Abstract: A measurement control section of a flow meter device causes a measurement block dividing section to divide a sampling cycle Tc into three or more, for example, four measurement blocks Tb of an equal length and causes the flow measuring section to measure the flow of a fluid in each of the measurement blocks Tb. A flow calculating section of the flow measuring section calculates an average value of flow values obtained in all of the measurement blocks in each sampling cycle Tc, as a flow value in each sampling cycle Tc. This configuration allows a flow meter device which employs an inverse transit time difference method, such as an estimation gas meter, to more effectively lessen the influence of a pulsation and to perform flow measurement with higher accuracy.

Abstract: 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.

Abstract: A setting method of a flow meter device comprises (A) measuring a compensation coefficient in a case where a fluid is flowed with a flow within a predetermined range, and deriving a first function representing as a linear function a relationship between a measurement compensation coefficient which is the measured compensation coefficient and a conversion value which is obtained by converting a set flow which is the flow of the flowed fluid, using a predetermined function; (B) setting a reference flow which is an arbitrary flow within the predetermined range and calculating a reference compensation coefficient which is a compensation coefficient corresponding to the reference flow based on the reference flow and the first function; and (C) storing the reference flow and the reference compensation coefficient corresponding to the reference flow.
