Installation water meter - a good option to save the family budget, but the life of the subject is three, four years.After the expiry of this period should be removed to check the water meter or just replace it.For this purpose it is necessary to obtain information about how to remove the water meter, so no problems with utilities.

counter functioning water
In order to better understand the water meter, you must familiarize yourself with a complete set of the device.
system configuration for water meter consists of:
- locking ball valve;
- return valve;
- set podsoediniteley.
shut-off valve is responsible for the overlap of the water supply.The main function is to clean the strainer from t
Varieties water meters
Among a variety of counters for water meters for water release:
- the single-type pipes, which have a diameter of 1 to 2.5 cm;
- multi-jet type for pipe diameters from 1.5 to 5.0 cm;
- valve types;
- turbine type.
The single-jet water meters, the volume of water consumed depends on the rotation of the impeller, which rotates during the flow of water through the pipeline.Magnetic couplings help to fix the number of revolutions.These counters have reliable protection against ingress of water and long life.Advantages of single-jet meters: Installation pulsed output and protection against external magnetic field.
reduced flow turbulence characterized by a multi-jet water meter type.The stream of water, before getting to the impeller meter is distributed to multiple streams.Advantages: easy assembly and disassembly, remote reading.
Valve water meters work as well as multi-jet, the main difference is the presence of the valve to turn off the water.Advantages: additional installation of pulse output, ease of rotation of the counter in different directions.
turbine meter comprises a basic element - the multiple-screw that fulfilling momentum, measures the amount of water.Indications turbine meter regulated by a screw which is located in the housing.Advantages: Low pressure loss, and installation for hot and cold water systems.
Depending on the operating principle of the release:
- water meters mechanical;
- electromagnetic type;
- ultrasonic type;
- superstaticheskogo type.
counter for mechanical type of water works on the principle of energy consumption of water that passes through the filter and the rotating impeller.
Faraday's law - the basis of the work of an electromagnetic water meter.The water that flows through the meter under the influence of the magnet is converted into an electrodynamic force which the device needs to water flow units.
ultrasonic operating principle is based on passing a counter flow of water and measuring the ultrasonic vibrations.Calculator water level fluctuations and writes data thus measures the flow of water.
resonant or superstatichesky meter for water flow meter has a specific section, which is divided into three parts: the main and two side.These channels are interconnected at the inlet and at the outlet portion of the flow meter.The main channel is equipped creator thread that sends a stream in the other two channels.
number of changes in the input channels to attain to the level of water consumption of water through the meter.
Depending on the volatility release:
- water meters, electric;
- mechanical water meters.
In connection with the consumption of water is isolated:
- meters for hot water, which are different markings on the back of up to + 130 ° C;
- counters for cold water - with markings to + 40 ° C.
Videlyayut counters for water:
Wet counters have additional insulation from the water, have a high resistance to moisture.These meters are more popular than dry.Dry counters have an impeller which is in the water, and the counter is isolated from the water supply, the calculation of water passed through the magnetic mechanism.
Short circuit replacing the counter to check
Every three years, it is necessary to remove the meter to verify that.Before that, you must take a number of actions:
1. Call or go to the controller to get "designed to test the meter for the water."After receiving the document, during the absence of the counter, charging for the use of water will be produced at an average rate.
2. Remove the meter for water.In place of the counter, you must insert a special metered piece of pipe, which at both ends has a thread.
3. Turn the counter to check in the "Water".
4. Get the counter after checking and replace.
5. Call the supervisor, for sealing the counter.If the seal is not installed, the water charges will be made according to the requirement of public utilities.
Removing water meter alone
- silicone or rubber gaskets.
recommendations on how to remove the water meter:
1. First turn off the water.To do this, use the crane on the inlet pipe.If the valve is not, contact the municipal service of a statement of overlapping water and specify a time when it can be done.
2. After the overlap of water, using an adjustable wrench, unscrew the nuts on both sides of the counter.Use the lighter if the nut with a wrench to unscrew the impossible.
3. Clean the fitting from corrosion and plaque from the residue of old gaskets.To do this, use a cloth dampened with a mixture of anti-corrosion, and wait for half an hour, and then with a conventional sponge, wipe the nozzle.
4. To prevent possible penetration of rust in the coarse filter must be cleaned and this mechanism.For this filter remove the wrench and make cleaning or replacing the grid, depending on the amount of dirt.
5. The next step - replacement pads.When replacing a meter of water used three types of pads: rubber, silicone, or paratinovye.The best option - silicone gaskets that eventually do not lose elasticity and do not leak.If you use rubber gaskets or paratinovyh desirable to wind the thread flax or special tape.
6. Install the counter.When installing pay attention to the arrow that shows the flow of water.Do not confuse the input side and the output water.
7. When the counter is set to begin tightening the screws.First, do it by hand, until it stops.Then, using a wrench tighten the nut one and a half turns.After turning on the water at the junction of the pipe with the counter should not be any leaks.
8. In the event of a successful replacement of the meter, call the municipal service representative to install seals and marks on the data sheet.
tips on installing and removing the water meter
- if you unscrew the nut with a pipe wrench can not be - they need to anneal gas, then all the connections you need to repack;
- minimum air temperature in the room where installed water meters + 5 ° C;
- when installing the counter on the street or in a basement need to take care of additional insulation of pipes;
- if the hot water flows into the room through the two pipes, the installation of water meter must be installed throughput valve on the circulation pipe, if you do not install the valve, the meter will show an increase in the flow rate of water;
- if a fire make sure the installation of drainage valves, which also need to be sealed, to install the valve to invite a representative of the fire department;
- nuts always unwind clockwise;
- fittings must be cleaned of old gaskets before installing the new ones;
- asbestos fabric gaskets are not suitable for the installation of water meters, the best option - or a silicone rubber;
- when replacing the meter is desirable to clean the coarse filter water: with a key, remove the filter and replace or clean the mesh;
- use the fittings are made of brass;
- before installing a new water meter is recommended to test the device in a special test and measurement service, for it to show your new counter to the technical passport;
- procedure before removing the meter notify utilities and controller, which serves the plot;
- after mounting counter invite controller to set the seal;
- If you have trouble installing or removing a water meter contact special services;
- when choosing a place for the meter is recommended to install the counter at the entrance to the indoor plumbing.
Installation malfunction counter water
1. If you have poor water pressure in the room, try to clean the filter.Do not clean the filter yourself, it is better to apply to the special services and experts will carry out the procedure.By law filter cleaning - free process.
2. In case of accidental failure of the seals should immediately contact the utilities.Pereplombirovanie - paid procedure, but the cost of this process is much less than the penalty for the broken seal of the inspector.
3. If you suspect a malfunction or counter readings in excess of the actual flow rate, an unscheduled inspection of the meter is not paid.
4. If the meter needs to be replaced leak gasket.
5. When under-meter readings necessary to examine the unit for debris and other foreign objects.
