Both new water meters and natural gas meters directly read the numbers in the grid (similar to electricity meters), and read them from left to right according to the numbers. Some decimal points of this instrument also directly read the numbers in the grid, which are generally marked with ×0. 1 above the grid (mostly in red), and some decimal points are displayed by the pointer, which will be marked with red ×0. 1 below the pointer.

Old-fashioned water meters are all displayed by hands, and there are units, hundreds, thousands, one decimal place and two decimal places under each hand. For example, one hundred digits write × 100, and ten digits write × 10, and multiply the number by the corresponding digit value pointed by the pointer. For example, the pointer corresponding to x100 points to 5, on x10 the pointer points to 3, and the pointer points to 2 x 0.65438.

Normal state of natural gas meter

1. First of all, all smart gas meters have LCD screens, which will display the valve status, remaining gas volume, total gas purchase and other information of the gas meters. The number of remaining gas volume in the instrument is often displayed on the LCD screen, and the remaining two words are usually marked in front, and the unit is cubic.

2. If the display is 26.8, it generally means that there is still so much residual gas in your meter, and all smart meters have the residual gas prompt function (different brands may set different values, most of which are around 10 cubic meter).

3. When the residual gas is insufficient, there will be a prompt sound or a reminder function will be displayed on the LCD screen. At this time, it is necessary to inflate in advance according to the situation.

Outside the gas meter, you can only see a drum with numbers in the small glass window. There are also seven digits on the drum, the first four decimal places are black and the last three are red.

Traditional energy has been transformed into clean energy such as natural gas and gas, and even electricity. Here, the gas meter will play its role. With its automatic accumulation function, people who use natural gas or pipeline gas can easily know how much gas is used, so they can pay according to the number of cubic meters of gas used each month.
