The Mustang® Composite Sampling System (MCSS) is a continuous waterless type sampling system that provides a representative gas composition sample by taking small bite size samples over a period of time. The MCSS consists of the HMI/SCADA control software and the composite sampling system. Sample pumps, the grab sample cylinders, and the composite sample system are housed within the system. The control station houses the PLC which controls all solenoid valves and indicator lights.

The MCSS grabs a fresh, 0.5 cc, sample every second, storing it in the accumulator for future analysis. Once sampling is complete, the composite sample can be transferred to the portable sample cylinders for lab analysis. The MCSS has three purging options which include an accumulator with an internal bladder, vacuum pump, or venturi vacuum generation. The accumulator is then emptied and the system reset for the next ship.
