How to open the water meter cover?

Question 1: How to screw the cover of the old reading meter? In case of disassembly, first remove the nylon rope or iron wire with lead seal. Generally, a special tool, hook wrench or pipe wrench is used to unscrew it counterclockwise, but it can also be opened by a simple method, that is, a hexagon screw with a thickness of 10mm and a length of about 10cm is used to impact the protruding point of the meter cover counterclockwise with a hammer. Now let's find a professional to do electronics!

Question 2: How to open the glass cover of the water meter? Cut off the lead seal on the water meter and open the copper seal with a pipe wrench. Replace it with a new one (don't forget the sealing ring) and reinstall the sealing cover with a pipe wrench.

An instrument for measuring water flow. Most of them are cumulative flow measurement of water. Generally divided into two types: volumetric water meter and speed water meter. The former has higher precision than the latter, but it requires high water quality and is easy to block when water contains impurities. An instrument for recording the water consumption of tap water is installed on the water pipe. When the user discharges water, the pointer or character wheel on the water meter rotates to indicate the amount of water passing through.

Installation method of water meter:

1, the diameter of the water meter should be determined according to the diameter of the installation pipeline, and the installation position should avoid exposure to sunlight, immersion, freezing and pollution, which is convenient for disassembly and swiping.

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

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

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

5. If the water meter is installed at the 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 flowing back and damaging the internal parts of the water meter.

Question 3: How to turn on the old water meter? This is a mechanical water meter. The following are the methods of meter reading: 1. Identify the dial. At present, mechanical water meters used at home generally have eight dials. The four red indicators on the right: ×0. 1, × 0.0 1 ... are all less than 1 m3 because of tap water. Generally, these dials have no practical guiding significance and do not need to be seen. The four black hands on the left indicate that the dial × 1 and × 10 ... are the basis of tap water metering and charging, LZ should learn to understand. Second, recognize the pointer. Four black hands indicate that the dial is counterclockwise from top to bottom, namely one needle (× 1), ten needles (× 10), hundreds of needles (× 100) and thousands of needles (× 1000). The pointer of × 10 turns once, and the pointer of × 100 goes one word; The pointer of × 100 turns once, and the pointer of × 1000 goes one word. Third, the essentials of reading. When reading the water meter, you should read it from the high pointer to the low pointer in turn, that is, read it clockwise from bottom to top based on the indicated value of the pointer × 1000. It is important to pay special attention to: if the position of thousands, hundreds and tens pointers is between two numbers, we should pay attention to the association between the upper and lower adjacent pointers. Generally speaking, you should take a smaller one. If the pointer is 0-, the LZ water meter can be read according to the meter reading method.

Generally, you only look at the black table number, which is the whole tonnage, and the red table number is the tonnage after the decimal point. X 1000 stands for thousands. The number of the black table x 1000 is 0, so this is not read. X 100 represents the hundredth digit of a number. The number of black table x 100 is 6, so the percentile of this study is 6. X 1 represents the ten digits of a number. The number of black table x 10 is 9, so the decimal number of this reading is 9. X 1 a single digit representing a number. The number on the black watch is 9, so the single digit of this reading is 9. Since the reading is 0 in one thousand (not read), 6 in one hundred, 9 in ten and 9 in one, the water meter reading is 699, and * * * used 699 tons of water.

Question 4: How to open the water meter cover? If you need to open the plastic cover to read, just open it 90.

Question 5: What should I do if the water meter is unclear? How to open the water meter cover? My watch was changed by the water meter checker 100 yuan.

Question 6: Is there any special tool to open the copper cover on the water meter? 10 minute water meter needs to be opened with a tool (special wrench), and the meter should be sealed with lead. You can find the property management department or the maintenance department of the water company for maintenance. Individuals are not allowed to disassemble and clean without permission, so as not to be suspected of stealing water.

Question 7: How to open the copper cover under the water meter cover? The water meter you use needs special tools to open it, and it must be sealed with lead. You can find the property management department or the maintenance department of the water company to repair it. Individuals are not allowed to disassemble and clean without permission, so as not to be suspected of stealing water.

Question 8: How to open the glass cover of the smart water meter, cut the lead seal on the water meter and open the copper seal with a pipe wrench? Replace it with a new one (don't forget the sealing ring) and reinstall the sealing cover with a pipe wrench. An instrument for measuring water flow.
