Abstract
A metering device for multiphase fluid, for example, crude oil, comprises a .gamma. or X-ray densitometer incorporating windows for the metering radiation of boron carbide. The boron carbide windows can be provided by a sleeve guiding the fluid flow, the sleeve (51) being reinforced by a thin external layer (52) of carbon fiber embedded in epoxy resin. Alternatively, a steel tube (26) receiving the fluid flow has aligned transverse apertures (47) containing plugs (49) of boron carbide.
