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:How does water meter read m3? What does it mean?
The metering unit for the cubic meter (M3), because the density of water is 1 cubic meters =1 tons, so 1 cubic meters is 1 tons. Cubic meters of water below can not indicate the number of records in this month, indicating meter minus the number that indicates the number of water meter last month, this month practical content.
Q:What are the sizes of the water meters in general?
General household water meter caliber: 15mm, 20mm, 25mm, 32mm. 15mm and 20mm mostly, there are a small number of 25, 32 of water meters, water gauge caliber depends on the size of the installation of the pipe diameter, that is, usually 4 points, 6 in charge.
Q:New home installed a smart water meter, do not know how to see how much water has been used, ask for advice!
The electronic part of the smart meter is generally do not show water, need you take a user card reader operation, electronic liquid crystal display part displays the total amount of water, the actual water consumption and surplus water etc.. The above information is not for long-term display purposes, but also in order to save electricity, increase or decrease the water meter, battery and table life.
Q:Why does the water meter need the valve before and after?
After the water meter, the valve is set for easy use.
Q:The role of water meters
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 does Hua Xu IC card intelligent water meter sound for long time?
There may be little money left! If it is prepaid IC card water meter, there may be no battery! The problem is to understand what type it is! To make a judgement!
Q:How to solve the water meter inversion?
Is the first flip meter, you can purchase some manufacturers like watch in the water known as anti flip artifact known as the water heat shrinkable film tamper device, only need to install the meter when it will be set in the pipe above, with hot water or hair dryer blowing, will be good fit to take over, if to remove the table must be broken flip heat shrinkable flexible membrane, which is a kind of effective method. The second is simply the problem of water table rotation, although the national standard says 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, for example, you can install the exhaust valve and check valve, so as to maximize the water meter rotation.
Q:Which factors are important for water meter selection?
This is especially important for large bore water meters. As a result, water meters (such as removable water meters) that can be installed, replaced, or maintained without water are capable of meeting these requirements. Install water meter length and connection mode is also a factor to be considered, although the water meter national standard GB/T778.1-1996 in Tables 1 and 2 have provided this requirement, implementation of the standard meter manufacturing the same type in the installation and connection length. But in recent years, some new water meters (including prepaid intelligent water meters), some are not according to national standards, but by enterprise standard manufacturing, this may be different.
Q:Please tell me the accuracy level of the water meter
Accuracy level and measurement level of water meterThe accuracy level and measurement level of water meter are two different concepts. The accuracy grade provides the indication error limit of water meter, and the 2 stage indicates the maximum indication value of water meter, and the error can not exceed 2%. The new procedure has 1 meter water meters, but it must be marked on the water meter.
