The Association assists in providing services in the sale of timber: at competitive prices for permanent basis. Forest products of excellent quality.

After commissioning of the metering unit, a contract for the maintenance of thermal energy metering units is drawn up. As a rule, this is done by the design and installation organization that carried out the installation and maintains the ITP.

We carry out all routine maintenance work, as well as installation of UTE at a high professional level.

Technical (service) maintenance of ITP and UUTE is necessary to maintain the operability of the equipment, prevent accidents, ensure uninterrupted reading of indicators and control over the parameters of the equipment and coolant.

Maintenance of thermal energy metering units allows you to avoid possible misunderstandings in the event of a discrepancy between the calculated and actual consumption of thermal energy. Such situations sometimes arise when heat and power enterprises somewhat distort indicators and try to write off at the expense of consumers additional expenses. In such cases, the price of the UTE and the cost of maintaining the UTE quickly pays off.

As practice shows, professional and competent maintenance of equipment allows not only to reduce operating costs, minimize the risk of breakdowns, but also significantly reduce electricity consumption. It is calculated that regular maintenance at ITPs with UUTE makes it possible, in some cases, to reduce the average annual electricity consumption by 30%.

Routine maintenance of UUTE includes the following services.

1. Scheduled follow-up inspections.
2. Unscheduled control inspections.
3. Maintenance of UUTE components.
4. Daily remote (if technically possible) recording and analysis of readings from metering devices.
5. Interaction with representatives of the heat supply organization.
6. Monitoring the timing of verification of control and metering devices.

Maintenance of thermal energy meters

The thermal energy metering unit consists of a heat quantity calculator, resistance thermal converters, primary flow converters, pressure converters, sensors, measuring instruments and auxiliary equipment (power supplies, controllers, etc.).

Maintenance of heat metering devices is carried out during one of the control inspections at least once a month. It is divided into external inspection and preventive maintenance of heat meters.

During the external examination the following is carried out:

• visual inspection to identify mechanical damage and malfunctions;
• checking for the presence and integrity of seals;
• checking for changes not included in the project;
• checking the operating conditions and condition of the place where the UTE was installed;
• taking readings and recording them in a journal.
• cleaning the room and installation site of the UUTE from foreign objects that interfere with maintenance.

Preventative maintenance includes:

• cleaning equipment from dust;
• testing the counting mechanism;
• checking the configuration (settings) of the computer;
• setting and testing converter output signals;
• checking the computer for the presence of programmable distortions;
• checking the mains voltage;
• checking the grounding and pipeline for absence of voltage and potential difference;
• eliminating possible leaks and checking shut-off valves;
• release of water from the general valve to the unit.

Violation of frequency or regulations Maintenance Thermal energy metering devices can be expensive. Minor, easily repairable damage that is not detected in time can, after some time, cause a serious accident requiring the replacement of expensive ITP and UTE elements.

Service installation of communal metering units in apartment buildings, HOAs, housing cooperatives, management companies, organizations and enterprises.

The warranty period for the devices included in the metering unit ranges from 1.5 to 4 years. Typically, the instrument manufacturer specifies that it carries warranty obligations, if installation and commissioning work was carried out by a specialized organization.

If the installation of metering units is carried out within the framework of a municipal program, then, based on a competitive selection: a municipal contract is concluded with several such specialized organizations, the terms of which include the requirement to provide a five-year guarantee for the work and equipment performed.

Specialized organizations, often service centers of manufacturers, sign such a contract, thereby extending the warranty period to five years at their own risk. At the same time, they expect that they will be the ones who will be involved in the technical maintenance of the metering units installed by them.

The other side of the municipal contract presents a different perspective: the components are new and in good working order, and if something breaks, there is a five-year warranty. Hence, further operation in the next five years seems no more difficult than collecting readings from meters at the end of the reporting period.

Apparently, the very idea of ​​paying money for the maintenance of metering units to the company that performed the installation and gave a five-year guarantee for the work performed seems absurd.

