Vibration Tests on Two Flowmeters of Type VT-150-1 and VT-150-2

Kurzfassung

Vibration tests in accordance with DIN EN 60068-2-6 and IEC 68-2-6 were performed on two flowmeters of type VT-150-1 and VT-150-2. The flowmeters were manufactured by ABB Automation GmbH Göttingen and have both a nominal diameter of 150 mm. The design of the flowmeter measurement mechanisms are slightly different. The flowmeters were mounted on a multi-axial test facility and sine sweep runs into the direction of the three translational axes were performed. The frequency range of the sine sweep runs was 10 to 100 Hz with a maximum acceleration level of 3 g. In each axis the flowmeters were exposed 66 min 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.
