✦ Synopsis

An equation of motion is derived for the float in a rotameter. An approximate solution for sinusoidal pulsations is given. The transfer function resulting from this solution and the error in the indicated mean flow are compared with measurements and show good agreement. In particular it is shown that the error in the indicated mean value can sometimes be reduced by choosing suitable dimensions for the float. For gases, the occurrence of float instability (bouncing) is investigated. Measurements of this phenomenon are compared with theory and show good agreement.
