Venturi tube

(vɛnˈtʃuːrɪ)
n
1. (General Physics) physics a device for measuring fluid flow, consisting of a tube so constricted that the pressure differential produced by fluid flowing through the constriction gives a measure of the rate of flow
2. (General Physics) Also called: venturi a tube with a constriction used to reduce or control fluid flow, as one in the air inlet of a carburettor
[C19: named after G. B. Venturi (1746–1822), Italian physicist]

ven•tu′ri tube`

(vɛnˈtʊər i)
n.
1. a device for measuring fluid flow, consisting of a tube constricted in such a way that a pressure differential is created between the center and the ends.
2. an alteration in the shape of the throat of a carburetor for controlling the flow of fuel.
[after German. B. Venturi (1746–1822), Italian physicist]
