DEVICE FOR DETERMINATION AND/OR MONITORING OF THE VOLUMETRIC AND/OR MASS FLOW OF A MEDIUM

摘要

The invention relates to a clamp-on ultrasound throughflow measuring device (1), for determining the volumetric and/or mass flow of a medium (2) in a container (7). The aim of the invention is the production of a clamp-on ultrasound measuring device (1) with low temperature dependence. Said aim is achieved, whereby the coupling element (11, 12), by means of which the ultrasound measuring signal is injected into the container (7), or extracted from the container (7), comprises at least two partial elements (13, 14) which are embodied and/or arranged such that the given injection angle into the container (7) and the given extraction angle from the container (7) are approximately constant over an extended temperature range.
