The new constant pressure controlle r for irrigation system is used to control the terminal pressure ( at the terminals of the branch pipes ) , and it can more effectively convert the frequencies of the moters . thus energy can be saved 新型的恒壓噴灌控制器采用的是末端控制(即分干管末端) ,這種控制方式可使噴頭獲得更好的噴水壓力,并且使電機可進行更有效的調(diào)速,從而獲得更好的節(jié)能效果。
