Abstract
An improved electronic monitoring arrangement for a rotameter utilizes a single point source of radiation at one side of the rotameter and a vertical array of detectors diametrically opposite to it. The elevation of the radiation source is identical to the uppermost elevation of the radiation detectors. Radiation from the source will thereby intersect a common remote edge of the top surface of the float within the rotameter throughout its intended range of movement along the elevation covered by the array.
