Checking the water meter: who to call and what you need to know

Calibration of the water meter - a process aimed at measuring accuracy indications sacrificial carrier. Determination of serviceability of the device is a very important event, because the device at any time, may fail, leading to a distortion of evidence. Many people are interested in the issues of when to carry out verification of the meter, and by whom it is produced. To know the answer, you need to carefully examine the procedure for revision.

Verification of water meters: what is needed and by whom

verification procedure is governed by the legislation in force and is performed only by authorized municipal organizations. At the end of the inspection is drawn, indicating the results of the audit and the suitability of a particular application-metering device.

What is the verification of the water meter? If the counter did not pass verification, then admit it unusable. In such a case, necessary to replace the meter. Inspection of water measuring equipment is aimed at determining the accuracy of the data it records.

Most often negative results suggest devices whose service life has expired. Counters water a sophisticated design execution. Over time, their parts wear out under the influence of various unfavorable factors, which leads to a distortion of the accuracy of readings.

Measuring instruments may have different calibration interval. This parameter depends on the type of counter. For example, flow meters used in the networks of hot water supply, require more frequent inspections.

Note!A faulty device can underestimate like and inflate carrier flow data. Thus, periodic inspection of the measuring equipment is not only interested the management organization, but also the user.

Less is produced audit counters cold water. Timing verification is recommended to follow, despite the fact that the current legislation does not provide for penalties for their delay.

All water metering devices are the first verification of the plant where they are made. After a successful audit of the documentation that comes to the instrument, it indicates that the counter has shown positive results and is suitable for use. There's also prescribed date of the re inspection.

Calibration of the water meter range is set by the manufacturer. It is important to understand that the company produce counter, provides a guarantee on the device, so it is believed to be accurate reading until the next inspection.

Verification of water meters: the timing calibration and operation of the instrument

After the installation of water measuring devices for cold and hot water supply networks and introducing them into service, the user need not worry about the accuracy of the data recorded them. However, after a certain period, there is a need to conduct inspections of measuring equipment. The interval between the installation of the new device and the verification, as mentioned earlier, may be different.

Calibration interval of meters for cold water usually is 6 years. In turn, flow meters, which are installed in the hot water pipes can be used in all 4 years, after which there is a need to conduct inspections.

In some cases, consumption fail sooner than the period of their verification occurs. Most often the reason for this is the absence of the filter elements, the delay coarse particles in the system. This leads to rapid wear of the equipment.

Lifetime counters hot and cold water - a very important parameter, which is determined by the manufacturer. The duration of operation depends not only on the quality of the water metering device. This parameter is influenced by the following factors:

• flowmeter type;
• construction of the body material and structural elements;
• individual qualities of the media in the pipeline.

The increased pressure in the system and the presence of harmful impurities in the water - the basic factors related to the individual group that affect the premature failure of the flowmeter.

Note!low quality models, which are in contact with the carrier in the system may be damaged after only 2 years after commissioning.

Timing verification counter cold and hot water: nuances

Dates of verification must necessarily be specified in the documentation that comes with the measuring device. Thus, to know when it is necessary to carry out an inspection, simply find the data in the data sheet.

How else can determine the time of checking the hot water meter, as well as the device for cold-water? Necessary information can be found on the website of the local community services. Terms of carrying out inspections in certain cases specified in the receipt, on which there is a payment of utility bills.

Inspection of metering devices is recommended before the fixed date. In addition, the user can set a convenient date for it. However, in this case, it is important to remember that they do not conflict with the official calibration interval. How often do you need to do calibration of water meters? Inspect more frequently than once every 4 or 6 years, permitted, and less - no.

It is also possible situation that requires immediate unscheduled inspection of the water meter. The reason for this may be compromising the integrity of seals or mechanical damage to the device, affecting the accuracy of its readings.

Timing of verification specified in the data sheet are not always decisive. Existing regional laws may make changes to these data. Thus, it is recommended to study the laws corresponding to a particular region of residence.

It should be noted that the life of the hot water meter often less than the calibration interval. As a result, much more profitable after a certain period of time to carry out the complete replacement of metering device.