Based on such a simplified idea of ​​​​the further operation of metering units, the tariff includes 16 kopecks per square meter for service. This is approximately 500 rubles per month for servicing the metering units of one apartment building.

To provide maintenance services, a new organization“The best service organization in the city of Vladimir” (conditionally), which, under an agreement with management companies, undertakes to monitor the condition of seals and shut-off valves twice a month, as well as collect meter readings at the end of each month.

Service centers, of which we are one, offer a really necessary range of services average cost 1500 - 3500 rub. per month per metering unit, but most of management companies gives preference to “five hundred rubles”, without delving into the contents of the contracts.

However, after two or three months, a massive refusal of the services of “The Best Service Organization of the City of Vladimir” began and a transition to the services of service centers, that is, to the services of specialized organizations trained by the manufacturer.

What is the reason? The reason was that the energy supply organization refused to accept for calculations the readings of many metering units, which were taken by the “Best Service Organization of the City of Vladimir”, we note, with a preliminary inspection of the condition of the seals and shut-off valves.

If the “Best Service Organization of the City of Vladimir” fulfilled its contractual obligations in in full, the warranty on devices and installation is valid, but there is no commercial accounting, then the reason is apparently malfunction service organizations.

Considering that the country is undergoing a massive introduction of metering units, I believe that this story may turn out to be useful topics who will be involved in servicing metering units or organizing maintenance.

How to organize maintenance so that meter readings are accepted by the energy supply organization?

Let's start with Federal Law RF dated July 27, 2010 No. 190-FZ “On Heat Supply”. Article 19. Organization of commercial metering of thermal energy, coolant, establishes that the organization of commercial metering may include:

1) installation of metering devices;

2) operation of metering devices, including taking readings from metering devices and transferring them to customers of this service, verification, repair and replacement of metering devices.

Another document. Rules for accounting of thermal energy and coolant from 1995. Clause 9.3. “maintenance work on the metering unit associated with the dismantling, verification, installation and repair of equipment must be carried out by personnel of specialized organizations...”.

It follows that in addition to taking readings from metering devices, the responsibilities of the service organization must include the provision of services for the repair and replacement of metering devices, regardless of the availability of guarantees from the installation organization and the manufacturer. Warranty repair will be performed free of charge, but first the service organization must establish that the cause is a malfunction of the device. Next, correctly fill out the complaint report, dismantle the device, and replace the device sent for repair with a working device from your reserve replacement fund.

Verification of measuring instruments, in accordance with Article 13 of the Federal Law “On Ensuring the Uniformity of Measurements”, is carried out by those accredited in the prescribed manner in the field of ensuring the uniformity of measurements legal entities. Service organizations do not have such accreditation, but for devices to be verified, they must be properly dismantled, prepared for verification, and after verification, reinstalled in the metering unit. Therefore, it is advisable to include this position in the responsibilities of the service organization.

But that is not all. Heat supply is complex technological process. Hence the complex commercial accounting. The readings from working instruments cannot always be accepted for commercial calculations. Reasons?

Article 2 of the Federal Law of the Russian Federation of July 27, 2010 No. 190-FZ “On Heat Supply” establishes the following concepts:

The quality of heat supply is a set of standards established by legal acts RF and (or) heat supply agreement, heat supply characteristics, including thermodynamic parameters of the coolant.

Thermal energy consumption mode is the process of consuming thermal energy and coolant with the thermal energy consumer observing the mandatory characteristics of this process in accordance with legal acts, including technical regulations and the terms of the heat supply contract.

Article 15 of the same law establishes that the heat supply contract must determine, among other things:

The magnitude of the heat load of the consumer’s heat-consuming installations, the parameters of the quality of heat supply, the mode of consumption of thermal energy;

Responsibility of the parties for non-compliance with the requirements for heat supply quality parameters, violation of the thermal energy consumption regime, including responsibility for violation of the conditions on the quantity, quality and values ​​of the thermodynamic parameters of the returned coolant.

