Zusammenfassung:	PURPOSE:To allow application for any kind of fluid with a simple handling along with higher measuring accuracy by a method the section of a measuring tube section is formed between upstream and downstream points of a pipe to be rectangular and a transducer is mounted on the external wall of a parallel surface. CONSTITUTION:A measuring liquid flows into a pipe 1 having a pipe wall 12. The upstream and downstream end parts of the pipe 11 are formed circular in section. A measuring tube section 15 is formed integral between the upstream and downstream end parts and the measuring tube section 15 has a section thereof formed rectangular. Transducers 20 and 21 comprise a piezo-electric vibrator, for instance and mounted on external walls of parallel surfaces 16 and 17 through a resin wedge. The transducers 20 and 21 are arranged in plurality so as to form a plurality of side lines 24. The achieves higher average effect on the surface as a whole thereby improving measuring accuracy.
