How to install the water meter

Sooner or later it had to happen. Because of the limited natural resources, when humanity comes close to a complete destruction of some of the them many world states had to take a course on the general economy and the rational use of these gifts nature. Program saving energy and water resources are successfully operating in many foreign countries, while only similar trends are emerging in Russia.

In fact, almost half of all the water in our apartments leaked "wasted", and the heat from the radiator comes with a surplus, which also fly through the open window. Judicious use of water systems can reduce their use to pay expenses almost doubled, however, it requires a competent and accurate records, which can lead the way, with the help of water meters.

Household water meters installed in the apartment, to help gain some disciplined use of natural resources as well as a man realizes how much and for which he specifically pays. In any case it helps to reduce the cost of water, as well as its heating - this will save another, and electricity.

At the same time, the problem of water conservation at the household level is practically resolved at the legislative level. Today, a typical philistine prefers to overpay and enjoy unlimited amount of water, rather than save and spend the required minimum. However, this does not prevent you to install water meters on a voluntary basis and start to benefit not only your budget but also all over the world around now.

Installing water meters: step by step guide

Installing a water meter in an apartment - is not the most complicated process. Theoretically, it is possible to do it, and with his own hands, but it is best to turn to professionals, giving a guarantee on operation of the device and to carry out his service in the future. Consider the procedure in order.

1) First of all, assess the condition of water supply networks in your apartment. Currently, many houses built during the time of perestroika, coming close to the need of urgent repair. For the installation of water meters is important that the pipes were in good condition, without a "fistula" and prognivany. Must function and taps, by which shuts off the water in the home.

2) Now you can go to the DES or other organization responsible for housing management, with the aim of submitting the application for the installation of water meters in the apartment. Here it is necessary to clarify whether there are in your home brownies metering devices - without their presence inside apartment of cold water flow will be impossible. After applying the draft treaty drawn up between the owner and property management company, which spells out the rights and obligations of both parties. After that, do not rush to leave - always check with the representatives of Deza, which is a counter suit for utilities to your home. Write down the exact name of the model.

3) entrust the installation of the device is best licensed organization that deals with this professionally. Here again specify what kind of water meters need to buy - many organizations work only with certain modifications. In most cases, once installed in apartments two counters - for both cold and hot water. On the day of installation do not forget to invite the representatives of Deza - it will be a three-way act of reception counters into operation, after which it will be possible to start using the device officially. Finally, check with the installer, how it will be carried out maintenance and repair of equipment.

4) After the installation of the equipment must be concluded two more contracts with the organizations in which you will be paying a supply of hot and cold water. For the supply of cold water or wastewater meets all the same DES or other entity managing the Housing. under such contract obligations are defined in the regional legislation. For residents of Moscow that decision №77-PP.

Another agreement signed with the company responsible for water heating. In Moscow, it is the State Unitary Enterprise "Mosgorteplo". Please contact the district office of the organization and declare their willingness to pay for hot water for the water meter readings. The representative of the organization is obliged to report to you within a few days and put in a hot water meter extra seal. At the same time the contract is made, and the payment terms are negotiated over the counter.

5) If your home is managed by a different format (not DES), it is necessary to register the contract in EIRTS (Joint Information Settlement Center). Also tack with related documentation - passport counters acceptance certificate, etc... In EIRTS you put on the account and give instructions for submitting data to the devices in the future.

What types of water meters are there?

Today, the market of this type of devices has grown so much that the select counter for water is often extremely difficult. Already, in the territory of our state recorded more than 500 kinds of instruments of domestic and foreign production. When this is not enough to navigate the manufacturer - you must know first of all what type of device suits you. From this it depends largely on the price, the accuracy and reliability of the device. So, let's see what types of water meters exist.

Tachometer water meters

Water meter of this type is also called mechanical. In fact - it is the simplest arrangement in which the pressurized water stream rotate the turbine blade or vane wheel connected to a counting device through the gear.

By the way, it is the mechanical water meters are most commonly used in the domestic environment. Because of their simplicity, they are very affordable, reliable and precise enough. Thus there exists several varieties tachometric counters, operating on the same principle but differing in design. This turbine, single-jet and multi-jet water meters.

The simplest and cheapest of all - it is single-jet mechanisms. In devices of this type blades are arranged perpendicular to the water flow, which rotates them. The turbine impeller blade is located at a smaller angle - they are called Woltman meters. The most expensive are considered multi-jet mechanisms, passing through which the stream is divided into several jets. This greatly reduces the error counts, especially in comparison with cheaper counters.

