Accurate and cost effective interface/level measurements are available with Neutron Backscatter. This technology is based on detecting relative differences in hydrogen concentration. High energy neutrons are emitted from the Am-241 source and are scattered back as low energy thermal neutrons. The low energy neutrons are then counted with a neutron detector. Plotting the resulting counts yields subtle differences that represent different types or phases of the material inside the vessel or pipe.

NEUTRON BACKSCATTER TANK APPLICATION
Neutron Backscatter is utilized for numerous types of measurements. One common application is storage tanks (both circular and spherical). Storage tanks are scanned at several points round the circumference in order to develop a profile of the product inside the tank (hydrocarbon, water, sludge, etc.).
