A flow density tool having a flow housing with an inflow orifice and outflow window and a sensor tube inserted from an end opposite inflow orifice. Two symmetrically placed nuclear sources are covered with a lead blanket from the outside so that the sensors are exposed only to the given source and covered by the same blanket from outside or external radiation to allow the flow density of a continuous flow of discreet media to be measured.
