The black wheel is called the mango needle It is used to measure the flow rate when testing (that is, how much the flow meter will go Generally, DN20 is not more than 12 liters per hour, and the new meter is generally about 7 liters, and DN15 is generally not more than 5 liters) The integer is the number that reads the scroll The decimal places read the four red wheel rings, clockwise are, such as the pointer between 4 and 5 Read 4 The others are like this Enough detailed It's not even a score Hehe.

Water is indispensable for human beings, but many people wonder how to measure water meters in their lives, so let's introduce the method of looking at water meters.

The last digit or digits of the word wheel are red, and as with the red pointers, we can choose not to look at them.

Take the black word wheel reading:

100,000 bits: 00,000 bits: 0

Thousand: 0 hundred: 0

Ten digits: 1 bit: 1

Red letter wheel: 6 (we ignore it).

Reading the red pointer part: The reading of the red pointer is used for factory inspection, and we don't have to care.

The result: 11 tons.

The way pointers are displayed.

Take the black pointer reading:

Thousands (1000): 2

Hundred (100): 2

Ten (10): 6

Unit (1): 1

Take the red pointer reading: The reading of the red pointer is used for factory inspection, and we don't have to care.

The result: 2,261 tons.

Note: Attentive readers have noticed that we don't care about the red pointer, but the black word wheel or what the black pointer shows is.

A common combination of word wheel and pointer displays the reading.

Take the black word wheel reading:

10,000: 0,000: 0

Hundreds: 0 Ten: 0

Single digit: 1 read the red pointer part: the reading of the red pointer, used for factory inspection, we don't have to care.

The result: 1 ton.

The way the water meter displays the readings is generally that the water meter displays the readings through a combination of a black word wheel and a red pointer. The structure of the reading display is generally that the reading consists of a black word wheel and a red hand. The black word wheel generally displays integer digits, and we only need to read the numbers on the word wheel, and the reading on the pointer is used for inspection when the water meter leaves the factory.

The reading of the red hand is also used for factory inspection, so we don't have to care.

The unit is cubic meters, starting from twelve o'clock, that is, the largest word is more than one digit, the figure is 591, and then clockwise start each submeter minus one digit, in turn is the tenth digit 3, the percentile 6, the thousandth 7 and the ten-thousandth 0, so the number of this table is.

Looking at the dial, it is generally in the form of a word wheel + hands. Black is an integer and red is a decimal place. So, you try it and see if you can read it. The same is true of the all-pointer type.

1. The red water meter is generally the decimal place, and the black is the integer digit, starting from the x1000, x100, x10, and x1 of the black wheel, which are thousands, hundreds, tens, and single digits. For example, the X100 file is 2, the X10 file is 5, and the X1 file is 7, then the reading is 257 tons. For example, the pointer of the x10 file is in the middle of 2 and 3, then the x10 file is 2, and the other files are the same.

2. First of all, look at the kilotonnage, because the pointer of the kilotony is between 0 and 1, so the reading of the kilotonnage is 0.

3. Then look at the 100 tonnage, because the 100 tonnage pointer is between 7 and 8, so the reading of the 100 tonnage is 7.

4. Finally, look at the tonnage, because the pointer of the tonnage is between 8 and 9, so the reading of the tonnage is 8.

5. After the above steps, we can conclude that the tonnage of the water meter is 768 tons.

The water meter is viewed from left to right, and the numbers on the left are the high numbers, such as thousands, hundreds, tens, units, tens, percentiles, so that you can record a set of numbers, and by next month, subtract the previous numbers, and you will know how much water is used.

00231,231 is the number of tons, and the rest are decimals, it doesn't make sense to read or understand, and it's more than 3 yuan for a meal.

Don't look at the number on the hand in the water meter. Just look at the row of black numbers below.

I'm going to watch it together with last month.

There are a total of 8 digital hands on the dial of the water meter, 4 of which are red and 4 black, and the reading is measured in cubic meters. The red hand indicates less than 1 cubic meter, which represents the reading after the decimal point and is generally not read.

In the black pointer, "1" represents a single digit, "10" represents a ten-digit number, "100" represents a hundred-digit number, and "1000" represents a thousand-digit number. The pointer of each stop, if it is between two numbers, reads the previous number.

For example, the thousand needle is between 1 and 2, read 1; The hundred-digit needle is between 5 and 6, read 5; The ten-digit needle is between 1 and 2, read 1; The unit needle is between 3 and 4, read 3.

