Water meter: a device suitable for installation

In today's world, the installation of water measuring equipment is not a rare phenomenon. Many families use counters to reduce the financial cost that goes to pay utilities. To select the counter in the water, you need to understand the principle of operation of such a device, and should explore the main types of water meters and their parameters.

Water meter: does it make sense to install a water meter

Communal organizations establish tariffs in such a way that the probability of losing their own benefit has been reduced to a minimum. There are many situations where the user is paying for the service, the quality of the provision of which is not the best. In this case, will help solve the problem of installation of special test equipment. Meters can be of different types, so some problems may arise in the selection of such a device.

It is impossible to deduce the exact figure, which saves the installation of this equipment. This is due to the fact that the level of savings depends on many factors such as the location of the apartment, the layout, the number of registered and living upon the tenants. However, in most cases, the meter installation helps to save the family budget.

Today, the state documentation contains all the necessary information about the rules of water per person (without a meter). These figures, as noted by many consumers, too high. Installation of water measuring device allows the user to get rid of unjustified overpayments.

Note!Installation of water measuring equipment allows to solve another auxiliary problem - to reduce the cost of wastewater. Rates for this service is usually also high.

For owners of private homes water connection meter is especially advantageous. This is due to the fact that the norms of water consumption in this case is much higher, since it is added to the costs of irrigation, as well as the maintenance of the car (if there is a garage on the site).

How to watch the testimony water meters? Observation data can be produced in a conventional manner or remotely. The second option allows for the use of special sensors, transmitting data on the liquid flow rate on computer. There are special programs to simplify the calculation of the cost of services, which is very convenient.

Water meter: design features flowmeters

All modern water metering device conditionally divided into two blocks, independent from each other. The main part of the meter - housing. metal most commonly used for manufacturing the casing, resistant to corrosion. The most common one is bronze. Technical characteristics of the material under ideal operating conditions counters.

The flowmeter body has an external thread, which is necessary for carrying out tapping device in communication. The thread located on the two nozzles that are fixed to the pipes by means of special connecting elements. The materials used for the manufacture of the meter must be of high quality and comply with government regulations. The water meter comprises an impeller, which is part of the housing.

The second flowmeter unit (upper) represented countable drum. From the name it becomes clear that this element is necessary for calculating an accurate flow rate in the system. The unit has a dial with an arrow. When the arrow overcomes one lap, then the drum there is the number 1, which corresponds to the number of liters of water consumed.

Both units have one thing in common: they are completely sealed. Payment of water on the counter is made in accordance with the amount of consumed media. On the drum displays all the necessary information, which can be removed without difficulty.

Helpful information!Each water-metering device necessarily being checked for accuracy. For this purpose, a special prolivochny stand. After each counter is run 200 liters of water, after which the accuracy of the data is checked, the registered device. If during the test device was deemed to be too accurate, then it is sent to the migration.

The operating principle of the account of water meter: how is the data logging

Immediately it is worth noting that not every product is suitable for use in the home. Some water meters made exclusively for installation in production plants. Operating affiliation water metering products - one of its most important characteristics.

Which is better for water meters inside apartment application? For use in the home often takes a simple device. Most suitable are one tachometric meters. They are characterized by a democratic value, ease of performance and are resistant to the conditions prevailing in the domestic water supply systems.

The principle of operation is quite simple tachometer devices. Data read is done by rotating the impeller or impellers. Both of these elements results in movement of the natural flow of the media in the system. Needless reader device may be mechanical or function due to electronics.

Each full turn of the shaft connected to the impeller, corresponds to a certain volume of water. Since most working devices mounted on the cold-water network, and hot water meters. Price for water consumption can be reduced by using multi-rate devices.

Tachometer models feature a small error in data records. It should say that today you can buy a combined flow model. They have a more complex structure and contain special valves. With these switches medium flows.

In addition to the tachometer, ultrasonic considered fairly common model. Their principle of operation is based on the measurement of ultrasound waves passing through a media stream. Comparison of the data obtained by this method to determine the volume of water consumed per user per month.

Types of water meters: mechanical and electromagnetic devices

All water metering devices are differentiated on the mechanical and electromagnetic. Classification in this case is made by taking into account the mechanism of the device, as well as on the basis of what kind of energy is used to operate the device.

Mechanical models do not have electronic components and operate due to vehicle movement in the pipeline. Water in the communication passes through the structural elements of the device, thereby causing them to spin. The amount of water meter impeller turns recorded on a special display.