Rules for accounting of thermal energy and coolant from 1995. Clause 1.3. establishes that calculations for the received heat are carried out on the basis of readings from metering devices and control of coolant parameters. Clause 1.4. establishes that mutual obligations for settlements for thermal energy and coolant, as well as compliance with the regimes for supply and consumption of thermal energy and coolant are determined by the contract....

Since it is obvious that non-compliance with consumption regimes will negatively affect energy efficiency, we will also point to Article 9.16. Code of the Russian Federation on administrative offenses, which establishes liability for non-compliance with the energy efficiency requirements for apartment buildings.

From the given links it follows that the consumer can pay the energy supplying organization according to meter readings only if there are no violations of the consumption regime, there are no violations of the “conditions on the quantity, quality and values ​​of the thermodynamic parameters of the returned coolant.” Otherwise, there will be a fine or an additional charge, it all depends on the heat supply agreement. There is another option - decommissioning metering devices, with the ensuing consequences. Let us consider this option in more detail, since it relates to the maintenance of metering units.

So, the energy supplying organization determines the presence of mode deviations based on meter readings. There is a legitimate doubt here. Are there really violations in the intra-house system that the device registered, or is the device lying, but everything is in order in the system?

Let's turn to everyday experience. Do we know of cases of coolant leaks in intra-house systems? Yes. What should the device record? It will record the difference in mass between the coolant received from the system and returned back to the system. Is this a violation of the regime? Yes.

Are there known cases of unbalanced hydraulics in an intra-house system? Yes, many people know that when it is cold in some apartments, you need to complain, then the nozzle that limits the coolant flow will be drilled out. It will become warm in “cold” apartments, and hot in “warm” apartments, but excess heat can be easily removed through the window. What will the device register? Violation of “conditions on the quantity, quality and values ​​of the thermodynamic parameters of the returned coolant.”

Is there another solution known - to drain the coolant from the return pipeline into the sewer? What should the device record? The difference in mass between the received and returned coolant. Is this a violation? Certainly.

If everyone knows that the state of in-house engineering systems is far from perfect, then can it be said that guaranteed, verified devices with seals can be trusted without a doubt?

Unfortunately no. If there are malfunctions of in-house systems, then there are repairs. When carrying out welding and plumbing work, scale, rust, pieces of rubber, and other foreign objects enter the system: they get stuck in the metering unit and create conditions unacceptable for the operation of the devices, which leads to loss of measurement accuracy. The device does not require repair, but it is necessary to restore its operating conditions.

We conclude that the reason for instrument readings that are unsatisfactory to the energy supply organization may be either a malfunction in the system or a loss of measurement accuracy.

How does the energy supply organization resolve these doubts? Just. When monitoring the consumption mode for commercial accounting purposes, the energy supplying organization is indifferent the real reason faults, it considers only the actual readings of the instruments, and not the reasons that led to such readings.

If the reliability of instrument readings is in doubt, then the energy supply organization can remove the unit from commercial accounting, referring to clause 9.10. TE&T accounting rules “work beyond accuracy standards”.

For example, in a closed system, by definition, there should be no difference in mass between the supply and return pipelines. If there is a difference, then the device is faulty. This is the logic. The logic is acceptable, since both the devices and the in-house system are beyond the responsibility of the energy supply organization.

We've reached a key point. The energy supplying organization removes metering units from operation only when it has reason to doubt the reliability of the instrument readings, because these readings do not meet the expectations of a normal process.

Conclusion. This means there should be no evidence that can be doubted. No falsifications! There is another only correct solution. We need a maintenance technology that allows us to monitor readings and eliminate the causes of questionable readings immediately as they arise.

This conclusion underlies the organization of servicing of metering units by our enterprise.

The main task of maintenance is to ensure normal, continuous operation of metering units, in which all parties trust the metering results. Whether you like or dislike the accounting results, and the parties trust (are forced to trust) the results are different concepts.