Different water meters have different ways to see, if it is a water meter with a combination of numbers and pointers, open the protective case, and only need to look at the black word wheel when reading; If it is a pointer water meter, open the protective case, and the number indicated by the black pointer is the amount of water used. The pointer water meter is copied from the left pointer and read the pointer one by one to the right in turn; The digital water meter is also copied from the number search on the left, and copied one by one to the right in turn, but the red leakage trillion number is not copied.

Data Extensions. Water meter, is to measure the flow of water instrument, most of the water cumulative flow measurement, generally divided into volumetric water meter and speed water meter two categories, originated in the United Kingdom, the development of water meter has a history of nearly two hundred years, when choosing the size of the water meter, should first estimate the size of the flow and the flow range used under normal circumstances, and then choose the commonly used flow closest to the value of the size of the water meter as the first choice.

How to install the water meter.

1. The caliber of the water meter should be determined according to the caliber of the installed pipeline, and the installation location should avoid exposure, flooding, freezing and pollution, and the cluster rent should be convenient for disassembly and assembly.

2. The water meter should be installed horizontally (display facing up).

3. Before the new installation, the sand, gravel, hemp and other debris in the pipeline should be removed to avoid water meter failure.

4. The direction of the arrow shown in the water meter should be consistent with the direction of the water flow of the pipeline.

5. If the water meter is installed at the water inlet end of the boiler, it is best to install a check valve at the outlet of the water meter to prevent the boiler hot water and steam from backing up and damaging the internal parts of the water meter.

How should the water meter be seen, I believe that many friends are very interested in this issue, and the following will give you a detailed introduction.

1.The general water meter will have a protective cover on the dial, and when checking the water consumption on the water meter, the cover should be lifted first.

2.There is a rectangular window on the water meter, which shows the number of the total current water consumption. It is marked with m at the back, which means that the unit is a cube, and the current total is subtracted from the previous total, which is the water consumption in the recent period.

3.Although some water meters have different shapes, they generally have a small window that shows the number, and then marked with m, which is the total water consumption; 1 cubic meter of water is slightly equal to 1 ton of water, so you know how many tons of water are used.

4.In the water meter, there is a black round gear-like thing, this general change is the water flow indicator wheel, when the water is released more stupidly, the faster the indicator wheel will rotate, when the indoor faucet is all closed, the indicator wheel also rotates for a long time, that means there may be water leakage.

5.In the water meter, there are some small pointers, mainly for more accurate reading of water consumption, can be accurate, generally look at the water meter mainly to see the numbers in the top small window.

Next to each pointer is an x? ，？1 is a single digit,?

10 is a hundred,? It is the decimal ......And so on. All the numbers together are the current meter readings.

Subtract the last reading and that's the amount of water used between meter readings.

It is the reading in the rock collapse mold map, and the display of 7 of them is unclear, and it is estimated that it is read.

This one is 9m, it's not. Because there is no decimal point on the meter, and the top pointer is marked next to it, it means that the pointer is, and the reading should be.

Unless you are sure that the water representation is 0 when you start renting, you will not be able to see how much water you have used in the past 12 days from this picture alone, and this reading minus the initial reading when you first started renting is the amount of water you have not used during this time.

1: Water meter with number and pointer display: the common combination of word wheel and pointer displays the reading, and reads the black word wheel reading.

2: Display water meter with pure pointer: read the black late wilt pointer.

3: Pure digital display of water meter code hole: the last digit or digits in the word wheel are red, the same as the red pointer, we can not look at these digits. Take the black word wheel reading:

Note: The red number is not read when reading the water meter water consumption. From right to left, the black display is: one, ten, hundred, thousand, ten thousand.

When reading the water meter water consumption, the number or pointer is between 1 and 2, and only 1 is read! And so on.

Regardless of whether it is a word wheel or a pointer water meter, black indicates an integer and red indicates a decimal number.

It should be read from left to right in the same way as the reading, and generally the black numbers are the integer part of the reading.

Black characters, from right to left, are one, ten, hundred, thousand, and ten thousand.

If the red gear is the starting point, then the tonnage is added to the last digit of the black number.

Also look at the water gauge dial, is it the beginning, or, if the red gear is, then the black number is the tonnage.

The decimal part is not as good as the part, so it does not have to be read.
