method and device for measuring laufzeitdifferenzen of ultraschallimpulsen for determination of flow fields

摘要

a method and a device for measuring laufzeitdifferenzen of ultraschallimpulsen for determination of flow fields, in particular components in gaseous media, used in a variety of ultraschallsendern and a receiver of ultrasonic pulses so as a downstream register and aufnahmeeinheit.in the subject range without contact and without disturbing laufzeitdifferenzen of ultraschallimpulsen probes to measure, and the measuring range without influencing the flow to choose as a receiver for the ultrasonic pulses to one or more laser beams used d ie in the crossroads with the ultraschallimpuls be modulated and the modulation to be registered.
