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 transducersare fixed with a proper interval therebetween using a positioning portionattached to a positioning frame. The position adjustment of the wave transduceris automatically carried out through a positioning springand the positioning portion. A guide framecan be mounted at a proper position on a conduit pipeirrespective of the installation of the wave transducer. The guide frameis 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 frameis attached to the guide frame, so that the right directions and positions can be applied to the wave ultrasonic transducers.
