How to adjust the heat meter

Knowing how to adjust your heat meter can make a big difference in keeping your home comfortable and energy-efficient. The amount of heat used in your home is measured by your heat meter, sometimes referred to as an energy or heat calculator. Accurate readings are ensured by properly adjusting it, which helps you control your energy use and minimize your utility costs.

Although it may seem difficult, adjusting your heat meter can be a simple process if you have the correct advice. It’s crucial to know how to calibrate your heat meter whether you want to maximize comfort from your heating system or strive for more accurate billing. We’ll show you how to properly adjust your heat meter in this article, giving you the power to manage the insulation and heating in your house.

It’s important to comprehend how your heat meter functions before beginning the adjustment process. The heat meter, which is usually placed close to your heating system, calculates how much thermal energy is used in your house. Utility companies then use this information to determine your energy bills. You can be sure that you’re getting an accurate bill for the energy you use by making sure your heat meter is calibrated correctly.

Taking into consideration modifications to your home’s insulation or heating system is one of the main reasons to calibrate your heat metre. The efficiency of your heating system can change over time due to a variety of factors, including seasonal fluctuations, renovations, and equipment wear and tear. You can account for these variations and keep your heat meter operating at peak efficiency by adjusting it from time to time.

As you can see, there is a new term here – heat calculator. Let"s explain what it is.

The term "heat meter calculator," or just "heat meter," refers to the component of the heat meter that receives signals from its sensors and provides computation, conversion, and data accumulation on the coolant parameters and the amount of heat energy (exactly those Gcal for which you pay).

As a result, according to heat metering regulations, a heat meter is a device that measures heat energy and can either be a single unit or be made up of different components depending on the project. These components include temperature and pressure sensors, heat calculators, and flow converters (flow meters, water meters).

To clarify, there are two ways that heat meters can be installed.

Heat meters can be purchased as a single unit that requires complete factory assembly and adjustment, or they can be purchased as individual components whose parts are chosen at the design stage.

Examples of complete factory-assembly heat meters are Multikal, Elf, ESCO-T, and Karat-compact. Block TMK-N, Vzlet, TSC7 (calculator VKT7), etc. There is no distinction between them in the eyes of the customer. Block heat meters are chosen during the design phase because their scheme is more adaptable and their components can be chosen for a range of operating environments. Heat meters with full factory assembly, or monoblock, are typically used in offices and apartments because they practically never need to be adjusted (the database can even be changed) and can be operated with very accurate measurements even without it.

In order to understand the principle of setting the heat meter to the set parameters, let us describe the main parameters programmed before commissioning.

The weight or cost of the pulse in m3/imp is the first and most important one. The flow meter, water meter, or flow transmitter’s passport contains information about the pulse price. The kind of water meter and the length of its pulse are equally significant parameters.

The measurement scheme, or algorithm, is the next parameter. It is this that determines how the heat meter’s heat calculator will compute the information gathered from the temperature, flow, and pressure sensors, which are the main converters. This is, in general, the heat formula that the heat calculator uses to calculate counts. It is chosen from among the variants that are pre-programmed at the factory.

In heat meters with full factory assembly, these are the two parameters that are pre-programmed at the manufacturer’s factory.

The following are the primary parameters, to which all others are supplementary:

  • The pressure of the heat carrier if it is not measured, and it should be measured only at metering units over 0.5 Gcal/hour. Of course, you have the right to install sensors that transmit readings to the heat calculator yourself (I mean to stipulate in the technical task for design), but this is extra money for installation (about 15 tons). The accuracy of measurements will not be affected much, about 0.01%.). They will not affect the accuracy of measurements much, about 0.01%.
  • Then there are maximum and minimum measurement limits (in heat meters of full factory assembly they are programmed at the manufacturer"s factory).
  • Time of report generation in the heat meter or reporting date and hour.
  • And lastly, the so-called contractual values – parameters of heat billing stipulated in the heat supply contract. This also includes cold water temperature If you do not have the right to change the temperature of cold water at the heat source (boiler house), it is entered into the calculator as a constant, and in accordance with the contract, the amount of heat consumed by you must be recalculated periodically taking into account the actual temperature of cold water. The above applies to open hot water supply systems, which is when you take hot water directly from the heating system.

And finally, a note regarding the function of the service organization in the response. Although she isn’t allowed to alter the heat meter on the heat metering unit, it is preferable to give her authority over any modifications made to the heat calculator database. Professionals from service companies are frequently more knowledgeable than those from heating networks. They can advise you on how to properly challenge the heat supplier’s actions, and most importantly, whether it is worthwhile to do so in order to reprogram the heat meter. This is especially true if the actions have resulted in an apparent increase in heat bills.

