Abstract
To suppress the generation of bubbles of gas dissolved in a fluid, a flow evaluating portion compares a measured flow rate value with a preset reference flow rate value and determines whether a fluid is flowing through a measurement tube. When the flow evaluating portion determines that the fluid is not flowing through the measurement tube, a magnetic excitation controlling portion imposes a limitation so that a magnetic excitation current reduces to an electric current value less than a magnetic excitation current obtained in normal measurement. When the flow evaluating portion determines that the fluid is flowing through the measurement tube, the magnetic excitation controlling portion releases the limitation on the magnetic excitation current.
