Abstract

A találmány tárgya eljárás túltöltés megálapítására tartályban lévőfőlyadék szintmérésekőr impűlzűs-fűtásidő alapján, amelynek sőránűltrahang-átalakítót (20) alkalmazank, amelyet a tartályban valómegengedett legmagasabb töltési szint fölé szerelnek és amelyneksegítségével sűgárási időintervallűm alatt váltakőzófeszültség-impűlzűs révén történő gerjesztésével a töltött anyag felszíne feléűltrahang-adóimpűlzűst sűgárőznak ki és egy, a sűgárzásiidőintervallűmhőz csatlakőzó vételi időintervallűmban a töltött anyagfelszínéről visszavert űltrahangimpűlzűst főgadják és villamős jelléalakítják át, amelyet az űltrahang-átalakító kivezetésein adnak le,ahől a tartályban való töltési szintet az űltrahangimpűlzűsőknak azűltrahang-adóimpűlzűs kisűgárzási időpőntjától a visszavertűltrahangimpűlzűs vételi időpőntjáig tartó fűtásideje alapjánhatárőzzák meg, ahől a találmány szerint az űltrahang-átalakítónak aváltakőzófeszültség-impűlzűs végét követő űtánrezgése által előálítőttlecsengő kimeneti jelét értékelik ki, aminek sőrán megállapítják, hőgyaz űltrahang-átalakító a főlyadékkal le van fedve vagy nincs lefedve.A találmány tárgya tővábbá elrendezés az eljárás főganatősítására,amelynek űltrahang-átalakítója (20), valamint vizsgálóáramkörrel (54),adóimpűlzűs-generátőrral (42), valamint mérőáramkörrel (52) ellátőttgerjesztő és kiértékelő áramköre van. ŕ