Mechanical meters can be either "dry", and so "wet". "Wet" counters are arranged in such a way that the counting device is constantly under the influence of even the water flows and not isolated from it. In fact, it is in no way interferes with their work and did not affect their durability, but only if the water - clean. Dirty stream very quickly clog the mechanism and rendering it unusable. However, the price of these devices is minimal, and they are perfect for everyday use. The majority of single-jet meters - "wet".

"Dry" water meter is more reliable, even if used in contact with the muddy water. The fact that the counting mechanism is sealed and isolated from the stream. A transfer of information on it is done with a magnet placed on the blades or a turbine. Logically, the "dry" mechanisms can be used in any environment without the risk of clogging, but they are much more expensive "wet". This is why in the "odnostruyniki" they practically pose.

There are also "moist" water meters, a counting mechanism which is isolated from the water flow no partition, and a layer of a viscous water-repellent substance, in which it directly and is. Such devices are more affordable in price, rather than full-fledged "suhohody".

There are other modifications tachometer counters. For example, it combined, and combining the wing turbine system. If the water flow is weak - running impeller, while at high pressure turbine is activated. This helps reduce the error that occurs at the moments of high turbulence.

The most advanced are pulsed water meters, in which the reading counter mechanism in the form of an electric signal transmitted to the other device, often computerized. This scheme allows you to monitor the flow of water, even at a distance and connect them to the computerized accounting systems. At the moment, they are rarely used for personal use, but in the future will certainly come in handy for every apartment metering of water.

All the above types of water meters are used for both of cold and hot water for the bookkeeping. However, in the second case it is used more heat-resistant materials, in particular for the manufacture of the impellers and bearings. Metal thus must withstand temperatures up to 150 degrees Celsius, while the cold water meters are designed only to 40 degrees. According to the requirements of the State Standard, the minimum period of service of household water meters is 12 years. Mechanisms of cold water at the same time are checked every 5-6 years, and for the calculation of hot water - every 4 years.

electromagnetic counters

Apparatus such counters, which are also referred to as the magnetic induction, is quite difficult and is based on the well-known Faraday law. Electronic device unit calculates the electromotive force (EMF) of the induction, being in the electroconductive liquid. The magnetic field in this case is also created by an electromagnet, which is one of components of the counter. EMF becomes proportional to the flow rate, which allows to measure its speed and to calculate the water flow rate per unit time. The resulting information is converted into an electrical signal and either displayed on the display device, or transmitted to the computer. Such a system is, of course, costs a lot, so is mainly used in non-domestic purposes - in the food and water treatment industries.

Counters vortex type

It's not just water meters, is - flowmeters. They are used not only to take account of the amount of liquid, but also to account for the flow of steam and gases in the workplace. Such mechanisms recorded pressure fluctuations that occur in the flow surface of the inner flow mechanism substances. The more such differential pressures occur, the greater the volume of material passes through the meter. The data is converted into an analog or digital signal, and then transmitted to a computer.

Volumetric water meters

Another type of device, which has not yet gained popularity in our country. The essence of such a mechanism is the fact that here the water flow is measured portions. First, water under pressure is pumped into the section of the standard volume, then she rotates and skips dialed liquid further transmitting account information to the recorder via a gear transmission. Thus, during one revolution recorder section counts always the same amount of water consumed. Devices of this type are popular in the UK, and are used mainly in industrial plants, in particular where monitored weak water flow.

ultrasonic water meters

Technically complex devices, which are used exclusively in the industry related to wastewater treatment and water injection for enterprises. These flowmeters typically include in its composition two sensors, each of which sends an ultrasonic signal - one along the water flow, and the other - upstream. The system measures the speed of each of the signal and calculates a time difference. If the flow does not pass through the mechanism - the signals reach the sensor simultaneously. Thus calculated flow rate, and water flow is shown on the display.

Ultrasonic flow meters may be installed as a part of the outer tube and the inner. The first type is used when the measured flow rate of liquids with aggressive substances in the formulation. This helps to avoid direct contact of the device with chemicals and keeps running. Mortise sensors are installed inside the pipe and directly come into contact with the medium. They are often used in cases where the pipes are made of materials poorly conducting ultrasonic signal. However, their installation requires a certain time and engineering costs, while the outer sensors may be mounted directly in the manufacturing process without it stopping.

Differences between domestic and industrial water meters. Setting the counter to the water with his own hands

Counters household and industrial are similar in function, but differ significantly in design and size. Domestic water meters for typical diameter of 15-25 millimeters, whereas industrial flowmeters are put on pipe 25-400 mm in width. It should also be noted that for every apartment accounting typically used tachometric counters, which are placed separately in each dwelling. However obschedomovyh water system installed turbine and electromagnetic mechanisms whose diameter is from 50 to 200 millimeters.

