Household gas meters are not the same for all households, it is also divided into several specifications, in addition to the manufacturer information, the appearance is different, there is an important point is that its gas supply capacity is different, the general household has three specifications G16、g2.5. G4, not to mention that if it is a gas meter of three specifications of the same manufacturer, its appearance is really similar, so how to see that your own gas meter is 16 or 2What about 5's? How are these specifications used? Is there the smallest fire in the house?
Let's uncover the relevant questions.
1. How to distinguish the model of household gas meter?
The model of the household gas meter can be clearly distinguished by looking at the front panel of the gas meter, such as the gas meter below
It has a string of letters and numbers above the wheel: CG-L-G25, then this gas meter is 25 gas meter, and then look at the lower part of the wheel also have letters and numbers, where qmax 40m3 h, which represents the maximum permissible gas flow rate of 4 cubic meters per hour.
Then the gas meter is as follows:
Look at the first line at the top of the gas meter, membrane gas meter sc300 g16, which means 16 gas meters, we are also able to see its qmax 25m3 h, which means that its maximum allowable gas flow is 25 cubic meters per hour.
The same way to view the gas meter of G4, we will not list it.
So the question is, why do we need to produce so many models of gas meters? Does the fire in your own house have anything to do with the amount of gas passing through the gas meter?
2. The difference in the size of the gas meter.
The size of a gas meter does not refer to the volume, but to the maximum allowable flow rate. Just now we said 16 and 25 gas meters, while for G4 gas meters, the maximum allowable metered gas flow is 6 cubic meters per hour.
The main reason why there are three models of gas meters is that they are used to meet the needs of different users. For example, if the user has a binocular stove at home, even if both eyes are 5With a large fire power of 2kw, its maximum gas consumption flow is only 15 cubic meters per hour, just use 1The gas meter of 6 is just right. And if the user's home is equipped with a dual-eye stove and a gas water heater is used together, the water heater is calculated as 2 cubic meters per hour, so it adds up to 35 cubic meters per hour, so use g25 gas meters. Similarly, some users are equipped with gas wall-hung boilers for heating at home, so they use G4 gas meters.
The reason for this is that the maximum allowable flow rate is different for different gas meters, and the closer the flow rate is to its rated flow, such as 1The gas meter of 6 is rated at 16 cubic meters per hour, then the more accurate the metering.
This is also the difference between the three models of gas meters, that is, the flow rate allowed to be metered is different. If you have a wall-hung stove and a binocular stove, you are using G16 gas meters, then it is a small horse-drawn cart, can not be pulled, the measurement is not accurate, some gas meters may report errors. The same only one double-eye stove, but the installation is a G4 gas meter, then it is a big horse-drawn trolley, a waste.
In addition, the small fire at home has little to do with this gas meter, the biggest factor affecting the gas transmission volume of household gas is the pipe diameter, and these three models of gas meters only represent the size of the gas flow rate that can be accurately measured, rather than the size of the circulation. Therefore, the fire is large and the fire is small, and the gas meter is 16 or 25 It doesn't matter.
So, do you understand? Here is also a reminder to friends, for the size of the gas meter, we should not be too entangled, this is a matter of professional and technical personnel of the gas company, anyway, their own family is not enough, it is right to find them.
