Abstract
Disclosed is an ultrasonic Doppler flow measurment system that achieves flow measurement regardless of the temperature of a fluid. A temperature sensoris combined with a pipeto measure the temperature of a fluidA controllercalculates a frequency that will cause cavitation when an ultrasonic transducerexerts an ultrasonic vibration on the fluidon the basis of a temperature measured by the temperature sensorand controls a sinusoidal oscillator
