How do you look at a digital water meter? How to look at the numbers on the meter and how much water

Water meters have made their way into homes, but many people can't read water representations correctly. Many of the water metering complaints received by the metering department of the water supply company are caused by misreading and copying the water indication value. The following is a brief explanation of the type of water meter and how to read the water meter.

Pointer water meter.

There are two types of civil water meters: one is the pointer type. The dial is composed of four black hands, four red hands and one plum blossom-shaped hand, and only four black hands are read when the user checks, and the other hands are only used for water meter verification.

Jump-type water meter.

Another type of water meter is the jumper type. Its dial is composed of five jumping characters, three red hands and one plum blossom hand, and the jumping word dial is composed of four black letters and one red letter.

The reading method of the pointer water meter is similar to the reading of the clock, which is clockwise, the difference is that the water meter adopts the decimal system, and each pointer has its own dial, that is to say, the single needle rotates for a week, and the ten needles only go one degree, which represents 10m3 of water, and the ten needles rotate for a week, and the hundred needles go one scale, indicating that 100m3 of water is gone. Therefore, like the hour, minute, and second hands in clocks, the previous digit is read when the next hand is not full tick. If the pointer deviates too much, it is due to the transmission gear clearance or damage to the transmission gear.

In the second case, the water meter can be removed and repaired to the metering room of the water supply company.

For skip-the-word water meters, only the valid value of four digits in black is read, and the other pointers are only used for water meter inspection, and the user does not need to read them.

10 tons. The numbers add up one by one, and the red pointer is the number after the decimal point. Your watch should have used a ton.

Hope to help, brother is in urgent need of an upgrade.

The three sets of numbers in the water meter correspond to thousands, hundreds, tens, and units. When looking at the water meter, you first need to look at the thousand word wheel, and the thousand word wheel pointer is located between 0 and 1, so the thousand tonnage is 0. Then look at the hundred-digit wheel, the pointer of the hundred-digit wheel is between 7 and 8, so the hundred-digit tonnage is 7.

Looking at the ten-digit word wheel again, the pointer of the ten-digit word wheel is between 6 and 7, so the ten-digit tonnage is 6.

The first 4 digits in the water meter are black, all of which are displayed as 0, indicating that the water consumption of the meter is 1 ton, and the 5th digit is a red 3, which means that the water consumption is a ton. The three red pointers below the water meter represent three values.

Common sense in the use of water meters

The specifications of the water meter should be based on the common flow rate, and the diameter of the water meter cannot be determined by the pipe diameter alone. The water meter should not be used for corrosive liquids, and the cold water meter is not allowed to enter hot water. It is strictly forbidden to leave anything above the water meter.

Pay attention to moisture-proof, moisture-proof, and strictly prohibit water droplets from penetrating into the water meter controller, damaging the control system, and affecting the normal use of users.

For accurate metering, the faucet should be higher than the water meter. And the installation of at least 10 times the length of the pipe diameter, at least 5 times the length of the pipe diameter of the straight pipe section, the water meter should not be directly connected with the pipe, the water meter and the pipe should be connected by the pipe, sealing washer, connecting nut, disassembly and assembly, do not use force to pull hard, so as not to damage the case.

When installing a water meter with water-saving function, a special pipe joint must be used at the water inlet to reduce the rotation of the water meter caused by water pressure fluctuations.

The number displayed by the water meter is the total amount of water used by the user.

1. Digital water meter.

The first 4 digits of this meter are black, the 5th digit is red, and there are only 3 red hands.

The " next to the red pointer means "the number pointed by the pointer ton"; The " next to the red pointer means "the number pointed by the pointer ton"; Therefore, the power of the above table should be tons.

Second, pointer water meter.

Let's look at the kilotonium first, the kilotonage pointer is between 0 and 1, so the kilotony reads 0.

Looking at the 100 tonnage again, the 100 tonnage pointer is between 7 and 8, so the 100 tonnage reads 7.

Looking at the ten-tonnage again, the ten-tonnage pointer is between 6 and 7, so the ten-tonnage reads 6.

Finally, look at the tonnage, the tonnage pointer is between 8 and 9, so the tonnage reads 8.

After the above steps, we finally came up with the number of water meters in the above figure as 768 tons.

Water meter readings frequently asked questions

1. The water meter reading and water consumption are inconsistent.

First close the gate valve in front and back of the water meter tightly (if there is an anti-theft valve, please ask the water supply company to assist in closing), observe whether the water meter is moving, generally speaking, it will definitely not go back.

First open the front valve of the water meter (refers to the valve of the water meter inlet), observe whether the water meter is moving, if walking, it is obvious that the connection between the water meter and the rear valve is leaking, but this situation can be seen, so it is normal not to move, if you walk, it is that the water meter is broken. If the water meter no longer reads after closing the front and rear gate valves, it means that there is no problem with the water meter, otherwise, the water meter is broken.

In the case that there is no problem with the water meter, it is recommended to check the plumbing in your home thoroughly, if the meter reading and the water consumption are not consistent, it is most likely that the solar water heater pipe or toilet water supply pipe is leaking.

2. How to clear the reading of the water meter.

A normal water meter cannot be cleared unless the maximum value is used, and then it is cleared after repeated use. The smart water meter has a zero card, and it will be cleared when you swipe it.

