Miss Guangzhou can't read the water meter, so she simply gives it to the property according to the map. Do you know how to read a water meter?

On February 4, 65438, a residential property in Yuexiu District, Guangzhou required residents to write down the readings of water meters. Among the residents, there is a little girl born after 1990. Because she doesn't know how to read a water meter, she drew a gourd ladle and put it in front of her house for property inspection. Most netizens said that the little girl's behavior of carefully drawing a water meter was so cute.

In daily life, we often need to check the bases of a series of electric meters, water meters and gas meters. Some new dials are easy to see intuitively, but some older water meters will make people confused, and they don't know how to look at them, let alone how to identify them.

The premise of confirming the instrument is that we need to look from the front of the instrument, and we must not look from the side. When we look from the side, it is easy to be affected by the line of sight, which leads to meter reading errors. The water meter has four black needles, which are thousand needles, hundred needles, ten needles and unit needles from left to right. Generally, the red color on the water meter indicates the decimal point, which can be ignored in most cases, so we can only read the black pointer when reading. When the black pointer is between two numbers, we only need to read the decimal places, which is the same as the reading method of clocks and watches. When reading, we can read from high to low in turn.

Each of us has different cognitive fields, and it is certainly impossible to master all aspects of life, such as this water meter or gas meter, if not. It's also lovely to take pictures and give them to professionals to answer, or draw them like that lady. Of course, there is a lot of other knowledge that we don't know. Just like a layman, we all say that interlacing is like a mountain. When faced with knowledge we know nothing about, what we can do is. If finding small problems can't solve big problems, then leave professional things to professional people. It is better to master more knowledge, but if you can't master it all, it will make life easier.