Calibration intervals Consider the most popular models of the counters. Domestic appliances often have a standard interval between revisions, which is 4 years for the domestic hot water flow meters and 6 years for the water measuring devices mounted on the cold-water network. These include products of such companies as:

• Pulse;
• Meter;
• IEDs;
• Pulsar.

Helpful information!water meters operating time varies depending upon the company and can reach 15 years (under normal use conditions).

There are foreign counterparts measuring equipment, which have a longer interval between inspections. For example, for Maddalena meters, the figure is 10-15 years (depending on model).

Those water metering devices that have not been calibrated within the specified period, subject to deregistration. It is also important to note that the payment service provider in the case of ignoring the inspection will be calculated in accordance with established national standards. Thus, the counter will not be considered valid.

Checking the water meter: how is the application for the inspection

Applying for an audit of the equipment used for the metering of water, it can be done in several ways. The first option involves the direct submission of the application in writing to the service providers. This method is more comfortable for the user as it does not require dismantling of the instrument.

The second option is less convenient because it implies dismantling the device. metering device in the delivery of municipal services produced forces the user. Verification of hot water meter or instrument for HVS require all the necessary documents.

It is important to remember that some of the counters can not be checked at home. This point is worth considering when choosing a meter. If the device meets all necessary requirements for the audit in the home, then the managing organization has no right to refuse to provide such services.

Application shall be made in accordance with a specific form, and must contain all the necessary data relating to a specific device. Contacting the utility service is made in advance (before the expiry of the deadline set by the manufacturer). Meter verification requires application drafting, in which are specified:

• F. AND. About user;
• the exact address of a natural person;
• meter type, and its model;
• meter serial number;
• the name of the manufacturer;
• user's phone number.

Permission to carry out the inspection of the water meter have the only organizations that have a license, confirming the right of such activities. If the device has not passed verification, then it involves the exchange of the water meter.

After the inspection (if the verification is not carried out at home), the managing organization is obliged to provide a specialist who will perform the sidebar device back to the highway.

Note!At the end of the master is obliged to provide the act of certifying equipment serviceability.

User is obliged to pay the cost of inspection of cold water meter. The same applies to calibration and hot water meters. After how many years is re-audit of water measuring equipment? Date of next calibration is specified in the documentation provided by the owner after the procedure.

A certificate attesting to auditing, must necessarily contain an image, containing the serial number. Also, the document must be signature of a particular specialist. After the inspection, the documents confirming the availability of water measuring devices, it is necessary to transfer to the municipal service that provides services to the user.

Calibration of the water meter at home without removing: notes

It is advised to study the sequence of actions that allow to carry out verification of water measuring devices. This will avoid the various contingencies. First the user must apply for a challenge to master, which will carry out an inspection. As a general rule, to meet the application takes 3 to 5 days.

Employees of municipal services should warn the user about the date of the arrival of a specialist. Before the start of the audit-metering device between the two parties is a contract stating the nuances of testing and its cost. Price water meter calibration can be different (from 450 to 1500 rubles.).

communal organization specialist is obliged to carry out an inspection pursuant to this agreement. During testing of the device master has no right to violate the integrity of the seal. Document confirming the conduct of the audit after its implementation is directed to the housing office.

This procedure is performed with the frequency calibration of the water meter. The operation itself does not take much time. Skilled craftsmen as little as 30 minutes to conduct an audit of water measuring device, as this procedure is not complicated.

As calibration takes place at home water meter: the steps of

The first phase of the audit involves the attachment of the mixer in the system of specialized equipment for verification. Such work may be suitable shower hose (with removed watering). Output device should be sent to a pre-prepared container whose volume should be approximately 2-3 liters. This reservoir is located on the scales.

Note!When inspecting the meter of cold water or hot water network device municipal officer is obliged to check the remaining water intake point. They should be closed. Before the beginning of the test meter, it is necessary to fix the preliminary indications thereon. This is an essential point, eliminates confusion.

The container is then filled with water from a faucet. After the calculated amount of water in the tank. After necessary to compare the received digits with the indications on the measuring device. This procedure must be repeated several times. This is done in order to reduce the error in the calculations to a minimum. If it meets the required standards, then the master points in the inspection certificate that the device is serviceable.

