[4] [5] [6] Since then the popularity of these highly uniform yet low application sprinklers has caused every major sprinkler manufacturer to produce their own version of an MPR sprinkler, including Rain Bird [7] and Toro.
For example, the typical professional controller will calculate the actual flow rate running in the system when a specific zone is operated, compare this to a pre-configured required amount, and adjust the irrigation process if deviation from the zone's flow rate is detected; This mechanism is called "Flow monitoring", and can prevent ...

Spray nozzles can for example be fire sprinklers or water mist nozzles, hose reel nozzles, water monitors and deluge fire system nozzles. Calculation
Soil type and root horizon may nullify the need for high DUlq sprinklers. Low sprinkler DUlq does not guarantee inefficiency, nor does high DUlq guarantee efficiency. An alternative is Christiansen's uniformity coefficient (CU), defined as the average depth of irrigation water applied minus the average absolute deviation from this depth, all ...
