Title (DE) DURCHFLUSSMESSER UND MESSKANAL
(EN) FLOW METER AND MEASURING CHANNEL
(FR) DÉBITMÈTRE ET CANAL DE MESURE
Abstract:
(DE) Offenbart ist ein Durchflussmesser mit zumindest zwei zu einander beabstandeten Mess-Sensoren, vorzugsweise Ultraschall-Sensoren, wobei die Ein-und Auskopplung der Messsignale in bzw. aus einem Fluid über ein Koppelstück erfolgt, das in eine Umfangswandung eines durch Hydroforming hergestellten Messkanals eingesetzt ist. Alternativ kann die Ein-und Auskopplung der Messsignale auch durch eine Wandung des Messkanals hindurch erfolgen.
(EN) The invention relates to a flow meter with at least two spaced-apart measuring sensors, preferably ultrasonic sensors, wherein the coupling in and out of the measurement signals in or out of a fluid occurs via a coupling part which is inserted into a circumferential wall of a measuring channel produced via hydroforming. Alternatively, the coupling in and out of the measurement signals can also occur through a wall of the measuring channel.
(FR) La présente invention concerne un débitmètre comprenant au moins deux capteurs de mesure espacés entre eux, de préférence des capteurs à ultrasons, l’injection de signaux de mesure dans un fluide ou leur extraction du fluide s’effectuant par l'intermédiaire d’une pièce d’injection/extraction qui est insérée dans la paroi circonférentielle d’un canal de mesure réalisé par hydroformage. En variante, l’injection et extraction des signaux de mesure peut aussi être effectuée à travers une paroi du canal de mesure.
