Smart entertainment atomisation mixing system

A nozzle 100 for injecting a first liquid mass into a stream of second liquid mass flowing within a pipe, the nozzle comprising a first outer cylinder 103 and second inner cylinder 104 which are concentrically arranged about a nozzle axis, securing means 105 for securing the nozzle to a wall of the pipe with the nozzle axis orthogonal to the pipe wall such that the nozzle projects into an interior of the pipe in use, and duct means 101, 102 for receiving the first liquid and transporting it to the interior of the inner and outer cylinders wherein the inner cylinder comprises at least one hole 107 arranged to expel liquid and the outer cylinder comprising at least one hole 106 arranged to expel liquid. The nozzle forms part of a mixing system wherein the first liquid is withdrawn from the second liquid flowing within the pipe at a position downstream of the nozzle. A portion of the first liquid is analysed, the first liquid is recirculated back into the flowing second liquid via the nozzle with the outer cylinder receiving the bulk of the first liquid and the inner cylinder receiving the portion of the first liquid that has been analysed.
