Strain gauges A, B for a bending portion cross each other and are stuck to a strain gauge sticking portion 7 for a bending portion located in a portion applying centrifugal force or centripetal force of a fluid thereto in a bending portion 4 in a bending circular tube 1 formed by bending a tube circulating the fluid therein. Further, strain gauges C, D for compensating static pressure and temperature cross each other and are stuck to a strain gauge sticking portion 11 for a straight tube portion located in a straight tube portion 8 connected to the bending portion 4 in the bending circular tube 1 . Detecting signals of strain gauges A, B for a bending portion and strain gauges C, D for compensation are guided to an opposite position of a bridge circuit 12.
