摘要： PURPOSE:To compensate an inertial force by detecting an amount corresponding to a component force in the main direction of the inertial force with a second sensor buried on a compensating body inserted into a portion inside a pipe which does not influence a Karman's vortex and detecting a specific amount by a first detector which is buried in a vortex generating body. CONSTITUTION:A vortex generating body 3 is inserted into a pipe while a longer base of an isosceles trapezoid in cross section is positioned on the upstream side, a compensating body 4 is inserted into a portion inside the pipe which does not influence a Karman's vortex of the vortex generating body 3, and its base of an isosceles triangle in cross section is made approximately equal in size to the longer base of the vortex generating body 3 and placed in parallel. The vortex generating body 3 is made to be functioned by a vertical alternating force perpendicular to an axial line due to the Karman's vortex and to a direction Q of flow while the compensating body 4 is functioned only by an inertial force, and ends of piezoelectric elements 5, 6 which are buried in the vortex generating body 3 and the compensating body 4 respectively are grounded in common while the other end of the element 5 is connected directly to a differential amplifier 12 and the other end of the element 6 is connected via an adjusting resistor 11 to the amplifier 12.

摘要： PURPOSE:To quickly replace a fluid of the inside of a housing by providing two cavities and two acoustic tubes on both sides of a vibrating body, and aggregating two acoustic tubes of the surface and the reverse side of the vibrating body and connecting them to one conduit tube. CONSTITUTION:By laminating housing 5, 6, a base body 1 and a vibrator 4 consisting of piezoelectric vibrators 2, 3, disk-like cavities 8, 9 having a roughly equal volume V are formed. Simultaneously, on both sides of projecting parts 1a, 1b of the base body 1, acoustic tubes 10a, 10b, 11a and 11b whose cross sections are semi-circular are formed, and their tips communicate with conduit tubes 12a, 12b formed by grooves 5d, 6d of the housings 5, 6. In this state, when the conduit tube 12b is set at the upstream side and inserted into a fluid, the fluid to be measured passes through the cavities 8, 9 from the acoustic tubes 10b, 11b and flows to the acoustic tubes 10a, 11a, and the fluid to be measured is always replaced.

摘要： PURPOSE:To obtain a transducer reduced in a measuring error over a wide flow speed range, by providing cavities and acoustic pipes both of which are almost equal in a dimension to both sides of a vibrator. CONSTITUTION:A mechanical-acoustic vibration system consisting of a vibrator 4, cavities 8, 9 and acoustic pipes 10, 11 is reduced to a drawing A when said system is represented by an equivalent electric circuit based on a mechanical system. Herein, Mn and Cm are mass and compliance of the vibrator 4 and M1 is the inertance of the acoustic pies 10, 11 and C1 is the acoustic capacity of the cavities 8, 9 and (a) is the coefficient determined by the plane area of the vibrator 4 and the cross-sectional areas of the acoustic pipes 10, 11. In this drawing A, by making the acoustic capacity of the cavities 8, 9 sufficiently small and making the resonance frequency of the acoustic system determined by the acoustic pipes 10, 11 sufficiently high, this system is made approximate by a drawing B and, as a result, the resonance frequency of this system is determined by the compliance of the vibrator 4, the mass of the vibrator 4 and the inertance of the acoustic pipes 10, 11. That is, when this resonance frequency is detected, the density of a fluid can be detected.

摘要： PURPOSE:To make it possible to measure the flow speed and the flow rate of fluid to be measured with high accuracy by fixing the end part of the first flange having the free surface to which a strain detecting element is attached to the second flange holding a vortex detecting body. CONSTITUTION:A first flange 31 has a free surface 31a as a diaphragm. The entire surface of a fixed end part 31b is welded and fixed to a second flange 21 in an airtight manner. Therefore, the contact of a strain detecting element 12 and a fluid to be detected can be prevented. An upstream-side columnar body 23 and a force receiving part 33 constitute a Karman generating body in a broad meaning. At this time, the bending moment with respect to the free surface 31a on the side of a balance weight 35 caused by inertial force when a vortex detecting body 3 receives external vibration and the bending moment caused by inertial force on the side of the force receiving part 33 have the same magnitude in the reverse directions in this constitution. Thus, the inertial bending moment with respect to the free surface 31a when the vortex detecting body 3 receives the external vibration can be cancelled.

摘要： PURPOSE:To compensate for the effect of external vibration at a low-cost, with a compact apparatus by operating first and second vortex generating bodies in association with the generation of Karman vortex, and offsetting bending movement of inertia associated with the first vortex generating body with respect to a flange place. CONSTITUTION:A columnar body 3 as a first vortex generating body and a columnar body 2e as a second vortex generating body display the vortex generating functions together. Since the length of the columnar body 3c is shorter than a columnar body in a conventional example, the force of Karman vortex and the inertial force caused by the external vibration are reduced. As a result, the bending moment Mo at the flange part 3a caused by the vortex force acting on the columnar body 3c becomes smaller than the moment in the conventional example. The bending moment of inertia Mu with respect to the flange part 3a based on the vibrations associated with a supporting post part 3b and the columnar body 3c and the bending moment of intertia Mv based on the vibration associated with the supporting post part 3b and a weight 3f have the different directions but have the same magnitudes, and the magnitude becomes smaller than that in the conventional example. The mass and the length of the weight 3f can be reduced by the reduced amount in length of the columnar body 3c so that the length is smaller than the diameter of a tube 1.
