Abstract

Sono descritti un metodo e un dispositivo per controllare la portata di un fluido per azionare una turbina, il fluido passando attraverso un percorso di palette di turbina tra un'entrata e un'uscita di fluido, consistente nel: percepire il valore della pressione del fluido in corrispondenza dell'entrata e dell'uscita di fluido; calcolare elettronicamente la portata di fluido sulla base dei valori di pressione percepiti: confrontare elettronicamente la portata calcolata con una portata massima voluta; e fornire automaticamente una indicazione di quando la portata calcolata supera la portata voluta massima.
