A dynamic viscosity  factor nu depending on a temperature is calculated through temperature measurement and the flowing velocity of a fluid is calculated based on the applied magnetic field density and detected electromotive force. After these steps, these factors are combinated to obtain Reynolds number  and a flow distribution is computed based on the separately established relationship between the  Reynolds number and the flow distribution. The above-mentioned factors are applied to a flow  formula to obtain a flow velocity. This process is sequentially calculated with the assistance of the  arithmetic operators 5, 6 to finally calculate a flow. Thus a flow Q can be obtained over an extensive range of Reynolds numbers with high precision.
