Abstract: The invention relates to a method for testing fuel element tubes by ultrasonic energy. For testing, each tube becomes disposed in the space between a transmit transducer and a receive transducer. The echo signals falling within a predetermined time interval are evaluated. Since the distance between the transducers may vary as the transducers move through the space between fuel element tubes, the transmitted signal reaching the receive transducer without passing through the tube may be confused with the revolving echo signal. Therefore, this invention discloses an arrangement for cyclically controlling the setting of the time gate before each such tube is in position between the transducers. To this end, the ultrasonic transit time of signals between the transmit transducer and the receive transducer is measured in the gap between the last tested tube and the next to be tested tube. A constant value is subtracted from the measured transit time value and this constant value is selected so that the transmitted signal received during the transit time measurement falls just outside the gated time interval.

Abstract: Der als Durchflußmesser verwendete Wirbelzähler ist mit einem stabartigen Wirbelkörper (7) versehen, von dem sich während der Durchströmung der Rohrleitung abwechselnd Karmanwirbel ablösen, deren Frequenz von einem elektrischen Fühlelement (18) erfaßt wird. Das Fühlelement (18) sitzt in einem Halter (17), der in die Signalleitung (12) eintaucht. Der Wirbelkörper (7) ist in einem in das Zählergehäuse (1) einschiebbaren Rohreinsatz (6) eingebaut und die Signalleitung (12) ist als ein in die Wandung (11) des Rohreinsatzes (6) eingebrachter Kreisbogenkanal ausgebildet, der die beiden Anbohrungen (9, 10) miteinander verbindet, welche die Wandung (11) beiderseits des Wirbelkörpers (7) zum Rohrinnern hin durchbrechen. Das Zählergehäuse (1) trägt eine in die Mitte des Kreisbogenkanals (12) einmündende Radialbohrung (16), in die der Halter (17) mit dem Fühlelement (18) eingesetzt ist. Durch die besondere Ausbildung des Kreisbogenkanals (12) mit den Anbohrungen (9, 10) und dem speziellen Einbau des Fühlelements (18) ergibt sich ein einfacher Zähleraufbau und die Signalleitung ist besonders kurz, so daß die Strömung hierin auch noch bei kleinen Zählernennweiten mit großer Signalintensität pulsieren kann.
