It is an object to provide an ultrasonic flow measuring device which can accurately determine the orientation and position of a ultrasonic transducer to be secured and enhance workability such as reduction in working time. In order to attain the object, ultrasonic transducers (20) are fixed so as to be spaced from each other at a regular interval by using a positioning portion (41) of a positioning frame (40). The position adjustment of the ultrasonic transducers (20) is automatically carried out by a positioning spring (25b) and the positioning portion (41). On the other hand, a guide frame (30) can be mounted at a proper place of a conduit pipe (10) irrespective of the installation of the ultrasonic transducers. For the mounting of the guide frame (30), it is unnecessary to pay attention to an interval adjustment between the ultrasonic transducers and also it is unnecessary to coat acoustic coupling medium on the conduit pipe, so that the selection of a setup place, etc. can be freely performed. After rough assembly, required acoustic coupling medium is coated on the ultrasonic transducers, and the positioning frame (40) is fixed to the guide frame (30), whereby the regular orientation and position can be applied to the ultrasonic transducers. <IMAGE> |
