La presente Norma si applica ai sensori di portata di un gas, un liquido o un solido granulare. Tali sensori modificano il proprio stato di uscita in caso di superamento di un valore preimpostato di velocità del flusso. Tali sensori di portata sono autonomi, con elementi di manovra a semiconduttore destinati a circuiti con tensione nominale non superiora a 250 V c.a. o 300 V c.c.
La presente Norma non si applica a dispositivi con uscite analogiche.
Questa Norma viene pubblicata dal CEI nella sola lingua inglese in quanto particolarmente mirata a settori specialistici.
La presente Norma recepisce il testo originale inglese della Pubblicazione IEC e pertanto consta delle sole pagine dispari.
