- Q:How do you steal water from a water meter?
- Another way is to move the base table, real electronic part, so that the base table word go slow, the electronic part is slow. The pipe clamp with large caliber, the sheet copper case to remove, open the lid, the impeller cut several tables inside, then installed reduction, or the water inlet of the impeller with a knife to open, the copper lid do not overexert, the glass will break. He can't see it, so you can use the fork to water. You don't feel so far, you have to worry about than you do then.
- Q:How to see the water meter?
- Direct reading water meter can be read directly from left to right according to the number of black instructions. The measurement unit is cubic meters (ton). The red indicator number can not be read.x0d.
- Q:There are two valves at both ends of the water meter. I know that the valve at one end of the water meter is a water valve. What's the other valve for? Open, there will be exhaust noise
- The front valve controls the pipe in the home for the user. After the table valve is the encryption valve, to use special tools to open. Maintenance water meter. Debt prevention.
- Q:Household card water meter, the house valve is closed, no water, water meter is slow rotation, what is the reason?
- That is, the water is flowing into your home, but you say that there is no leakage at home, you are prompted to check whether the water tank in the toilet is leaking or solar energy. If you can check to the places are not Water Leakage it should consider the connection pipe between home tap Water Leakage inspection methods, missed, get about one meter more metal pipe, home water, where you can see the top of the pipe to vibration where there will be the Water Leakage OOo on behalf of the closer, louder
- Q:What is a two meter water meter?
- The accuracy level of the water meter is divided into 1 grades and 2 grades.(1) the accuracy level 1 is only applicable to the common flow rate Q. More than 100m3 / h meter, accuracy grade 2 is applicable to all common flow Q. Value water meter.(2) for most water meters based on mechanical flow sensors, the accuracy level is 2.(3) in the national standard GB / T778.1 - 2007, the requirement of the accuracy grade 1 is not adopted.
- Q:If you put a magnet on the water meter or meter, will the water meter go slower?
- There are different reasons for the change of electronic energy meter and mechanical watt hour meter in the strong magnetic field. The reasons for the malfunction of the mechanical ammeter are similar to those of the electronic water meter. The electronic meter is currently used in the way, under the condition of high magnetic field is generally due to the strong magnetic field to the magnetic core of the transformer in the power circuit of the electric meter is magnetized, electric power circuit failure, not working properly, the meter is usually followed by a black screen, or other abnormal function, not the normal measurement meter. However, the new national standard has obviously been noted above, for the new national network, smart meters in this area has been added protection, and for magnetic field interference will record event records.
- Q:The difference between a water meter and a flowmeter
- The installation and maintenance of ultrasonic flowmeter is convenient, no process parking, and the other two are parking to install
- 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:Water leakage or water meter bad at home, regardless of how to do?
- If the owners Water Leakage inside their own Water Leakage, or Water Leakage upstairs, the owners should repair or maintenance of the owners upstairsThe classification of this situation:(a) if the warranty period, the developer should be responsible for maintenance;(two) if the warranty period has passed, the owner shall maintain it by himself.
- Q:How does a water meter work?
- Is actually very simple, because the water meter shell is fixed, the internal volume is fixed, and the water is flowing, it promotes a rotation of the impeller, the impeller when rotating a circle, there is a constant volume of water. Therefore, as long as the number of turns of the impeller is accumulated, multiplied by the constant volume, the total flow can be obtained.
