Abstract: An ultrasonic flow rate measuring device, especially a clamp-on type, is mounted on a line through which medium flows with at least one ultrasonic transducer and a guide frame for guiding and holding the ultrasonic transducer. A fixing mechanism allows the ultrasonic transducer to be moved onto the line or away from the line and also allows it to be axially moved and fixed on the guide frame or unclamped from it. The ultrasonic flow rate measuring device is able to be easily unclamped for maintenance and repair purposes and then re-attachable to the line in the original configuration.

Abstract: An ultrasonic flow rate measuring device for measuring the flow rate of a medium flowing through a line (1), with at least one ultrasonic transducer (2) and a guide frame (3) for guiding and holding the ultrasonic transducer (2). An electrical connecting box (12) which has a connection (13) for a cable (14) to the ultrasonic transducer (2) and a connection (15) for a cable (16) to the measuring device electronics is provided. Thus, in a clamp-on ultrasonic flow rate measuring device, simple cabling is achieved.

Abstract: A process and device for mounting a clamp-on flow rate measurement device on a measurement pipe using a mounting device having a holding strap with catches. The holding strap can be fastened on the measurement pipe by the holding strap being guided into and through the catch and tightened. A holder is attached to the holding strap to which the clamp-on flow rate measurement device can be fastened. First the mounting device is mounted on the measurement pipe, afterwards the clamp-on flow rate measurement device is attached to the holder without the holding strap being completely tensioned, so that the clamp-on flow rate measurement device is loosely held on the measurement pipe. Then, after aligning the clamp-on flow rate measurement device is, the clamp-on flow rate measurement device is completely attached to the holding means by further tensioning of the holding strap by lifting the catch off the measurement pipe.

Abstract: A clamp-on measurement device, for attachment to a support, with at least one instrument transformer, a retaining device for holding the instrument transformer and a fastening device (4) for attachment of the retaining means to the support. The retaining device can be attached to the fastening device (4) such that the retaining device can be moved in at least one predetermined direction away from or toward the support and can be pivoted along a pivot axis which runs preferably perpendicular to the predetermined direction. This results in the clamp-on measurement device, after attachment to a support, being easily disengaged from the support for maintenance and repair purposes and then can be reengaged with the support without losing its original alignment.