You can make sure your heating system works as efficiently as possible with these easy adjustments, keeping your house warm and reducing energy waste.

Trust, but check: heat meters for heating in an apartment building, the principle of operation of devices

A heat meter is a multipurpose microprocessor that has been designed to determine the temperature.

These devices ought to be installed in every home with central heating as well as at central heating plants, per energy-saving standards.

Why a heat meter is needed and how it works in an apartment building?

Heat meters are used to regulate the heating services’ quality. You won’t be required to pay the full cost of heating your house if the batteries weren’t heated sufficiently.

With utility rates constantly rising, having an individual meter will result in significant cost savings. These kinds of devices have long been installed by heating plants in order to regulate the quality of services.

Heat meters are required for apartment buildings in order to incentivize residents to adopt energy-saving practices. By installing a heat meter, you can assess how well the heating medium is supplied throughout the house, as well as identify and get rid of any potential losses due to poor gasketing and heat pipe deterioration.

Varieties of heat meters according to the principle of operation

Large, pricy devices called general heat meters are placed in homes with central heating. Because they permit a lot of heat transfer fluid to flow through them, their pipe inlet and outlet diameters range from 32 to 300 mm. The cost of purchase and installation falls on the homeowners, and either a utility company representative or a responsible individual chosen by the homeowners will keep an eye on the readings.

Persona Heat meters cost a lot less money. They are made to be much more compact and have a smaller capacity—no more than three cubic meters per hour.

These devices can be installed for each battery individually (in the event that there are multiple vertical risers) or for the entire apartment (in the event that the heating system is horizontal).

Apartment heat meters are frequently installed during the building phase of new residential complexes.

Temperature and flow measurement sensors, as well as a calculation module, are included with every heat meter. However, the meter can be any of the following types in accordance with the principle of measuring the quantity of the flowing thermal fluid:

  • Electromagnetic;
  • mechanical;
  • ultrasonic;
  • vortex.

Regarding design features, there are benefits and drawbacks for every kind of device.

electromagnetic

Electromagnetic induction forms the basis of the measurement principle. The apparatus is a hydrodynamic generator. The magnetic field’s effect causes an electric current to be excited in the water, and the potential difference between the electrodes that are negatively charged and the strength of the field determine how much heat is produced. Due to its high sensitivity, the heat meter needs to be installed with extreme care and requires frequent maintenance. Error in readings appears upwards in the absence of regular cleaning.

Picture 1 shows the Thermo-Fort electromagnetic heat meter Fort-04 with two flanged flow meters.

The heat meter can respond to adjacent electronic devices. has excellent accuracy when accounting for a wide range of factors. uses a battery or the mains to operate. the smallest kind of heat meter. Installation at higher system pressures is advised. Any angle can be used for mounting, as long as coolant is continuously present in the installation area.

Reference: Adapters may be used if the pipe diameter heating and the meter flange mismatch.

Mechanical

Such a device has a rotating flow meter (impeller, turbine, or screw). The mechanism works on a similar principle to a water meter, but it also considers the temperature of the water as it passes through the mechanism. The following are advantages of this kind of appliance:

  • low cost;
  • non-volatile (powered by batteries);
  • absence of electric elements (allows installation in unfavorable conditions);
  • vertical mounting option.

The mesh filter installation is a little more expensive but necessary because without it, the internal mechanism wears out and clogs easily. Measuring mechanically is limited to individual meters due to rust contamination of the coolant and impossibility of application at high hardness.

Not storing data daily and not being able to read data remotely are considered significant drawbacks. Furthermore, compared to other types of models, the device exhibits a higher pressure loss in the heating system and is highly susceptible to hydrostatic shocks.

Ultrasonic: can measure and regulate

Ultrasound is used to carry out the measurement. The amount of time it takes for ultrasonic waves to travel from the transmitter, which is positioned on one side of the pipe, to the receiver, which is on the other, varies according to the coolant flow rate. The hydraulic pressure within the system is unaffected by the device. A clean heat carrier has very high measurement accuracy and almost infinite service life. The error of the heat meter data rises in the presence of dirty water or pipes.

Picture 2: A.C. Electronics Ltd.’s ENKONT ultrasonic heat meter with a stainless steel primary flow transmitter.

Such a meter is very informative, and it has the ability to read readings remotely. However, since the UPS can only be powered by the grid, you will have to spend money on it. Certain models come equipped with the extra feature of controlling the water supply via two distinct channels. This enables you to adjust the radiators’ heating intensity and coolant speed. Despite their high cost, ultrasonic devices have become widely used due to their dependability.

