Abstract: The present invention provides an anaerobic digestion reaction system. This system includes a continuously stirred reaction tank having an agitator contained therein and one or more outlet pipes. A blend tank for receiving organic waste feedstock is in communication with the continuously stirred reaction tank. Organic waste feedstock is transferred from the blend tank into the continuously stirred reaction tank. A plug flow reactor is in communication with the continuously stirred reaction tank. The organic waste feedstock is transferred from the continuously stirred reaction tank into the plug flow reactor to conduct stages of biomass reaction of the organic waste feedstock into biogas and creating organic waste material. The organic waste material and biogas is discharged from an outlet pipe and into an outlet gas separation vessel tank. In this tank, the biogas is separated from liquids and solid slurried waste.

Abstract: Particle and multi-phase system monitoring methods, systems and apparatus are disclosed. Preferred embodiments comprise one or more mechanical resonator sensing elements. In preferred embodiments a sensor or a sensor subassembly is ported to a fluidized bed vessel such as a fluidized bed polymerization reactor.
