Online density measurement using a non-nucleonic technology utilises real-time, inline measurement of a ultrasonic wave through a material such as a slurry. By measuring the speed of the wave through the slurry, the attenuation of the signal and the response at the slurry interface, accurate density measurement can be achieved without the use of a nuclear device.

Density Measurement in Power Plants

Traditionally, density measurement in both processes has been carried out using nucleonic devices. But with a strong desire by power plants to move away from online density monitors using gamma radiation sources for both safety and cost reasons, ultrasonic density measurement systems are replacing them all over the globe.
