ULTRASONIC TRANSDUCER ARRANGEMENT FOR A CLAMP-ON ULTRASONIC FLOW MEASURING POINT AND A CLAMP-ON ULTRASONIC FLOW MEASURING POINT AND METHOD FOR PUTTING THE CLAMP-ON ULTRASONIC FLOW MEASURING POINT INTO OPERATION

摘要

The invention relates to an ultrasonic transducer arrangement (10) for a clamp-on ultrasonic flow measuring point (1) comprising: multiple ultrasonic transducers (20), said ultrasonic transducers being designed to emit ultrasonic signals into the measuring tube and/or to receive ultrasonic signals from the measuring tube, a first group of first ultrasonic transducers (G1) being located on a first side (2.11) of the measuring tube and a second group (G2) of second ultrasonic transducers being located on a second side (2.12), opposite the first side, of the measuring tube, wherein at least one first/second ultrasonic transducer is designed to receive ultrasonic signals of at least one first/second ultrasonic transducer, characterised in that neighbouring ultrasonic transducers of the first group are interspaced by first distances (A1) and neighbouring ultrasonic transducers of the second group are interspaced by second distances (A2), the first distance and the second distance being different, where 2*A1 = A2 = 1.125*A1, and in particular 1.75*A1 = A2 = 1.16*A1, and preferably 1.6*A1 = A2 = 1.25*A1.
