How to choose a water meter for the apartment - practical tips

feasibility of using this device in the home account proven practices.Those who have already put water meters, can confirm that the amount of water payment declined 3 - 3.5 times.Given the low cost of water meters, expenses for their purchase and installation recouped fairly quickly.

way, the primary setting of such a device is performed Criminal forces for free.If it starts a conversation Representative payment services, it is a clear violation of the law.It is immediately necessary to remind this zealous public utilities.

, you should find out, and from what and how, in fact, choose water meters before to deal with the acquisition of the device?Is there any difference between the available models in the sale?Stop on the design of existing and their operation principle, we will not - it's very few people interested (and understandable).We consider only the particular instruments and how they affect their practical application.

Classification counters

By type of resource

All models are designed for installation in concrete "thread."Some - only for cold-water systems, others - DHW.For information about installing, we wrote here.

What to consider: devices for hot water and can be mounted on the pipe with the cold, because they operate at temperatures up to 130 ° C.But put on the HVS model for DHW can not - more than 40 ° C, they do not survive.

nutrition

There are devices that plug into an electrical outlet.Of course, these models come with a variety of additional features, they are more convenient and perfect.But whether they are suitable for our conditions?It is not only in constant problems with CNN / supply, especially in rural areas, and even in the winter.Voltage Quality - this is another reason that makes think twice before spending money on such models.

on realized engineering decision

There are several types of counters.For everyday use, you must choose tachometer model .Simpler and cheaper - single-jet and multi-jet.To calculate the water flow to establish more complex device (for example, a gate) is irrational.

What to consider:

• if mains water quality is poor, it is necessary to choose the multi-jet meter;
• devices with impeller mounted on a "thread" with a diameter less than 40 mm.For larger pipes must be purchased turbine model;
• under considerable pressure drops and regular best option - a combined counter (turbine + impeller).

What to look

first - on Calibration period .All the rest - it is then.Any checker necessarily subject to periodic monitoring for compliance with the accuracy of its measurements at a given time parameters, stated by the manufacturer.This is understandable, since any mechanism eventually wear out.Details of Calibration period is required to be displayed in the technical documentation on the counter - in a table or in the text of the passport, instruction manual.And what it is, the better.

second - on date of manufacture.It is understood that the instrument - it is not food.But the first calibration measurement accuracy it passes by the manufacturer.It is from this date (corresponding mark is in the passport) and begins the countdown to the next control parameters.And if the counter for some reason, for a long time lying somewhere in the warehouses?And as time went on.

Those who neglect this often have to deal with product verification the very next year.And what is it?You need to call a locksmith - cut off the water - to dismantle the device.But the water is something you need every day.So instead of this counter should be temporarily set or a device called a "simulator" or culled device.Someone in the house there is something like that, and he will be able to do without the services of the Criminal representative?

Next - a drive in the SSC in fact, and there is, as always, all.And after receiving the certificate and the product to checking - in reverse order.If we add to this that in the time between removing and reinstalling "their" counter charge for water consumption will be charged according to the norm, and specialist services will also have to pay for, such a figure as the date of manufacture of the device, requires urgent attention.

If the first two criteria appropriate counter, it is necessary to pay attention to the following parameters:

• mounting dimensions.Perhaps a mismatch diameter of the flange and the pipe will have to purchase additional adapters;
• the maximum pressure in the system;
• have quality certificate.

All other parameters layman hardly say anything.

Tips professional

• Before engaging meter verification, you need to pick up a calculator and calculate everything carefully.The cost of the device is known.It remains to determine how much money (not to mention the time), subject to the foregoing, it is necessary to spend for verification.At the same time, few people take into consideration that it will have to deal with every year, as even those in the control / status at the factory working life (on the act) - not more than 1 year.Consequently, after 12 months - all over again "in a circle."

Experience shows that simple models of water meters calibrate it makes no sense.Much cheaper (considering all the trouble and expense) to buy a new device, and by calling a locksmith to replace with the preparation of the relevant act.And then a few years to forget about this problem.Given that the price of such models (for example, "Betar") ranges from 700 to 2 500 rubles , the savings is obvious.

• worked to counter all the declared service life, it is necessary to install it on the pipe water filter.
