ro·tam·e·ter

(rō-tam'ĕ-tĕr),
A device for measuring the flow of gas or liquid; the fluid flowing up through a slightly tapered tube elevates a ball or other weight that partially obstructs the flow, until the wider cross-section allows that flow to pass around the floating obstruction.
[L. rota, wheel, + G. metron, measure]

rotameter

(rōt′ă-mēt″ĕr, rō-tam′ĕt-)

The flow rate was adjusted by changing the valve opening in supply pipe direction and reading the rotameter device.
986 was used, and the actual flow rate was measured with a Yokogawa rotameter.
Overland flow was supplied by a constant flow regulated with a rotameter and applied via a reservoir attached to the upper end of each soil plot to maintain a uniform flow depth over the entire soil surface.
