What s going on with the water meter?

This is when the water meter has a pipe pressure fluctuation or water hammer.

First of all, from the non-negative pressure frequency conversion water supply system, when the system stops water, when the water comes again, when the water stops, the user still has the phenomenon of using water, after the water in the pipeline flows out, there will be air into the pipeline, when the water supply is supplied again, the air in the pipeline is not excluded, then the pipeline is formed, the phenomenon of gas adding water, the density of the water is not enough, but the pressure is enough, when you don't use water, other people are still using water, then the pressure in the pipeline is reduced, and your water meter will (invert) slower, When other people don't use water, the water pressure increases, the water fills the air and increases the density of the water, and then the water meter will be slower, and if it is, the water meter will move repeatedly, and this is what you see.

Solution:1Add a check valve in front of the water meter.

Or call ** to find a local water supply company (usually a water company) and ask for a water meter.

2.Turn off all the devices that can make a sound in the bathroom, and if you put your ears close to the water tank, you will hear the sound of zit, and then you will conclude that the water supply valve is aging and replace it as soon as possible.

3.Some users have installed Rebao or wall-hung boilers.

Due to the difference in hot and cold water pressure, it can also cause the phenomenon of "water hammer". For now, the solution is to install a check valve.

First judge whether there is a water leak, if it is ruled out that it is a water leak at home, then consider the problem of water meter rotation.

The reason for the rotation of the water meter is that the water flows through the water meter, driving the impeller of the water meter, but many times the pressure before and after the water meter is unstable, resulting in the water meter turning forward and then reversing. The solution is to add a check valve in front of the water meter.

The main reason comes from the secondary water supply system, which can occur in several cases:

1. From the non-negative pressure frequency conversion water supply system, when the system stops water, when the water comes again, when the water stops, the user still has the phenomenon of using water, after the water in the pipeline flows out, there will be air entering the pipeline, when the water supply is supplied again, the air in the pipeline is not excluded, then the pipeline is formed, the phenomenon of gas and water, the density of the water is not enough, but the pressure is enough, when you don't use water, other people are still using water, then the pressure in the pipeline is reduced, your water meter will be (reversed) relatively slow, when others don't use water, The water pressure will increase, the water will fill the air part to increase the density of the water, and then the water meter will be slower, if the water meter is repeated, this is what you see, the reason why the water meter rotates as usual, and after a period of use, the air in the pipe is discharged, and this phenomenon disappears.

2. High-rise buildings and tap water pipelines according to the height and natural pressure of the water to ensure that the tap water pressure does not exceed the specified value ( Install (pressure reducing equipment, pressure reducing valve) in the corresponding position (pressure reducing equipment, pressure reducing valve) When the pressure valve fails, the flow rate will be reduced, and at the peak of use, the flow rate will not be reached, and then there will be air entering the pipeline, and there will also be the water meter mentioned above (strange rotation), this phenomenon will always exist, and the water pressure at home will be reduced accordingly, and it will be felt when in use. If this phenomenon persists for a long time, it is necessary to find a property to replace or repair the equipment.

3. Now the water meter is manufactured precisely, the water pressure rarely changes, the water meter will rotate, if the water pressure at home is not small, there is no change, find the water company, replace the water meter, (the water meter is a one-time configuration, the property rights belong to the water company, it is free to replace).

4. If the water meter rotates in only one direction, it is your bathroom and toilet tank, and the water valve is not closed strictly.

The water meter got into the air.

When a water meter is newly installed or moved outward, the water in the user's pipe is emptied, and the air is defeit"Take advantage of the situation"；When the water flow is restored, the water flow presses the air in the pipe to the blind ends of the indoor pipe, forming it"Compressed air"until the air pressure equalizes with the water pressure. There is an interface between gas and water, and the pressure difference between the two sides of the interface is zero.

When the water pressure changes, a certain pressure difference is formed between the two sides of the interface, and the balance of air and water is destroyed. To compensate for this pressure difference in order to achieve a new equilibrium, the pressure of the air must be changed accordingly, which causes the volume of air to expand or contract, thus prompting the pipe to this"Communicators"The tap water within produces a flow, thus,"The water meter is idling"The phenomenon arises.

Precautions for the use of water meters.

The installation location of the water meter should be convenient for disassembly and meter reading, and should prevent pollution from exposure and freezing. At the same time, the oil valve should be installed before the installation of the water meter, so that the water can be disassembled and disassembled.

When installing, the hemp wire, ore and other debris of the pipeline should be removed to prevent the water filter from being blocked, otherwise the word value error will increase, and affect the water supply, the liquid in the pipeline is corrosive or high-temperature liquid, which will cause the deformation of the movement, and the use of this water meter should be avoided.

There is air in the tubing. For example, if a water meter has just been replaced, there is a small amount of air in the meter or pipeline, and the air is slowly compressed by the water, which is reflected on the water meter, and the water meter will rotate slowly. (This phenomenon will disappear after a day or two).

There is a drip in the tubing.

The water meter stops and goes, and it may be based on the water consumption at home. If you have been using water and still stop and go, then there is a problem and you can replace it with a new water meter.

What's going on with the water meter? It is very likely that the counter in the middle of the meter is faulty, which can cause this reason.

When the water is used normally or when it is not in use, the water meter stops and goes, indicating that the water meter is broken. The water meter walks when it uses water, and does not go when it does not use water, which means that the water meter is normal. If the water meter is broken, report to the water plant for review and maintenance.