Water meter counters of this type have many advantages. The main advantage of these models is safe to call them low cost. They are autonomous, and are distinguished by reliability and efficiency. The service life of such devices can be up to 10-12 years.

Mechanical devices used to register flow indications may be single-jet or two-. In the second case the water inside the water measuring device is divided into two streams. Such a measure can increase the accuracy of the readings. Water accounting on the counter made 1 time per month.

For mechanical models, they have other positive qualities. For example, most devices of this type have high maintainability. Therefore, when the output of such devices out of action is not difficult to call a specialist who will fix it.

Helpful information!Mechanical devices have a compact size, which greatly simplifies the choice of location for their installation.

Like any other device, a mechanical water meter has some negative aspects. The measurement accuracy of such a device is primarily dependent on the quality of the media in the pipeline. Thus, if water is present in the plurality of foreign substances, then the efficiency will decrease the water meter. Also worth noting is that these products have increased sensitivity to electromagnetic fields.

Counters of cold-water and hot-water electromagnetic type: features

Electromagnetic devices, as opposed to mechanical, produce the most accurate reading of water consumption, that is, the installation of this equipment saving rate reaches its maximum. Such instruments are classified as volatile.

Electromagnetic water metering devices also have another advantage: during verification of the counter no need for its complete removal. Housing mechanical equipment is completely dismantled in such a situation. The accuracy of electromagnetic products depends on two factors:

• medium purity;
• water temperature.

Water meter price of this type is its principal disadvantage. Among other things, to purchase such a device more difficult as the electromagnetic devices are not always available in some stores. In order to carry out the installation of such a device, it is necessary to apply to a specialized firm, which has a license to carry out installation work.

How much does a water meter of this type? Price devices relating to electromagnetic band higher than the cost of mechanical counterparts. It ranges from 1000 to 3000 rubles. These flowmeters have resistance to the effects of electromagnetic fields, which is also an advantage and effect to increase data accuracy.

Most of these water metering devices are categorized as multi-tariff. This allows for the appropriate setting by dividing the net payment by a few points (depending on the water temperature). Photos water meters of this type help to visually assess their advantages and disadvantages.

Electromagnetic flow meters are easy to install. They have the ability to install both in horizontal and in a vertical plane. it is recommended to pay attention to the quality of the housing, as is often encountered in selling shoddy forgery, the service life of which is much lower when choosing such a device.

Varieties counters: the ultrasonic and eddy devices

In addition to mechanical and electromagnetic, Sales found two other types of flowmeters. The first of them - ultrasound. They also relate to the volatile categories, so their operation requires electrical energy.

Work and data registration in this case is made by ultrasound. Moving in the direction of movement of the carrier, as well as against him, ultrasound allows to obtain the necessary data for comparison. Water meter of this type has one major drawback - high cost.

Note!On the positive side it is necessary to mention the long-term service life of ultrasonic devices (15 years).

In turn, the eddy models determine the amount of water passing through them, with a special electronic device. The design of such models implies the presence of a special barrier that forms a swirling water. The rate of such track is a key indicator. The electronic device reads this parameter and, based on the data obtained defines the carrier flow.

Counters for cold water, as well as devices used in domestic hot water network effectively operate only when the water has no impurities. The operational life of the vortex device is approximately 8 years.

Thus, under conditions that correspond to the operation of domestic pipe is relatively good work only mechanical models - tachometer. Therefore, it is a mechanical device is a leader in sales.

Meters for hot and cold water: the classification of the temperature and operating principle

All water metering devices are divided into two large groups. The first group includes models which are used for fixing the data flow of cold water. Second set DHW communication. Before you purchase a particular variety is recommended to get acquainted with the permissible ambient temperature for the counters.

Water meter cold water meters are operated at a maximum temperature of +30 ° C. Increase in this parameter will lead to a malfunction of the device. Water metering device for a hot water network is allowed to use in the event that the support temperature does not exceed +130 ° C.

Price counters for hot water is higher than the cost of their cold analogues. Additionally, such devices have a smaller interval between verifications. The high cost of metering devices for WAN networks is because they are made of more expensive materials, which are resistant to high temperatures.

Note!Today, you can buy and universal models that can function as networks of hot water and cold communications.

How to distinguish water from the cold water meter devices that cut into the hot water supply? To avoid any problems with the purchase of a unit, they are usually painted in different colors. counter housing intended for communication HVS has a blue color. Water meters on hot water produced red. Universal devices also have a unique color - orange.

