A float for use in a fluid measurement device, symmetric about a central axis and containing an aperture along the axis which may be sized differently according to each float. When used in a rotameter type flowmeter, greater range and sensitivity in readings is permitted as compared to standard floats, by allowing fluid an additional orifice through which to pass. The improved float also allows multiple ranges of viscosity to be measured when used within a falling float type viscosimeter by selection of different size float apertures.
