The Mustang® Pressure Regulating Vaporizer Sampling System Jr. is a technology designed to vaporize liquid providing a fresh sample to a continuous online analyzer where economy is of priority.  The MPRVSS Jr. (or the NGL Jr.) has the controller located within the cabinet and no liquid block.  For external controller features and added liquid block, see MPRVSS.

This system is designed with enhanced sample quality, through controlled vaporization and remixing, and gas sample pressure reduction.

In order for the analyzer to meet it’s stated accuracy, the Mustang® Pressure Regulating Vaporizer Sampling System ensures the sample to the analyzer is in a stable composition. The single-path design is suitable for sample conditioning where redundancy is not a concern.
