    • A portable delivery system for delivering a multiple part coating composition for in situ coating an internal pipeline surface comprises a housing including a controller, at least two composition containers, a first hose, a hose delivery system, a pump, and at least two mass flow meters. The composition containers contain differing compositions, and each container includes a composition depth monitoring apparatus. The first hose comprises at least two additional hoses, where two of the additional hoses each deliver one of the compositions to a composition applicator. The hose delivery system stores and delivers the first hose to the pipeline, and the pump is coupled to the composition containers and the first hose. The mass flow meters are each coupled to a pump outlet corresponding to an outlet of the respective first or second composition container.
