Fluid Density Tools - Radioactive (FDR)

The radioactive fluid density tool provides a reliable and comparatively safe means to measure wellbore fluid density, regardless of the well deviation and flow rate. A low-energy Americium-241 gamma ray source is used, which generates radiation rays to a distance of one meter from the tool. The radiational section is shielded so that the measuring is minimally negatively affected by radioactive scale. The very high count rate provides excellent data. A radiation shield is provided which can be locked on the tool so that the source can stay in the tool between jobs.
