Abstract

Ultrasonic gas/liquid flow meter with a W-shaped path inside the tube. The two transducers (101, 102; 201, 202) are offset axially from the execution of known geometry with a W-shaped measurement section and/or are set at an angle such that the transducers and the W-shaped path are not situated orthogonally in relation to each other.
