Constant pressure sample containment from collection to laboratory analysis
The Welker CP-2 Constant Pressure Cylinder is designed for safe collection, transport, and containment of accurate natural gas and light liquid hydrocarbon samples for laboratory analysis. Built to maintain sample integrity at full line pressure from collection through analysis, the CP-2 uses a floating piston, product and pre-charge sides, and an Internal Gravity Mixer™ to help protect against phase change and ensure a properly mixed sample. Suitable for spot or composite sampling, high-BTU natural gas, calibration standards, and lab containment, the CP-2 helps reduce excessive purging and venting while supporting repeatable, reliable analytical results.
Natural Gas and Light Liquid Sample Collection
Spot or composite sampling for the safe collection and transport of natural gas, high-BTU natural gas, and light liquid hydrocarbon samples
Calibration Standard Containment
Containment and maintenance of calibration standards for field calibration of online analyzers or laboratory use
Complies With:
Proven Safety in Cylinder Design
Allows operators to control and monitor pressure throughout sample collection, transport, and analysis.
Maintains Sample Integrity at Full Line Pressure
Helps preserve accurate sample conditions from collection to laboratory analysis.
Product and Pre-Charge Sides With Floating Piston
Pre-charging the back side of the piston helps protect the sample against phase change.
Internal Gravity Mixer™
Provides a proper sample mix to support accurate and repeatable lab analysis.
DOT and Transport Canada Approval for Transportation
Supports safe and compliant sample transport for approved cylinder configurations.
Precision Engineered
Delivers a field-proven constant pressure cylinder design built for reliable, repeatable sampling results.
