摘要： PROBLEM TO BE SOLVED: To eliminate the effect of fluctuation of sensor output signal arose from measuring in high flow-rate domain. SOLUTION: Both the display resolution when displaying flow-rate on an indicator 193 and the resolution when performing flow-rate setting of fluid to be measured passing through a channel 12 are made to be altered depending on flow-rate. Namely, by reducing the display resolution when displaying flow-rate on an indicating section in low flow-rate domain with small fluctuation of displayed value, whereas by enhancing the display resolution in flow-rate domain with large fluctuation, flow-rate measurement can be possible without fluctuation of displayed value. By establishing the resolution in the similar fashion when performing flow-rate setting, flow-rate control can be possible without effect of fluctuation of displayed value.