Let's go to the area practical implementation this task.

To eliminate the causes of questionable readings as they arise, it is necessary to detect them as they occur. This means that software and hardware are needed that allow continuous monitoring of the parameters of all metering units at a pace acceptable for solving the task. Without the ability to monitor, the task is impossible!

We use automated system information collection as a top-level system and data transmission equipment. Communication with some metering nodes is carried out via modems. Data collection is carried out automatically every day at night after midnight. At the operator's request, you can download the readings at any time.

The key figure is the person performing dispatch functions. This is an analyst who is able to see the process of heat and water supply and deviations in consumption patterns behind columns of numbers and multi-colored graphs of parameters. The program automatically detects some deviations in parameters, but the human brain remains the most powerful analytical apparatus.

Control is not reduced to a primitive assessment - “there is evidence” or “there is no indication”. The absence of indications is an unpleasant, but the simplest case when the cause can be easily identified and quickly eliminated. It’s more difficult when there are indications. How to determine that these readings can be trusted?

Since the metrological characteristics of devices cannot be determined at the place of operation, the “quality factor” of the readings is continuously assessed. By “quality factor” of readings we mean compliance with expectations of the magnitude and dynamics of changes in controlled parameters over time, as well as the relationship of changes between dependent parameters.

If readings are detected that do not meet the “quality factor” criteria, the dispatcher sends operational personnel to the site, who on the spot finally determine what was the cause of such readings - incorrect measurements of the normal mode or correct changes in the abnormal mode.

Thanks to monitoring, personnel sent to the site know in advance what actions they must take and have with them components for replacement, if necessary.

It is important that the staff knows not only the devices, but also knows how to identify and convincingly prove a malfunction in the in-house system with obtaining a confirming signature from a representative management company. This encourages (but does not guarantee!) prompt elimination of faults in the intra-house network and protects the service organization from claims against metering devices.

So, the key point of service is that the service, management and resource supply organizations equally trust or distrust the readings of metering devices, assessing their quality factor.

If the service and management organizations promptly eliminate the causes that resulted in bad readings, then commercial accounting becomes continuous and long-term.

Let's summarize minimum requirements, which must be met by a service organization capable of providing long-term and continuous commercial accounting:

The organization must have the technical ability to continuously monitor serviced metering units;

The organization must have trained personnel capable of assessing the “quality factor” of the readings obtained during monitoring;

The organization must have trained personnel capable of distinguishing on-site malfunctions of the heat supply process from malfunctions of metering devices;

The organization must have personnel trained by the device manufacturer and authorized to service and minor repair these devices;

The organization must have a sufficient reserve fund for the prompt replacement of faulty devices;

The organization must be a service center for the manufacturer whose devices it services;

The organization must have many years of experience in this area.

If anyone today is experiencing difficulties in choosing a service organization to organize the maintenance of metering units, then I recommend taking into account the stated requirements or simply contacting our organization Energouchet LLC. This will save you from many unnecessary problems that interfere with real energy saving.

Based on the above, we carry out the following work:

1. Periodic maintenance of thermal energy metering unit devices (inspection, taking and analyzing readings, additional settings, adjustments, minor maintenance, checking electrical connections, checking the oil level in temperature sensor sleeves).

• Do we need a service organization?
• Is there a law requiring it?
• What awaits us if we refuse the service?
• What is included in the maintenance service?

Let's look at all the questions in order.

The heat meter does not require special care on the part of the owner. The lithium battery from which the heat meter is powered is not suitable for reuse, but requires disposal. The battery does not require special care; the service life declared by the manufacturer is at least six years, usually no more than five years, and this is equal to the service life of the meter before it is checked (the state verification period is four to five years for different heat meters). A specialist checking or servicing a heat meter is required to change the battery approximately every four years. If your flow converters are also powered by batteries, then they need to be changed every two years.

Thermal resistances do not require maintenance.

This is a theory - let's look at it in practice.
