Abstract

Apparat for å registrere bevegelses- og hastighetsprofil for masse, særlig flytende betong, som føres gjennom en rør- ledning (c) med radial symmetri. Det be- nyttes en ultralydsonde (l, 2) med en senderdel og en mottakerdel, og den ut- sendte ultralydstråle (r) sendes på skrå inn i rørledningen. Den reflekterte ultra- lydstråle (r1) fra massen omvandles i mot- takerdelen (2) og blir signalbehandlet i elektroniske kretser (3-10) for å presen- tere massens hastighetsprofil som funksjon av en avstand (d) målt på tvers inne i rørledningen (c). Ultralydfrekvensen er mellom 20 og 500 kHz, og de elektroniske kretser arbeider ved en samplingsf rekvens på 10-70 Hz. For å komme frem til en abso- lutt hastighetsprofil med separat fortegn separeres signalene fra de signalkompo- nenter som utledes av massens gjennom- strømning pr. tidsenhet.
