A densitometer suitable for fluid measurements in remote, hostile environments comprises one or more pairs of matched weight masses housed within a tube and having respectively different densities. When immersed in the subject fluid, the buoyancy differential between the masses is converted to a proportional torque oriented about an axis aligned substantially parallel with a pipe bore. The torque is transferred through a calibrated environmental isolation cylinder to an electric property sensor positioned in a protected environment. A proportionalized electric property signal is transmitted to a value reading station.
