It is an object to provide an ultrasonic flow amount measuring device in which a direction and position of a transducer can be accurately fixed, thereby improving workability such as a reduction in working time. In order to attain the object, ultrasonic transducers 20 are fixed with a proper interval therebetween using a positioning portion 41 attached to a positioning frame 40 . The position adjustment of the wave transducer 20 is automatically carried out through a positioning spring 25 b and the positioning portion 41 . A guide frame 30 can be mounted at a proper position on a conduit pipe 10 irrespective of the installation of the wave transducer. The guide frame 30 is mounted without paying attention to an interval between the ultrasonic transducers and coating an acoustic coupling medium on the conduit pipe, so that selection of a setup place, etc. can be freely performed. After pre-assembly, the required acoustic coupling medium is coated on the wave ultrasonic transducers, and the positioning frame 40 is attached to the guide frame 30 , so that the right directions and positions can be applied to the wave ultrasonic transducers.
