rotameter

Also found in: Dictionary, Encyclopedia, Wikipedia.

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]