The general water meter refers to a meter that calculates water consumption, how to check how many tons of water is used through the water meter, you can refer to the following experience of viewing the water meter to display water consumption.

Tools Raw materials: one water meter.

1. The general water meter will have a protective cover on the dial, and when you want to check the water consumption on the water meter, open this cover first.

2. Then on the water meter, there is a rectangular display window, which shows the number on it, which is the current total water consumption, and the back is marked with m3, which means that the unit is cubic; Subtract the previous total from the current total, and that's the water consumption for the recent period.

3. Although the appearance of some water meters is different, there is generally a small window showing the number, and if it is marked with M3 at the back, it 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 addition, in the water meter, there is a circular gear-like thing, this is generally the water flow indicator wheel, when the water is released, the faster the indicator wheel will rotate, when all the faucets in the room are turned off, the indicator wheel is still rotating for a long time, that means there may be water leakage.

5. In the water meter, there are some small pointers, which may be judged by the numbers marked above, as shown in the figure below, arrow 1 refers to nearly tons, and arrow 2 refers to nearly tons.

6. There are two pointers at the back, as shown in the figure below, arrow 1 is, arrow 2 refers to, these are mainly used to read the water consumption more accurately, generally look at the water meter, mainly to look at the numbers in the small window at the top.

1. How to read the number of the water meter.

1. The types of water meters are different, and the methods of water meter viewing are also different. If it is an old-fashioned water meter, it has 8 digit circles on it, and these 8 digit circles represent the position of the digits, such as single digits, ten digits, hundred digits, and so on. As long as the numbers on these circles are read out separately, the total water consumption is formed, and then the numbers read before are subtracted to get the flow of water for this period of time.

2. Now basically the water meter that displays the number will be used, and the digital water meter is also different, one is that there are 5 numbers on it, and these 5 numbers are black, so this is a number to indicate that this is an integer, indicating how many tons of water used this month. If you want to be accurate to the decimal point, you need to read the numbers in the circles below, moving them back by one place from top to bottom.

3. There is also a water meter that displays numbers, which is also 5 digits, but its first 4 digits are black numbers, and the last digit is red numbers, which is different from the previous table. The red number indicates that there is a decimal point in front of it to indicate a few tenths of a ton, while the black number in front of it is an integer that indicates the tonnage of water used. If you want a more precise value, you can also continue to look down at the numbers in the circles, and read the numbers in the circles from top to bottom, adding one decimal place to each place.

The figures in these meters are all indicative of the total water consumption, and if you want to get the water consumption for a certain period of time, you still have to subtract the previous readings from the current reading to get the water consumption for this period.

2. Precautions for the use of water meters.

1. When installing the water meter, you should consider the diameter of the water pipe in your home and the water flow rate at home, and choose the water meter of the appropriate range for installation. It shouldn't be too big, and it shouldn't be too small. Too large a reading will not be so accurate, too little will exceed the range, put pressure on the water meter, and the value will not be accurate.

2. The water meter should be installed at the position of the water valve as much as possible, so that the water consumption at home can be more accurately measured.

3. The water meter should be installed in a location that is easy to view, but it should also be noted that it should not be placed in a location that is easily polluted, or in a location that is exposed to the sun.

4. The scale of the dial of the water meter should be upward, so that it is easier to read the value on the water meter. The direction of its flow should be consistent with the direction of the arrow on the water meter.

If it is an old-fashioned water meter, read out the values in each small circle in turn, and then combine them. If it is a water meter with 5 digits and black numbers, read the whole number, and more accurately read the numbers in the circle below. If it is a water meter with 4 black numbers and 1 red number, its red number is to indicate a few tenths of a ton.

<><6. Then this water meter is now using 0+ tons of water.

1. The common combination of the word wheel and the pointer displays the reading, and the black word wheel reads the reading. 2. Reading the display mode of pure pointer; Black pointer reading. 3. The last digit or digits in the word wheel are red, and we can ignore these digits.

Read the black word wheel readings: 100,000 digits, 10,000 digits, 1000 digits, 100 digits, single digits.

When the water is not used, when you see that the pointer of the water meter, such as the red pointer, is still rotating and moving, it indicates that the water equipment is leaking and should be repaired in time. The installation of the water meter must be kept flat in the horizontal direction, and should avoid fire, scalding, flooding and violent vibration, so as to prolong the service life of the water meter and ensure the accuracy of measurement. Remind users to pay attention to timely recharge when using smart water meters to ensure the normal operation of water meters.

How to choose a household water meter: 1. Look at the specifications to buy a household water meter, you need to pay attention to the size of the specification, according to the pipe diameter to choose, if the pipe diameter is 200mm, you can choose a 150mm water meter, to choose a water meter smaller than the nominal diameter of the pipeline. 2. Look at the indication typeThe dial of the general water meter is of the word wheel type, which is convenient for reading and reading.

3. Look at the convenience of installation and maintenance: the installation of large-diameter water meters needs to take into account the maintenance problems, which are more troublesome in maintenance, because the water can not be stopped. 4. Look at the adaptability of water quality

Because there are some differences in the tap water from different water plants, and the water quality will be affected due to some reasons in the transportation process, there is no cleanliness when leaving the factory, and it will be contaminated with some impurities, so it is necessary to choose a suitable water meter.
