Abstract

Provided is a flow rate adjusting device including: an ultrasonic flow metering portion; a flow rate adjusting portion; a flow rate setting unit; a flow rate fluctuation state detecting unit configured to detect a flow rate fluctuation state where a first flow rate state where a measured flow rate value is higher by at least a first threshold than the set flow rate value and a second flow rate state where the measured flow rate value is lower by at least a second threshold than the set flow rate value occur; and a control device. The control device controls the flow rate adjusting portion to move the valve body by a first motion amount when no flow rate fluctuation state is detected and controls flow rate adjusting portion to move the valve body by a second motion amount less than first motion amount when flow rate fluctuation state is detected.
