Abstract

An apparatus may include a mud pot and a reflectometer to monitor a level of an interface between liquid diluent and catalyst slurry in the mud pot using reflectometry. The apparatus may include a mixing tank and a conduit to transfer catalyst slurry from the mud pot to the mixing tank. The apparatus may include a polymerization reactor and a conduit to provide catalyst slurry from the mixing tank to the polymerization reactor.
