摘要： A multilayer flow path member of an ultrasonic fluid measurement apparatus and an ultrasonic fluid measurement apparatus capable of enhancing the measurement accuracy of the mean flow velocity are provided. When a multilayer flow path member 30 placed in a measurement flow path 14a shaped in a rectangular cross-section pipe of an ultrasonic fluid measurement apparatus 10 is partitioned into a plurality of flat flow paths 14e by partition plates 32 attached to a frame 31 along a flowing direction, the partition plates 32 are provided so as to face inner faces 15f and 17a of the measurement flow path 14a. Thus, the partition plates 32 are exposed and face the inner faces 15f and 17a of the measurement flow path 14a and thus the space between the exposed partition plate 32 and the inner face 15f, 17a of the measurement flow path 14a becomes the highest-stage or lowest-stage flat flow path 14e. Therefore, a problem of degrading the measurement accuracy as a fluid flows into the space between the frame 31 forming a part of the multilayer flow path member 30 and the inner face 15f, 17a of the measurement flow path 14a as before does not occur and accordingly the measurement accuracy can be enhanced.

摘要： For the purpose of solving the above problems, the present invention includes: transmission/reception means provided in a flow path for performing transmission/reception using a state change of fluid; repetition means for repeating the transmission/reception; time measurement means for measuring a time of propagation repeated by the repetition means; flow rate detection means for detecting a flow rate based on a value of the time measurement means; and number-of-times change means for changing to a predetermined number of repetition times. With such a structure, an influence caused by a variation of a flow can be suppressed by changing the number of repetition times so as to be suitable for a variation. As a result, reliable flow rate measurement with a high accuracy can be achieved.

摘要： The present invention provides an ultrasonic transducer having uniform characteristics. Because the characteristics of a pair of ultrasonic transducer are equalized with each other, measuring accuracy of an ultrasonic flowmeter can be improved. Electrical connection from an electrode surface 13 of a piezoelectric body 11 to an external electrode is achieved not by soldering but by an electroconductive elastic body 16. As a result, variations of the frequency characteristics due to thermal load on the piezoelectric body 11 can be reduced, and this makes it possible to obtain an ultrasonic transducer with uniform characteristics, and measuring accuracy of an ultrasonic flowmeter using a pair of the ultrasonic transducer can be improved.

摘要： An ultrasonic flowmeter includes a flow path defined by four wall sections, a flow measurement section, a calculation section and a pair of ultrasonic oscillators for transmitting and receiving an ultrasonic wave over a distance. The flow path is configured to reduce the influence of a phase difference, which results from the varying propagation distances of a direct wave and a reflected wave, by changing one or more of the flow measurement section configuration, the ultrasonic wave frequency, the orientation of the ultrasonic oscillators, and the distance between the pair of ultrasonic oscillators. A measurement section is suitably configured to measure the propagation time of the ultrasonic wave propagating between the pair of ultrasonic oscillators. Additionally, a calculation section is suitably configured to receive measurements from the measurement section and to calculate the fluid flow in the flow measurement section.

摘要： Provided are an acoustic matching member with a fixed density, an ultrasonic transmitter/receiver unit with a high sensitivity, and an ultrasonic flow meter device which attains stable and high-accurate flow measurement. An acoustic matching member comprises hollow elements and a binding agent. The acoustic matching member is created by removing hollow elements having higher densities, hollow elements having cracks, etc., from hollow elements before sorting-out. Since the hollow elements having higher densities, the hollow elements having cracks, etc., are removed from hollow elements before sorting-out, it becomes possible to provide an acoustic matching member having fixed characteristics without being affected by a manufacturing lot and a transportation process of the hollow elements. An ultrasonic transmitter/receiver unit created using the acoustic matching member has fixed characteristics and is able to perform high-accurate flow measurement.
