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.
Minimum coverage area
The smallest area that a sprinkler can cover in normal operation, in other words, the area captured at a minimum range.
The minimum area is indicated only for models in which the size of the watered area can be adjusted (for example, by changing the angle). The smaller it is (at the same maximum), the wider the adjustment range. It also measures the suitability of a sprinkler for an area that is significantly smaller than the maximum irrigation area (see below). At the same time, when choosing, do not forget that models with the same area may differ in the shape of the space covered, the irrigation angle, etc.
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.