Too large error indicates that the device is not suitable for use. Such a device is mandatory to be replaced. Some flowmeters fail before the replacement period. Water meter wears out too quickly in the case where it is used under severe operating conditions.

Advantages and disadvantages diagnostic counters at home

The inspection of water measuring devices at home has its advantages and disadvantages. The main advantage, of course, you can call it that such a procedure does not require a lot of time. In addition, when such verification not only saves time, but also finances.

The inspection, which requires the dismantling of the flowmeter provides the cost of reinstallation and oplombirovku device. term water meter calibration in the laboratory, on average lasts 2 weeks. In any case, such a revision is not user-friendly.

If the counter is to check in a laboratory, then the service provided by the utility company, to be paid on the average performance. It also entails the extra financial costs.

Another advantage of checking water measuring device at home - impossibility damage plumbing assemblies. Dismantle the flowmeter can affect the performance of plumbing in the house. Before you start checking you should definitely take into account the service life of the water meter.

Helpful information!Citizens who belong to the privileged categories, most often provided low tariffs for carrying out inspection work.

Performing inspections on home water measuring equipment has also negative sides. The main one is the impossibility of a detailed assessment of the device. Home inspection does not allow to identify and prevent the implicit problems that may occur over time. Thus, the exact service life of cold water meters, as well as devices for domestic hot water can not be calculated. The owner is satisfied with only approximate data.

The rights and obligations of consumers when checking water meters

In various misunderstandings may arise during the verification of water measuring devices. In order to avoid them, you must get acquainted with the rights and responsibilities of consumers. This will allow an inspection of the equipment as much as possible correctly. It is the responsibility of the owner includes:

• carrying out verifications;
• Installation of the measuring equipment;
• appliance repair accounting and his replacement (if necessary).

The audit is performed taking into account the frequency of checks counters of cold and hot water. Inspect ahead of time is allowed, but should take into account the feasibility of such an act.

Residents of apartment buildings should not prevent employees of the managing company to verify the correctness of the data, which are fixed metering devices. To answer the question of how to believe the counters of cold and hot water, it is recommended to study the legislation, which can be found on the net without any difficulty.

Submission of data recorded by metering devices, must be carried out no later than the 25th day. This rule is necessary. If you ignore it, then pay for the service after 90 days will be made in accordance with the standard set by the utility service.

Time verification of the water meter should indicate the appropriate documentation. User is obliged to conduct an audit before the expiry of the calibration interval. Inspection date most often determined by a communal organization. However, the owner may also be affected at this time.

It is necessary to remember that the audit of water metering equipment confirms its usability. Thus, the user is interested in complying with the above provisions. Ignoring verification can become a reason to recalculate the cost of services.

Note!People who rent housing, also have the right to choose the way to check-metering equipment.

How much is the verification of a water meter at home and in the laboratory

All installation, maintenance, inspection, and replacement of water measuring equipment made with regard to legislation and the contract be drawn up between the owner and utility service. metering inspection can be performed at home or in a specialized laboratory.

The first option involves the arrival of a specialist in a particular address of residence. Such verification will cost an average of 650 rubles to the owner. The minimum cost for this service is 400 rubles. It is important to remember that to make verification of the water meter can be, and in the laboratory, but in this case its value will increase.

Typically, laboratory tests performed in the case where there is a suspicion that the device is out of order. Breakage of the measuring device must be removed after a diagnostic laboratory. During the calibration counter is set to place a temporary metal or polymeric tube. After repairing the meter communal organization is obliged to provide warranty. laboratory audit cost is from 500 to 2000 rubles.

Expiration operation counter to the water in the apartment is a signal that the device should be replaced. However, in some cases, such devices and spend several years in excess of the norm. Reading accuracy and proper function - the only factors that are necessary to be guided during the determination of the need to replace the device.

When to change the meter to the water? Some damage to metering devices to be fatal. In the event that there is no possibility of repair, the user must purchase a new device. Cost serviceable instrument in this situation is added to the cost of laboratory inspection.

