The meter of water is one of the most effective "legitimate" ways to reduce its costs for utility payments. Since this instrument allows you to pay for water used "in fact", which often turns out to be much less than the established standard. The main thing is to choose this most meter, what we will help you.
1
To begin with, decide how many meters you need, since the amount of cold and hot water used is calculated different devices. That is, you can purchase only one meter for cold water, two meters (for cold water and for a hot) or a universal device, which can cope with water at any temperature.
2
The following selection criterion is the type of power. Energy-dependent devices operate only in the presence of power and, accordingly, when it is not taken into account, it is already leading. More autonomous in this regard are non-volatile counters.
3
Regarding the principle of operation, you will have to choose from the following groups of devices: vortex, ultrasound, tachometric and electromagnetic. At the same time, as a household appliance, it is worth considering the last 2 types of the device.
4
Tachometric water meters have several advantages, thanks to which they have the greatest demand among users. These advantages include the compactness of the device, pricing access, reliability (can last more than a dozen years) and measurement accuracy.
5
Choosing a tachometric meter, pay attention to the basis of its design. It can be a wing (single-door or multi-line), turbine or combined. The main thing is that in this case you need to consider in this case, in addition to some operational features - the diameter of the pipes: the rooted devices are mounted on pipes not more than 40 mm in diameter, turbine - in the range of 50-200 mm.
6
Another moment relative to the tachometric meters of water - they can be "wet" and "dry" type. The first is less reliable because the counting mechanism in the water is due to the same (or rather pollution in it) starts to give malfunctions. Therefore, it is better to buy and install the filter to them. In the "dry" devices, this mechanism does not contact with water, so this counter serves longer. At the same time, it is also non-volatile and compact, but it is more expensive than "wet" and sensitive to magnetic fields.
7
Electromagnetic water meters are more accurate in measurements compared to tachometric and independent of water parameters (temperature, viscosity, density). But also, such devices have their own nuances: they "do not like" water with precipitation, but at the same time cannot function normally in absolutely clean water. In addition, electromagnetic counters can turn off during electricity interruptions, since it is treated with high-independent devices.
We gave you the main guides in choosing a meter for water, and more specific to your guidelines will give you a professional. Therefore, we advise before buying it is necessary to consult with a specialist in this profile.
