Abstract

An ultrasonic wave passes different fuels of different concentrations with different velocities. The present invention provides a detecting and controlling device where, by a non-touching method, a velocity for an ultrasonic wave in a first fuel with a first fuel concentration is measured. The velocity obtained is taken for a comparison with another velocity for the same ultrasonic wave in a fuel with a default fuel concentration so that the first fuel concentration of the fuel can be under controlled.
