摘要：

This paper continues the research presented at the IMEKO XV World Congress in Osaka/JP. It gives deeper insights into the topic of measuring the average volume flow with ultrasound based flow meters in a pulsating fluid. Pulsations are very common in industrial applications so that flow meters have to cope with this kind of disturbances. Especially ultrasonic flow meters are expected to react very sensitively to this effect because they measure any kind of pressure changes. By generating pulsations with a rotating paddle the following article will give impressions about possible influences and the maximum operating range of a cross-correlation and a vortex frequency meter. In addition to the IMEKO basic interpretations are proved by new theoretical considerations. (C) 2001 Elsevier Science Ltd. All rights reserved.
