Number of nozzles

The number of individual nozzles (nozzles) provided for in the design of the sprinkler. This number corresponds to the number of jets that the device is capable of delivering at the same time.

Theoretically, the more jets, the thinner they are and the more evenly the water is sprayed. However, in fact, this indicator by itself has practically no effect on irrigation efficiency: for example, a single nozzle of a properly selected design may not be inferior in efficiency to a set of several nozzles. Therefore, when choosing, it is worth focus not so much on the number of nozzles, but on other practical characteristics and features of the jet (the latter can be clarified, for example, from video reviews). We only note that oscillating sprinklers(see "Type"), by definition, are equipped with a set of several nozzles (up to 25 – 28).

Spraying width

The irrigation width provided by the sprinkler, to be more precise, the width of the area covered by the device at a time, without turning the nozzles horizontally.

This parameter is relevant primarily for oscillating models (see "Type") — they evenly capture a rectangular space, and the width is one of the main dimensions for a rectangle. In other types of sprinklers, we are talking about the width of the jet at maximum range (because the jet expands as it moves away from the nozzle); however, for such models, it is more convenient to indicate the size of the captured space by the angle of irrigation (see above), and the width for them is rarely indicated.

Сoverage distance

The maximum range that the sprinkler can provide.

The choice for this parameter depends primarily on the size of the area to be covered. However, keep in mind that a high range usually requires fairly high pressure and can degrade watering efficiency close to the nozzles. Therefore, even in large areas, it is sometimes more convenient to use a system of several sprinklers with a short range, rather than a long-range device.

Max. coverage area

The largest area that the sprinkler can cover during operation (or the standard coverage area for models that do not allow changing the size of the captured area).

The larger the area, the more watering area it may require. At the same time, the irrigation system must correspond not only to the area, but also to the shape of the site. Therefore, a model covering a large area is not always the best choice — sometimes (especially in areas of complex shape) it is easier to cover the required space with a few relatively modest sprinklers.

In some cases, knowing the irrigation area, you can determine other characteristics of the device: for example, for a sprinkler with an irrigation angle of 360 °, you can calculate the maximum range without much difficulty, even if it is not indicated in the characteristics.

Pressure

The pressure of the water in the connected hose/pipe that the sprinkler is designed to handle: lower pressure will not give the device the required performance, higher pressure may cause damage. And even if too high pressure did not lead to an "accident" immediately, it can happen at any time. Therefore, this parameter should never be ignored.

The best option is considered to be the situation when the pressure in the hose is slightly (by 0.4 — 0.5 bar) does not reach the claimed maximum — this allows you to fully realize all the capabilities of the sprinkler and at the same time gives a guarantee against breakage in case of pressure surges.
