A gas meter is fairly reliable equipment: its service life is calculated in tens of years. The operation of each metering device is checked at the factory immediately after production, which is why the defect rate is so low. But, unfortunately, gas meters are also prone to malfunctions.
In this article, we will analyze in detail why the gas meter makes noise or creaks, we will answer whether it needs to be repaired or changed, and also tell you where to go.
IMPORTANT!Any work with gas equipment should be carried out only by employees of specialized organizations that have received permits and certificates. Self-intervention is strictly prohibited!
Natural noise during meter operation
Do not get upset ahead of time: some types of gas meters really make a lot of noise during operation, for example, membrane or rotary ones.
There are two chambers inside the diaphragm meters, the gas alternately stretches each of them, activating a rod connected to a pendulum in the dial.
Rotary metering devices consist of rotating rotors that drive gas flowing through the device. Therefore, it is not surprising that such mechanical counters make a lot of sounds during operation.
In addition, the noise during operation can be influenced by weather phenomena: squeaking occurs when exposed to low temperatures, moisture, or direct sunlight on the meter. Such problems are most likely if the gas meter is cheap and assembled from low-quality materials.
What to do?
We offer 5 solutions to the problem:
- Soundproof cabinet. Special lockers for counters made of metal or plastic are on sale. They are specially designed to reduce operating noise, protect the device from the natural environment, taking into account the rules and requirements for safety. In addition, you can make such a cabinet yourself: the main thing is not to forget to design ventilation. In the best case, pay a fine, in the worst case, an explosion will occur.
- Insulate and insulate gas pipes. The advice is relevant if the device is installed outdoors. This will not only reduce noise but also reduce gas consumption.
- Soundproofing a kitchen or room. If you are planning a renovation, then think about additional soundproofing of the walls.
- Move the gas meter. In this case, you will definitely need to contact the gas distribution company, which must give permission for redevelopment in order for the counter to move their kitchens to the corridor or to the street. We warn you right away that this procedure takes several months.
- Replace counter. Sometimes it is easier to replace a flow meter with a new and different type, for example, an ultrasonic one. In this case, you will also receive a new warranty for the device.
Debris inside the appliance
If the meter is installed outdoors, dirt, leaves, or various insects can get on the case. During operation, the meter vibrates, and foreign particles can get inside the device and cause noise and squeaks during operation.
What to do?
It is necessary to call the gas service personnel who will remove the device, clean it and install it back.
The tightness of the case is broken
It is most dangerous if the sealing of the device case is broken, and gas escapes through cracks with a whistle. In this case, the meter incorrectly records the amount of gas consumed, and can also cause a tragedy: from suffocation to an explosion. In the vast majority of accidents with equipment leakage faults.
What to do?
If a gas leak is confirmed, the meter must be urgently replaced. Do not leave the problem to chance and forget about repairs – your safety and the health of your loved ones are above all.
Normal wear and tear
Although the service life of the meter is more than 20 years, some components wear out faster during operation. Already after the first verification, the rotors of the device may begin to jam, and the wires may oxidize. It is quite simple to detect this: such malfunctions stop almost immediately after turning off the gas appliances.
What to do?
Most likely, the service life of the meter has come to an end, the components cannot be replaced, so we can only recommend replacing the meter with a new one.
Soundproofing with a soundproof cabinet
To hide the noise in the gas meter, you can make a soundproofed plasterboard box with a built-in hatch to access the device. The box must be made with a foam seal for each of the walls.
By design, the box itself is a profile frame, sheathed on both sides with plasterboard and a foam pad between them. It is important that the walls of the box should never touch the device’s body. This design absorbs high noise levels.
It is important to take into account that such an add-on can be met with the disapproval of the gas inspectors, so do it at your own peril and risk.
The gas meter can squeak for various reasons, including gas leakage, so it is important to follow safety precautions. Limit your physical examination and keep your interactions with the device to a minimum. For a more thorough examination, invite a specialist.
In case you suspect a gas leak, immediately report it to the emergency service of the gas network. If no problem is found and the meter is working properly, you can replace it with another model or install a soundproof cabinet.
Alternative options for getting rid of noise
If external cleaning, an inspection of the gasman, and repairs did not bring results, and the cabinet cannot be installed, you will have to choose one of the alternatives.
If the device is buzzing, there are still 4 ways out of the situation:
- Move the flow meter.
- Reduce noise by insulating the gas pipes through which it travels.
- Arrange to soundproof the kitchen or other room.
- Buy another meter, which is more cost-effective than repairs and reinstallations.
A squeaky counter will not cause discomfort if you move it outside. The technical feasibility depends on the drawing of the pipeline. You will need to contact the gas distribution company. The level of complexity of the operation depends on whether the organization agrees to work or not.
A gas meter on the street also requires additional protection, a visor or the same cabinet, as well as insulation of gas pipes. The likelihood of a meter breakdown on the street will increase. The idea has a modest economic benefit and only if the gas meter will last some more time. You will need a thermocorrector and, in addition, the recorded indicators will grow.
Not all meters are suitable for outdoor installation, and sometimes it is better to buy a new one right away because you have to spend money on protective and metrological equipment
The sound from the meter also spreads through the pipes. The problem will become less noticeable after they are insulated. As a result, gas consumption will also decrease. In practice, a blanket is often used, and close to the counter. Ideally, reliable 3-layer insulation is used.
The base is formed from 2 layers, including a primer and a primer as an adhesive. Initial coatings prevent the polymer from peeling off the steel pipe. Extruded plastics are used directly as insulation. These measures also reduce the risk of moisture and temperature fluctuations in the pipes, which is good for the meter.
Sound can be isolated from spreading throughout the apartment, while simultaneously softening its strength in the kitchen or technical room. Soundproof foam rubber or polyurethane foam is attached to the walls, with installation on the frame. Sound-absorbing panels are mounted on top. The decoration is then made out of plaster. Noise insulation for 1 wall with a counter is not enough. To enhance the effect, it is better to process the opposite one as well.
Without adherence to technology, the end result will be weak. The first layer of sound insulation is necessarily made with a blown structure, the second is heavy and dense. Do not leave gaps between soundproofing panels, but also make a hard joint with a wall, floor, or ceiling.
