PROBLEM TO BE SOLVED: To measure the viscosity of a mixed liquid and the mixing ratio with water accurately by making constant the flow rate of an emulsified mixed liquid of water and oil and operating the viscosity from the pressure difference of a thin tube passing the mixed liquid whereas operating the ratio of water from the heating temperature difference of the mixed liquid. SOLUTION: A fixed volume pump 1, a thin tube 2 and a heater 3 are arranged in series and pressure gauges 5, 6 are provided at the inlet and outlet of the thin tube 2 while thermometers 8, 9 are provided at the inlet and outlet of the heater 3. A first operating unit 7 is previously inputted with the radius R and the length L of the thin tube 2 and the flow rate Q of an emulsified mixed liquid of water and oil is predetermined by the fixed volume pump 1. Consequently, the absolute viscosityηof an emulsion fuel can be operated according to formula I when the inlet and outlet pressures P1, P2 of the thin tube 2 are introduced. A second operating unit 10 is previously inputted with the specific heatλw of water, the specific heatλo of fuel, the flow rate Q and the heat quantity H. Consequently, the ratio of waterαcan be operated according to formula II when the inlet and outlet temperatures T1, T2 of the heater 3 are introduced.
