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.Apparatus for recording the movement and velocity profile of mass, especially liquid concrete, which is passed through a pipe (c) with radial symmetry. An ultrasonic probe (1,2) is used with a transmitter portion and a receiver portion, and the emitted ultrasound beam (s) is transmitted obliquely into the pipeline. The reflected ultrasonic beam (r1) from the mass is converted into the receiver part (2) and is signal processed in electronic circuits (3-10) to present the velocity profile of the mass as a function of a distance (d) measured across the pipeline. (c). The ultrasonic frequency is between 20 and 500 kHz, and the electronic circuits operate at a sampling frequency of 10-70 Hz. In order to arrive at an absolute speed profile with a separate sign, the signals are separated from the signal components derived from the mass flow rate per minute. unit time.