Installation counter for domestic water type is rather complex procedure which is not suitable to carry out independently. Such an installation is at your own risk, as well as future repairs poorly installed equipment. In general, the presence of certain skills and tools to make it very real.

For installation you will need tools such as Bulgarian, spanners or wrenches, and a set of fittings and related water meters for hot and cold water. Before installing, you must determine what kind of place is "crashing" the counter. After that length of pipe is sawn grinder and formed on the edge cut thread. Designated pipe connection counter elements must be sealed by means fum ribbons or linen with a special lubricant. At the input to the meter is highly desirable to place the strainer excluding ingress of litter into the mechanism. The dial device is mounted so as to be clearly visible meter readings. Mounted meter inspected employee Deza and seal.

Choosing a water meter model for your home

At the moment, the Russian market of water meters is not exactly experiencing shortages. Along with the trend of increasing number of "budget" users is growing and the demand for such products. As has been described above, can now be found on the shelves of more than 500 types of flow meters of various types and designs belonging to different price ranges. Consider some of the most optimal in terms of price and reliability of the domestic models.

Counters CONSUMER cold and hot water VSKM 90-15

Universal product of domestic production, which is ideal to work with most domestic water supply systems. It may be attached to both the feed and return piping to measure the volume and network of drinking water. Working in cold and hot water, as well as in district heating systems. Operational temperature range devices ranges from 5 to 90 degrees Celsius. The pressure tap system should not exceed 1 MPa.

VSKM 90-15 refers to a type of the classic tachometer water meters. Water accounting is made by means of a rotating impeller, the number of revolutions is proportional to the flow rate of water flow in the pipeline. By design VSKM 90-15 -. "Dry" The counting mechanism is separated from the impeller by a sealed partition, and their interaction is carried out by magnetic action. This device also Multi - before moving to the impeller vane flow is divided into several jets, which allows to obtain more accurate data. "Dial" shows "run" of the device, in cubic meters and their shares. It is possible to transfer a remote electrical signal.

Appliance counter cold and hot water OSVH-25/25-OSVU

Another representative of the Russian manufacture. According to its characteristics in many respects similar to the previous model. Used in the feed, and in the reverse water supply and heating. Suitable for use in open and closed systems. Operational temperature range differs depending on the model: OSVH 25 is operated at a range of temperatures between 5 and 40 degrees celsius, whereas 25 stands OSVU from 5 to 90 degrees Celsius. pressure limit is the same for both versions - 1 MPa.

Like the previous model, the counter OSVH-25 / OSVU-25 -. "Dry" Counting mechanism is sealed and separated from the water flow partition. Interaction with the blades carried out by means of electromagnetic influence. The device has a high reliability and precision, making it quite popular among domestic flowmeters.

Counters CONSUMER cold and hot water Siemens WFK / WFW

More expensive and highly reliable water meters German production (Zenner, Minomess). Able to operate in any system heat and water from hot and cold water. They are particularly resistant to changes in pressure in the water network. Widely used for maintenance of residential buildings (private houses and apartments), as well as for use in public buildings and offices.

Siemens company are mechanical devices (tachometer). a counter mechanism is provided with protection from electromagnetic interference, which provides high accuracy. The scale reading at the same time - a convenient and visual.

The device can be installed both in vertical and in horizontal pipes. Plot "tapping" is not important - the water meter installation is possible both on a long straight stretch and immediately behind the "corner" of the pipe. Construction of segments subsequent to a counter, also not critical. Separately it is necessary to allocate a nice design models and the ability to connect remote transmitter signal. This is especially useful in offices and factories, where it is more convenient to keep records of water flow directly to the computer.

Summarizing

This article was a detailed explanation of the topic familiar to many, and many unknown devices known as water meters. Using this knowledge, you can easily choose the right meter for domestic and industrial needs, determine its design and type, as well as choose a specific model. And installation of such a device will help you save considerably on utility bills in the near future.

Installation water meter:

Step 1. As a rule, so looks like almost any cabinet in the bathroom, two risers and distributing them to the plumbing fixtures.

Step 2. For the installation of water meters and fittings require special tools: wrenches, Bulgarian, and so on.

Step 3. To embed the counters, you need to saw the pipe. Sawn pipe via grinder.

Step 4. Before installing the following example counters with transfer tube in place and determine which piece of pipe you need to cut.

Step 5. Be sure to seal plug connections. You can use the FUM tape, thread tango or linen with a special lubricant.

Step 6. At the entrance of the water meter, it is desirable to establish a mechanical strainer. He will eliminate the ingress of dirt into the appliance and prolong its service life.
