Measuring arrangement for contactless determination of location-related physical characteristics within flow volume of e.g. air in medical field, has measuring devices measuring differently oriented measuring section within flow volume

摘要

The arrangement (1) has four measuring devices (20, 30, 40, 50) measuring a measuring section within flow volumes of a medium e.g. air. The measuring devices are arranged outside of the flow volumes at four measuring positions. The measuring devices detect the running time and/or the amplitude of a measuring signal. The measuring devices are movably arranged between two measuring positions for measuring differently oriented measuring section within the volume in a translatory and/or rotational manner. An independent claim is also included for a method for contactless determination of location-related physical characteristics within flow volume of a medium.
