Sentry MLG Manual Sampler for Liquefied Gases

Part #
Sentry MLG Sampler

The Sentry MLG manual low emission sampler is ideal for sampling liquified petroleum gas (LPG) and other two-phase liquids—gases that are pressurized, stored and transported in their liquid phase—with high vapor pressures.

The Sentry MLG sampler incorporates a number of features to provide for safe, simple and representative sampling. The six-port tandem valve simplifies sampling by replacing multiple valve operations with just one ergonomically-designed valve. The sampler action is repeatable, so the sample is always as representative as possible.

By using an expansion vessel to reduce sample cylinder volume after the sample is captured, both safety (outage space for transport of the cylinder assembly) and representative sampling are assured for the most accurate data analysis results.


  • Flow-through design assures representative sample
  • Tandem switching valve integrates multiple functions into one device
  • Self-sealing quick disconnects for easy removal and transport of sample cylinder
  • Various volume-reduction methods to meet regulatory "maximum fill density" requirements
  • Ergonomic design reduces turning torque and eliminates repetitive wrist action
  • Variety of configurations to meet any gas sampling need
  • Options include sample cooler, in-line filter, cooling water valves, check valves, carbon canister, nitrogen purge, flow indicator, cylinder relief valve, rupture disc, pipe stand, heater and enclosures; valve package for applications without process return
