Abstract
A fluid meter (10) has a casing (11) providing a measuring chamber (27) and an inlet (18) and outlet (19) communicating with the measuring chamber (27). A partition (20) in the chamber (27) separating said inlet (18) from said outlet (19). A disc (28, 48) is positioned in the chamber (27) and includes projections (36) or niches (57) which are disposed in an arc relative to a center of the disc (28, 48) and the casing is provided with integrally formed depressions (37) or with projections (56) disposed opposite the projections (36) or niches (57) on the disc (28) to be engaged the disc (28) as the disc (28, 48) is nutated with the result of counteracting forces imposed on said disc (28, 48) by fluid flow.
