摘要： An objective of the invention is to provide a multilayered flow passage member that enhances fluid measurement accuracy of an ultrasonic fluid measurement apparatus and an ultrasonic fluid measurement apparatus using the multilayered flow passage member. When fusible projections 20 are fused by a heating head 21 while partition plates 11 are inserted into side plates 13 and 14, a fused state provided by the heating head 21 changes according to either side of each of the partition plates 11, because fuse surfaces at leading ends of the respective fusible projections 20 are sloped in the vertical direction. An outermost end of each of fusible projections 25 that first contacts the heating head 21 is first fused. During a course of the fusible projections 25 being fused toward their roots, the partition plates 11 are pressed against ends of respective insert holes 17a that are on the opposite side of the outermost ends that are first fused. As a result, the partition plates 11 become one-sided with respect to the respective insert holes 17a and fixed by means of positional accuracy of the insert holes 17a. Even when clearance exists between the partition plates 11 and the insert holes 17a, the partition plates can be fused with superior accuracy.

摘要： A gas meter apparatus of the present invention comprises a flow measuring device which measures a gas flow; a measurement value calculating section and a liquid crystal display section which are configured to calculate an integrated value of the measured gas flow and electrically display the integrated value. Every time the measurement value calculating section determines that the integrated value has reached 1 liter, it informs a light emission commanding section of determination result. In response to this information, the light emission commanding section causes a LED light emitting section to emit light toward a sensor. Therefore, the gas meter apparatus is able to conduct a test by a test method in which a change in the displayed integrated value of the gas flow can be known from reflected light of emitted light, even when the integrated value of the gas flow is displayed in a digital form.

摘要： When a flow rate is equal to or more than a reference flow rate, a reference voltage is changed to a level capable of measuring stably to thereby realize the improvement of measurement accuracy at the time of a large amount of flow rate. A flow rate determination means compares a flow rate calculated by a flow rate calculation means with the reference flow rate. When the calculated flow rate is larger than the reference flow rate, the reference voltage set by a reference voltage setting means is changed, whereby the zero cross point can be detected stably at the portion where the degree of the influence of the change in the amplitude of the received signal is small. Thus, it is possible to provide a flow rate measuring device capable of measuring a flow rate stably with high accuracy even when a fluid flow is disturbed due to a large amount of flow rate.
