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.

摘要： In a flow meter device of the present invention, a control means causes a temperature measuring means to singly measure a temperature of a fluid. A flow compensation means calculates a temperature of a fluid from a propagation time and makes compensation for the flow rate using the temperature calculated based on the propagation time in a state in which the temperature is not measured by the temperature measuring means. Thus, when compensation is made for the measured flow rate to derive a flow rate at a desired temperature, flow rate compensation can be implemented with high accuracy, versatility of a target fluid can be improved, and low electric power consumption can be achieved.

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.