It's normal. Leave when you use water, stop when you don't.

It is to use water occasionally, and then it is not used again. So it goes and stops.

Clever answer: When there is water at home, the small impeller of the mechanical water meter rotates, and stops rotating when not in use.

What is the matter with the water meter when it goes and stops, the water meter will go when the water is used, and the water meter will stop when it is not in use. Normal.

There is a quality problem and it needs to be repaired.

The phenomenon that the water meter will slowly rotate and stop for a while may have the following reasons:

There is an internal leak in the pipes or water appliances behind the meter, causing the water flow to constantly push the meter around. The solution is to check and fix the leak.

There is air in the pipes, which causes the water pressure to be unstable, forming a water flow and an air flow that alternately pushes the water meter to turn. The solution is to exhaust the air in the pipe, which can be achieved by closing the valve in front of the meter, opening all the faucets behind the meter, draining the remaining water, and then opening the valve to discharge the water for a period of time.

There is a water hammer phenomenon in the pipeline, that is, due to the sudden closure or opening of the valve burial hall, the water pressure changes sharply, causing the water flow impact and **3. The solution is to find the cause of water hammer and eliminate it.

Pressure fluctuations caused by secondary water supply facilities lead to unstable water flow in the network. The solution is to adjust the setting and control of the secondary water supply facilities.

The above are some possible causes and solutions to bending and concealment, and the specific situation should be judged according to the actual situation of your pipeline and water equipment.

There are several possible reasons why the water meter is unstable:

1.Pipe leakage: When the pipe leaks, the water flow rate will decrease, resulting in a slower or unstable rotation speed of the water meter.

2.Unstable water pressure: Unstable water pressure may also lead to unstable grip speed of the water meter. When the water pressure decreases, the water meter speed decreases. Conversely, when the water pressure increases, the speed of the water meter will increase accordingly.

3.Water meter failure: The parts inside the water meter may have problems such as wear and age, which may also lead to unstable water meter speed.

4.Water quality problems: If there is a problem with water quality, such as a large amount of sediment or impurities in the water, it can also cause the water meter to be unstable.

If your meter speed is unstable, it is recommended that you first check the pipes for leaks to ensure that the water source is unobstructed and undisturbed. If none of the above causes are present, the meter may need to be inspected and repaired. It is best to contact the water department or a professional water meter repairer in the local area for inspection and repair.

It may be that there is a leak in a pipe or toilet, or a leak in the pipe behind the meter that is difficult to detect, such as a pipe embedded in a wall or buried in the ground.

It may be that there may be air trapped in the ducts. When the water pressure rises, the air bag is compressed, and the air bag is stretched when the water pressure decreases, which pushes the water back and forth, causing the water meter to rotate back and forth occasionally.

Please note that if the water chain grip is constantly turning, it may result in a waste of water and may also affect household water use. Therefore, you should contact a professional maintenance personnel in time to check and repair the water pipes to avoid waste of water resources and inconvenience to household water.

There are two scenarios:One is when someone steals water or some invisible water leak, and the other is if the floor is highThe water meter is installed at the bottom of the building, and the water meter inlet is not a check valve, if the water stop is too much, the water meter will go without water.

According to the measurement grade: according to the old standard, it can be divided into A-level table, B-level table, C-level table, and D-level table.

The metering grade reflects the meter's operating flow range, especially the metering performance at small flows. According to the order from low to high, it is generally divided into A-level table, B-level table, C-level table, and D-level table, and its measurement performance meets the corresponding requirements of the measurement grade A, B, C, and D specified in the national standard.

With the release of the new version of the standard, the classification of metering grades has become quite complex, mainly based on various parameters such as flow value and volume ratio. To put it simply, the larger the measuring range, the higher the metrology level.

According to the measuring principle:

It is divided into speed water meter and volumetric water meter.

1) Speed water meter: A water meter installed in a closed pipeline, composed of a moving element, and directly obtained the power speed by the water flow velocity. Typical speed water meters include rotor water meters and spiral wing water meters.

There are single-beam water meters and multi-beam water meters in the rotor water meter.

2) Volumetric water meter: A water meter installed in a pipeline that consists of a number of chambers of known volume that are filled and discharged with fluids one by one and a mechanism driven by fluids, or simply a quantitative discharge water meter.

There are two scenarios, one is when someone steals your water or some unseen water leak.

The other is that if you have a high floor and the water meter is installed at the bottom of the building, the water meter inlet is not a check valve, if the water stop is too much, the water meter will go without water.

That is to say, when the water enters the water meter and then leads to the upper floor, the meter has been counted, and the water returns after the water stops and the original number remains the same, if the number of round trips is too much, you have not used the water at home, and the number on the water meter will continue to increase.

Why does the water meter turn when no one uses water, the water company employee told the truth.

What happens when the water meter stops and goes when the water is not being used? When the water is not used, but the water meter turns a few times after a while, and then stops again, and repeatedly. What's going on.

What happens when the water meter stops and goes when the water is not being used? When the water is not used, but the water meter turns a few times after a while, and then stops to take the greeting, over and over again. What is the situation 1, non-uniform speed walking:

If the pointer stops and goes, walk backwards, quickly and slowly, and the preliminary judgment is that there may be air in the pipe. 2. Move at a constant speed: If the water meter rotates at a constant speed, there may be a leakage inside.
