- Q:How can water gauge be installed on cast iron pipe?
- According to the cast iron pipe is a large-scale water meter water meter, water meter diameter is more than 100mm for flange connection, meter mating flange 2, both ends of welding tube, making the sleeve and flange cast iron pipe welding tube connected to a good amount of water, length of the plus ends of casing (casing mouth), cut the cast iron pipe two the sleeve flange on the cast-iron pipe with good water, in the adjustment of casing pipe and cast iron pipe gap can be cracked.
- Q:The cause of the water meter's rotation
- 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 exhibit compressibility. In some tap water in the pipeline, the pressure fluctuation is inevitable, and we 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 measuring water. 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, after the table in tap water pipe the volume shrinks because of increasing 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 is compressed by water pressure decrease and the expansion, will also have a trace of the water through the water table, the difference is This is the reverse. 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 reflects the reading on the meter is in great. According to statistics, in the case of no air pipeline, resulting in less water, about 0.5-1m3 months. Usually, this water users do not pay attention to; at the same time it is also the current measurement level under normal results.
- Q:What's the tool for changing water glass?
- Don't need a professional tool, of course to remove meter independence from in the pipeline, is the need to use the wrench, pipe wrench (general household recommended 14 inch, up to the maximum opening, which is to be opened, just barely enough clip header, just can clamp meter above the head, this clip is the most convenient on both sides of the connecting tool etc.). Here comes the need for water meter installation pipe clamp is said in aluminum pipe hose pipe, if the meter is installed in the galvanized iron pipe, does not need the pipe clamp, removed when only one 12 inch wrench.
- 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:How do I reverse the digital water meter?
- The first type is the ordinary mechanical water meter, drip proof water meter and so on
- Q:The water meter goes very fast
- I remember so, and see if there are any other wordsThose who seek to rent your house should be the responsibility of the water company, and they will pay for itCollective is not easy to say, you can not buy your own standard, that is to say, you are also likely to buy a problem, which should belong to the building materials categoryBut should be able to find you rent a house, you rent a house, ownership is not you, because of his water problems caused by your monthly pay. Do not know if this count does not count, anyway, I have a friend to rent a house, there is no air conditioning, he insisted that the owner bought an air conditioner, is similar to I feel the truth
- 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:How do you calculate the water meter inversion?
- In short, the problem of water table rotation, although the national standard says that the water meter rotation within a certain limit is allowed, but the inverted water meter is completely uncontrollable. At present, only control to avoid the occurrence of water meter rotation, such as the installation of exhaust valve and check valve, so as to maximize the water meter to avoid rotation.
- 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.
- Q:How much is the difference between the total water meter and the water meter?One month
- At present the state error range of tap water meters not more than plus or minus 5%. if after testing is indeed the total water meter, the company will replace the tap water meter, and filled the user fees. If the water table, suggest the user to replace the table, to avoid losses.
