摘要： An ultrasonic flow rate measurement device capable of sensing and correcting a temperature without use of a sensor specifically designed for measuring a temperature is provided. The ultrasonic flow rate measurement device includes a first ultrasonic transducer and a second ultrasonic transducer that re disposed in a flow volume measurement block and arranged in such a way that ultrasonic waves are transmitted from one transducer and received by the other transducer; a counter for measuring a propagation time consumed for exchanging the ultrasonic waves between the first ultrasonic transducer and the second ultrasonic transducers; a flow volume computing block that calculates a flow volume from a measurement value of the counter; an oscillation circuit used as a time counter when the counter calculates the propagation time; and a temperature sensing block for sensing a temperature by utilization of a frequency change attributable to a temperature of the oscillation circuit.
