Temperatures near or below the hydrocarbon dew point can cause sample distortion. Where phase change is a concern, the Welker HGS Heated Gas Sampler can help. Contained within an insulated enclosure, the HGS mounts directly to the pipeline. The heater maintains a temperature above the hydrocarbon dew point for representative composite samples. Connect your sample probe to the sampler subassembly to collect fresh samples proportional to flow or time.
The HGS is ideal for natural gas at or near the hydrocarbon dew point.
Key Features
- Welker Fresh Sample System™
- Positive displacement piston sample pump
- Inline relief at sample outlet
- Purge manifold with pressure gauge
- Heater with thermostat
- Insulated corrosion-resistant enclosure with external temperature gauge
- Optional onboard Welker 6Tc Timer/Controller
Key Benefits
- Self-purging design ensures a fresh sample every cycle
- Collect repeatable fixed volume samples at line pressure
- Inline relief prevents collected samples from flowing back to the pipeline if pipeline pressure drops
- Maintain an internal temperature above the hydrocarbon dew point to prevent condensation
- Confidently sample in harsh environments and remote locations
- Sample proportional to flow or time without an external power supply (optional)
