摘要： 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.

摘要： A gas meter apparatus (1) of the present invention comprises a flow measuring device (5) which measures a gas flow; a measurement value calculating section (21) and a liquid crystal display section (2) 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 (21) determines that the integrated value has reached 1 liter, it informs a light emission commanding section (22) of determination result. In response to this information, the light emission commanding section (22) causes a LED light emitting section (3) to emit light toward a sensor (7). Therefore, the gas meter apparatus (1) 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 14 compares a flow rate calculated by a flow rate calculation means 11 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 13 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.摘要翻译： 当流量等于或大于参考流量时，参考电压被改变为能够稳定测量的水平，由此实现在大流量时的测量精度的提高。 流量确定装置14将由流量计算装置11计算的流量与参考流量进行比较。 在计算出的流量比基准流量大的情况下，由基准电压设定单元13设定的基准电压发生变化，能够稳定地检测零交叉点， 接收信号的幅度很小。 因此，即使在流量大的情况下流体流动受到干扰的情况下，也能够提供能够以高精度稳定地测量流量的流量测量装置。

摘要： In a flow meter device of the present invention, a time measuring section of the flow meter device includes a first counter which starts counting at a starting point of measurement of propagation time; and a second counter which starts counting at an end point of the measurement of the propagation time, and performs counting at a higher speed than the first counter. A propagation time TO is finally obtained by subtracting time Δt which is measured by the second counter and passes from the end point until the first counter counts up, from time T which is measured by the first counter and passes from a starting point until the first counter counts up after the end point. A flow calculating section calculates a flow with high accuracy using the propagation time TO. Thus, lower electric power consumption can be achieved, and accuracy of measurement of flow can be improved.

摘要： In a flow meter device of the present invention, a unit measuring step is defined as a procedure for measuring ultrasonic sound wave propagation times by changing the direction in which an ultrasonic sound wave is transmitted and received between a first transducer (2) and a second transducer (3), and a time measuring means (12) measures a propagation time in a forward direction and a propagation time in a reverse direction in a unit measuring step. A time difference detecting means (16) detects a difference between the propagation time in the forward direction and the propagation time in the reverse direction which are measured by the time measuring means (12). A determiner means (17) determines whether or not there is a fluid flow based on the time difference. According to presence/absence of a fluid flow, the number of times the unit measuring step is performed is determined. Therefore, it can be determined whether or not there is a fluid flow quickly in real time. A responsiveness can be improved such that a measuring method can be switched to correspond to presence/absence of a fluid flow.
