is cast iron, water from the water inlet out through the lower part of the annular space of the shell, it is called "annulus".
- Q: If you put a magnet on the water meter or meter, will the water meter go slower?
- The conventional electronic water meter usually adopts the method of measuring the water consumption of the dry reed tube. Under the strong magnetic field condition, the reed pipe is always in the "double pull in" state and can not be measured normally. The electronic part of the water meter can not be used. But for the mechanical part is generally not affected by the mechanical part measurement generally normal, even if there are problems will take a mechanical part as the standard, and the added magnet interference, electronic parts usually have checked out interference records, may face a fine.
- Q: Which is better, dry water meter or wet water meter?
- In most parts of the south, it is more suitable for wet water meters, because the climate there is warmer in winter, and the water quality is soft, not easy to scale, it will not affect the long-term normal use of water meters. In the northern part of the country, especially in the colder winter areas and the more difficult areas of water quality, it is more suitable for dry water meters. Because the counting mechanism is isolated from the measured water, the phenomenon of copying is not affected. And dry water meter in a cold climate, its working stability and security is also significantly higher than the wet water meter.
- Q: Is there any deviation in the water meter measurement? Why?
- The problem of water gauge over time: water meter should be checked regularly and replaced at maturity. (1 meter) when in use, the rotation of the impeller and the top friction frequently, while the top is an important component of water meter support within the rotation of the impeller, which is the result of a top wear between the top and the impeller friction resistance increases, the water meter is negative; two impeller position decreased, increased between the impeller and the impeller box resistance decreases the water meter is partial. (2) in water use, due to non-uniform distribution of water meter, water flow flows through the impeller inlet box side flow is greater than the water outlet side, one of which is that the middle and top impeller impeller sleeve frequent friction, tilted to the side edge of the water outlet, impeller and impeller parts box wall close, increasing resistance at the same time, the impeller diameter by grinding, water impact on the impeller torque is small, the water meter is negative; two upper middle and upper impeller sleeve is inclined to the water outlet, the upper splint sleeve is frequent friction, into an oval, the impeller axial shift, wear between the impeller shaft and gear box, to make the resistance increase also, partial negative water meter.
- Q: What are the advanced water meters?
- Intelligent intelligent water meter in addition to the use of water for the record and electronic display, can also be in accordance with the contract to control the use of water, and automatically complete the price ladder of water and water can be calculated, the data storage function. Because of its data transmission and transaction settlement through IC card, and thus can be achieved by the staff from the table to collect fees to the user's own business to pay the change. IC card trading system also has the characteristics of convenient transaction, accurate calculation and bank settlement.
- Q: How do you connect the water meter with the PPR tube?
- Make sure the caliber of the metal pipe you use is generally available on the pipe wall. In addition, the metal pipe needs to pay attention to two points: 1. the caliber of the metal pipe is marked with the inside diameter (the outer diameter of the PPR pipe is marked); and 2., the metal pipe joint that is left by the notice has a thread used to connect the PPR pipe.
- Q: Why doesn't the water meter turn around?
- The pipe is in air and cannot be ruled out. As the pipe network maintenance, disassembly and water meter when water supply is stopped, the air into the pipeline, stay in the pipeline is not common; especially some users network will not change the line, pipeline, tap water before the blocked, and the internal pressure imbalance, causing water to move.
- Q: The new rotor type water meter, in dripping water, if the drip is very slow, for example, 10 minutes a drop, the water meter will turn? Do not know the reason, please do not answer, please explain the reason!
- The new meter adds a cavity in the bottom case, and is connected with the water outlet, the middle with a soft diaphragm separated, and adding a valve at the outlet, when the outlet to drip out water, down to the deformation of soft membrane in the inlet pressure under the action when the water reaches a certain amount, drip proof device will open the outlet pressure, so as to drive the impeller to rotate to measure the effect process of water supplement is intermittent, measurement in the process of water leakage is intermittent. When the normal water valve, the sensor will follow the open, so that the water becomes a completely ordinary water meter.
