Vibration tests in accordance with DIN EN 60068-2-6 and IEC 68-2-6 were performed on two flowmeters of type D4_F. The flowmeters were manufactured by ABB Automation GmbH Göttingen and are of design status C. They have a nominal diameter DN20 and the labelling VT-1-20 and VT-3-20. The flowmeters were mounted on a uni-axial electrodynamic shaker. For each longitudinal axis of the flowmeters 100 cycles of sine sweep runs from 10 to 150 Hz upwards and from 150 Hz to 10 Hz downwards with a sweep velocity of 1 oct/min and a level from 2 g were performed. In each axis the flowmeters were exposed 13 h to the vibrations. The visual inspection of the flowmeters after each test run showed no visible damage. After termination of the test programme, the flowmeters were transported to ABB and inspected in detail. Also, the calibration was checked by ABB.
