Rotameter
Rotameter (ˈrəʊtəˌmiːtə) n (General Physics) trademark a device used for measuring the flow of a fluid. It consists of a small float supported in a tapering glass by the flow of the fluid, the height of the float indicating the rate of flow
rotameter
rotameter[rō′tam·əd·ər] (engineering) A variable-area, constant-head, rate-of-flow volume meter in which the fluid flows upward through a tapered tube, lifting a shaped weight to a position where upward fluid force just balances its weight. rotameter
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-) A device that measures the flow of a gas or liquid by rotating as the fluid passes the fins or blades of the device. |