Is it possible to free checking water measuring devices

Current legislation contains all the necessary information that describes the procedure during the inspection of water measuring devices. The relevant law states that municipal structures do not bear any responsibility for the conduct of the audit. Order this service is made only by the owner based on the term of service of the water meter. Payment for work also rests on the shoulders of the consumer.

Note!Management organization and the local water utility have the legal right not to notify the user of the expiration period of recalibration. No legal basis to support the information that the verification can be carried out free of charge, simply does not exist.

Inspection of water measuring devices can produce or utilities or private entities that have a license. This information is contained in the regulations. Timing verification counters hot and cold water as defined by applicable law.

Some individuals may encounter unscrupulous organizations that do not have the right to inspect measuring devices. Before you order the service from a specific firm, the client is recommended to check for the appropriate license.

How to identify unscrupulous executors? The determining factor may be the cost of services provided by a private company. For example, the price of less than 400 rubles, as a rule, indicates that the company does not have permission.

What if expired calibration water meter

This problem is quite common. Many users are not even aware of the need to conduct periodic inspections of water metering equipment. In addition, the individual may simply forget to perform this procedure in time.

If time does not carry out an inspection device, then his testimony becomes invalid by default. The delay period is fraught verification hot water meter and device for HVS? In case of default of its obligations the consumer pays that will pay for the service of general tariffs.

Fines for overdue inspection, which sometimes impose public service, are not legitimate. When appointing any sanctions the owner has every right to challenge the decision of the management company, filed a complaint with the appropriate authorities. It is important to remember that the user is not obliged to pay any fines. If any owner is obliged to submit a complaint to the managing organization.

If the life of the water meter has expired, then it is necessary to replace the device with the new. Payment for services under a common tariff will be made as long as the user does not carry out an inspection of the water meter. Therefore, experts recommend not to delay the resolution of the issue.

Where to send documents after check-metering equipment

Before answering this question, it is necessary to deal with the list of documents that must be in the hands of the user. Consider the list of documents in more detail:

• Device passport;
• act of delivery and acceptance;
• certificate of carrying out calibration.

The passport, which is attached to the flow meter, should contain the following: manufacturing date, time, device commissioning, as well as the expiry date on the water meter.

Helpful information!In the act of delivery and acceptance specified serial numbers, date of tapping device in the trunk, user data and the management organization. This document must contain both audio signatures and the second side.

The original calibration certificate lists all the necessary data to support the device serviceability. This certificate must contain the date of the inspection. In addition, it specifies the period performing re-examination. Counters hot and cold water have different calibration interval. That they should orient the user on subsequent executions of this operation.

All of the above documents must be sent to the managing organization. In addition, such issues are handled by the HOA, so the device can register the account and in the organization. The next step is the submission of documents to EIRTS.

Verify or change: the feasibility of verification procedures

Domestic operating conditions are often unfavorable, leading to rapid failure of the counters. The most vulnerable elements constructions water-metering devices are parts made from polymeric materials. Many flowmeters fail earlier than the end of their service life. Water meters vulnerable parts are worn during operation, can not be repaired.

Even if the device has been inspected, there is a high probability that it will fail sooner than will the next revision. The real life of hot water meters and flow meters that are installed on the HVS below the network than the one indicated by the manufacturer. Increase this figure makes the installation of a strainer in front of water measuring device.

From all the above it follows that after a certain period of time necessary to carry out inspection of metering devices. However, they quickly wear out, as they often are in direct contact with water, which is contaminated with foreign particles. As a result, the user runs the risk of wasted money spent for the audit, which revealed that the device is unusable.

Thus, checking of counters, hot water and devices for the HVS is not always a viable solution. Because the cost of the new device is not so great. Inexpensive models can be purchased for 500 rubles. Cheaper to replace an old appliance with a new one than to spend money and not get the desired result.

Inspection of water measuring equipment is needed surgery, which is performed in accordance with the terms set metering equipment manufacturers. Counters for cold-water and hot water have different Calibration interval. It is necessary to know in order to avoid confusion. Conducting the verification procedures carried out in accordance with steps.
