Abstract
The ultrasonic flow meter of the present invention comprising a measuring pipe through which liquid flows, and two measuring units provided at an interval in the lengthwise direction on measuring pipe. A tightly adhered tube having elasticity is attached to an attaching indentation formed in the measuring pipe over the peripheral direction, and its inner peripheral surface is tightly adhered to the outer peripheral surface of measuring pipe. A transducer is arranged on the outer peripheral surface of tightly adhered tube in the state in which it is pressed against the outer peripheral surface of the tightly adhered tube. In this ultrasonic flow meter, the transmission of vibrations between the transducer and fluid inside the measuring pipe can be carried out uniformly.