All devices used for securing data in water supply networks, differentiate one more feature - on the principle of work. Depending on this factor are the following devices:

• single-jet;
• multijet.

In the first case, the device is designed so that the water travels through it a stream. During operation of the meter it hits the impeller, which adversely affects the accuracy of the recorded data. These models are available for use inside apartment. Counters for hot water and cold-water networks of this type is recommended to buy only in secure locations. To save on the purchase of test equipment is also not worth it.

Multijet model mounted on the pipe, the diameter of which exceeds 40 mm. They are characterized by a high measuring accuracy, but not used in the home.

"Wet" and "dry" counters hot and cold water: the difference

Classification of all the water meters in the "wet" and "dry" device made in depending on their frame. The first of these are installed directly in the pipeline construction. During operation of such a device in contact with water, which adversely affects their condition.

Channels of even the best counter to this type of water quickly clogged if you do not take the necessary protective measures. Solve the problem of rapid wear of "wet" devices allows to install a special filter element. It retains large foreign particles, reducing the negative impact on the counter. It is important to remember that the filter is mounted in front of a water meter.

"Dry" model is not in direct contact with the carrier in the pipeline, so the service life of such devices more. From the flow of water protects them a special baffle, which is non-magnetic.

These counters record a more accurate reading, it is their absolute advantage. Models that belong to the group of "wet" are much cheaper. counter price for cold water of the type most often does not exceed 1000 rubles. Experts strongly recommend to set before them strainers to prolong their service life.

It is worth considering the important characteristic of "wet" and "dry" devices, namely their sensitivity to magnetic fields. Most modern counters have a structure resistant to the effects of magnetic fields.

Using counters antimagnetic water can increase the data accuracy. This is due to the fact that such devices are resistant to electromagnetic fields. The apartments are newly installed water meters data in advance, which is very convenient.

Helpful information!Antimagnetic water meters related to the first group, have no sensitivity to external magnetic fields. In turn, the dry models can not boast the same.

Criteria for selection of the water meter: the price and specifications

When selecting a flowmeter need to learn the basic criteria that allow to get a safe and effective device. The modern market is full of a variety of models of flowmeters. Some of them are not suitable to the conditions of the domestic water supply structures.

In most cases, the water entering the apartment, contains relatively large amounts of harmful impurities. Foreign particles affect sliding parts counters, which leads to rapid wear of the devices. When selecting a flowmeter is recommended to pay attention to this point. Best water meters have a structure which eliminates such an arrangement of parts.

Another important point - the material from which made the enclosure. It must be resistant to corrosion, but also need it to be pretty strong to resist mechanical stress (shock). The most suitable embodiment for this purpose are alloys of different metals, such as bronze, brass and so on. N. On sale you can also find products made of stainless steel. However, they are not very common, because the material is more difficult to process.

Chinese companies producing similar products, using an aluminum silicon alloy. In contrast to the above-mentioned materials counters of this type do not provide long service life. However, they are well cope with the work in polluted water.

To answer the question of what counts on the water is better, you also need to pay attention to span the unit interval. This indicator measures the time interval between verifications, which are produced by municipal service specialists. The larger the interval, the more reliable is the device. Typically, the cold-water meters, he is 6 years old. The average interval between verifications for hot water meters - 4 years.

Note!For each device, regardless of the manufacturer, must be accompanied by a technical passport. Acquisition of the flow meter without this document is strictly prohibited, since its presence is a prerequisite for resolving the installation and putting into operation of the counter.

In addition, the device is important equipment. In a set with him must have all the necessary connection fittings, sleeves, as well as special seals made of rubber.

What counter to choose Advanced: water measuring devices

In addition to the basic characteristics, flow meters can have a variety of additional functions, depending on whether they belong to what type. Some of these options is an incredibly useful. Consider various modifications of such equipment.

Some models do not require constant removal of evidence. This process can be automated using special pads. Signal transmission is carried out via radio. It is worth noting that such specialized devices are not compatible with all types of water measuring devices. Most often, they are implemented in conjunction with a specific water meter.

Among the users of the popular, multi-tariff device. Determination of the water rate to the counter, in this case provides maximum economy. The device detects the water temperature and produces a distribution value depending on this parameter. Thus, the user pays for the actual temperature of the water in the pipes.

Multirate water metering devices are equipped with a compact CPU and small memory size. Most often, for the operation of such devices require battery service life which can reach seven years.