Vortex

The physical phenomenon of the meter vortex formation when water meets an obstacle is the basis for the principle of operation. A little further along the heating medium’s flow is the measuring electrode, the triangular prism positioned vertically in the pipe, and the engaged permanent magnet outside the pipe.

As water flows around the prism, it creates vortices, which are pulsating variations in flow pressure. Data regarding the volume of the heat carrier that has traveled through the pipe is shown based on how often they form.

This kind of heat meter’s benefit is that it is not affected by contaminated water or pipes. This allows for accurate temperature measurement in older homes with rusted iron heating pipes.

Installed on pipe sections that are both vertical and horizontal. The only things that can interfere with the device’s functioning are abrupt variations in the coolant supply’s speed and big debris or air particles in the system. A single battery can power a device for several years with very little energy consumption. Radio communication is used to transmit readings and fault signals from a distance.

Metering of the required amount of heat in the apartment

A heat meter is used to calculate the amount of heat. The following variables affect the program’s algorithm, which determines how it operates:

  • type of heat carrier in the system (vapor or liquid);
  • type heating systems (closed or open);
  • structure the system through which the heat is dispensed.

The computation is relative since it is composed of several discrete quantities, and errors (usually up to ±4%) occur at every step. The heating medium provides heat to the rooms as it travels through the heating system, and this heat is what is deemed to have been consumed by the consumer. This is the basis for the measurement principle.

When the mass of the heat carrier that passed through the device is taken into account for calculation, the quantity is measured heat in Gcal/h (gigacalories per hour), or kWh (kilowatts per hour) if the volume was recorded. In line with the subsequent formulas:

Either Q=V×k×(t1-t2) (in kWh) or Q=Qm×k×(t1-t2)×t (Gcal/h).

Mass in tons is represented by Qm.

The inlet temperature (t1),

Outlet temperature (t2),

V is the cubic meter volume.

T is the time in hours.

K, or the GOST heat coefficient,

Q: How much heat is provided to the space?

Main requirements for apartment devices

Laws and regulations are the primary requirements for heat meters. The appliance’s brand must be listed in the register of appliances that are acceptable for commercial use. Getting an answer from the state service metrology is essential. Only businesses with the necessary licenses can install heat meters.

It’s crucial! Every four years, metering device verification is done. The readings won’t be considered if the date is left out.

Useful video

Watch the video to become familiar with the key components of installing a heat meter.

What to focus on when choosing a heat meter for heating?

Prioritizing the needs of each individual device is important. If a group Buying an apartment with a heat meter is not worth the expense if you don’t need one. If the homes are not insulated beforehand, there is minimal use of the metering device in corner rooms and on the first and last floors. The cost of installing a meter will far outweigh any potential benefits in the case of a vertical heating system with individual risers in each room.

If the gadget needs to be purchased quickly, consider the following factors when making your decision:

  • sensitivity to dirt in the heat transfer medium;
  • energy independence;
  • measurement error;
  • pressure loss;
  • length of straight sections of heating pipes;
  • Archive availability and depth;
  • self-diagnostic capability.

Furthermore, it is crucial that the average consumer has access to the means of operating and verifying readings. If the manufacturer extends the warranty past the typical two years, that is a positive indication.

Most contemporary heat meters satisfy the specifications. The only thing left to do is select a fair price.

A vital first step in guaranteeing precise measurement and equitable allocation of your home’s heating expenses is adjusting the heat meter. You can make sure that your heat meter is correctly calibrated and giving accurate readings by following a few easy steps.

The first thing you should do is read the user manual that came with your heat meter. This will give you detailed directions on how to open the settings menu and make changes. It’s crucial that you carefully follow these directions to prevent breaking any warranties or harming the meter.

Next, choose your heat meter’s parameters carefully, taking into account things like your home’s heating system type, room size, and climate in your area. The heating fluid’s flow rate and the temperature differential between the supply and return lines are two examples of these parameters.

After gathering this data, you can start the process of making the adjustments. Usually, to do this, you have to open the heat meter’s settings menu and enter the right values for the parameters you’ve identified. Certain meters might let you adjust the settings right on the device, while others might need you to link to a computer or mobile application.

It’s crucial to keep an eye on your heat meter’s performance after entering the new parameters to make sure it’s measuring heat usage correctly. Over time, additional adjustments might be necessary to take into account modifications to your heating system or your living environment.

You can make sure you are only paying for the energy you really use and prevent disagreements with other tenants or landlords about heating expenses by taking the time to correctly adjust your heat meter. This easy action can encourage equitable and open billing procedures and ultimately result in increased efficiency and savings.
