4.2.2 MICRO-SPRINKLERS Micro-sprinklers are often incorrectly referred to as “Micro-jets”. The latter is a brand name for a certain type of micro-sprinkler. Micro-sprinklers have much lower discharge rates, compared to overhead sprinklers. Their discharge rates can vary from ca. 30 to 80  /h. Micro-sprinklers can be divided into two broad groups, i.e. those with static nozzles (Fig. 4.10) and ones with spinning or rotating nozzles (Fig. 4.11). Micro-sprinklers with self-cleaning, wobbling heads are also available (Fig. 4.12).
