Request Information
  • The ability to purge the sample point ensures optimal retrieval of a representative liquefied gas sample.
  • The S32-LG type samplers in vent to flare configuration provides a system purge in addition to sampling in a sample cylinder with a predefined filling rate.
  • The predefined filling rate is achieved by using an expansion chamber.
  • This liquefied gas sampler is equipped with an additional valve on the process outlet.
  • Ensuring filling of the cylinder with liquid when difference between inlet and outlet pressure is significant.
  • The unique design offers one-handle operation by multiple valves.
  • These features provide sample accuracy, safety for the operator and the possibility of zero emission.
  • This sampler type is suitable for liquefied gas and liquid with high vapor phase.