How much are the water meter: the purchase and installation price

All water metering devices are classified by their structure, which is determined on the basis of the principle of action. As of today, anyone can make a choice suitable for the specific operating conditions of the device.

The most common in the domestic market are mechanical devices such as a tachometer. They are highly suitable for applications in harsh environments in water supply systems. Tachometric meters are used to measure the volume of hot and cold water. Their price is very attractive. It ranges from 450 to 1500 rubles.

Note!Setting the counter allows you to save a considerable amount of money. water ratios on a person without a meter, usually 2 times higher than the actual flow rate.

The most expensive models of flowmeters are those that relate to the electromagnetic type. Their cost can be 15 thousand. rub. and higher. For home use the acquisition of such a counter is impractical. Most often, they are placed at different production sites.

Ultrasonic water measuring devices also are low cost. Measurement of fluid flow in this case occurs by means of ultrasonic waves, which compare the water streams flowing through the device. Price cold water meters of this type is an average of 11 thousand. rub. Cost models mounted on WAN networks can be up to 12-15 thousand. rub.

Another type of vortex flowmeters are device. Apply such instruments for the organization of control over the various technical processes. At home, for the use of instruments such is not recommended, but it is possible. The minimum value of the counters vortex type is 5 thousand. rub.

For use in the home is ideal tachometer devices having low price. What is better for the water meter apartment, extremely difficult to determine with absolute probability, but such models are suitable in most cases.

How much is the installation of water measuring device? The price of the installation of such devices depends on many factors. In the calculation of this figure takes into account individual characteristics of the pipeline. For example, a metal tie-in communication is more expensive because it is spent more time and effort. The final cost may differ depending on the region of residence. It ranges from 500 to 5000 rubles.

We should also mention the cost of periodic verifications. The cheapest will cost, this procedure if it will be carried out by experts representing the local management organization. Such a check would cost the customer about 500-1000 rubles. Services of private firms are more expensive and can reach 2-2.5 thousand. rub.

As to water seal the counter: recommendations

After the purchase and installation of water measuring devices made his oplombirovka. If the previous steps could be carried out with their hands, such work requires professional skills and knowledge. Setting the seal is produced by authorized personnel, who are managed by organizations performing services.

It should immediately be said that the utility may refuse to provide the user master. In such a situation it is necessary to apply to private organizations that for a certain value will set the seal on the water meter. For the work of the private professional need to pay more. The advantage of this method is the speed of oplombirovki.

Note!Private organization must be licensed, permitted to engage in such activities.

After the user is oplombirovki certificate certifying holding the corresponding operation. The master must specify all the necessary points in this document and sign.

How much is to seal water meter? The minimum cost of such services from private companies is 500 rubles. The best option - installation of two flow meters in the apartment. In this case, the company conducting oplombirovku can provide the client with a small discount.

What is required for oplombirovki water meter? This procedure is performed after tapping the device in tap design. In some cases, there is a need to re-install the seal. For example, it may be necessary after an accident in the water.

How to seal the water meter: Documentation

To carry out this procedure, you will need to prepare the necessary documents. User is obliged to provide product data corresponding to a specific device, and installation of an act that was prepared earlier.

It is important to remember that domestic legislation contains information that each user is required to carry out the installation of the filter. Only in this case, the counter can be put into operation.

How to seal the water meter? After preparing all the necessary documentation needed to apply to the managing organization. The request is submitted in writing. The application is required to compulsorily provide the following information:

• FULL NAME;
• the exact address of the user;
• passport details;
• phone (mobile or home);
• flowmeter type;
• the serial number;
• Installation act;
• the due date of an input device in operation;
• primary indications;
• calibration interval.

The above list is suitable for individuals. Legal entities, inter alia, the need to provide data relating to the company's location, as well as other required information.

How to seal water meter right? After the application it is necessary to wait a few days. After this period, the user must reach an employee of the management company and to conduct inspection of the meter. Next is the installation of the seal. Upon completion of this process, the master must provide the customer an act of oplombirovki completion. A copy of this document remains with the company. In both instances must necessarily attend the signature of the master and the client.

Flowmeters are used in cold and hot water supply networks, differ in construction and principle of operation. Experts recommend purchase equipment only in the case if the company is licensed to sell it. When buying a meter should take into account many important points, among which we should highlight the date manufacturing devices, the material body, matching the serial number on the instrument and in the documentation; t. d. Installation and oplombirovku flowmeter is recommended to professionals.
