Welker - Model HGS -Heated Gas Sample
The Welker HGS Heated Gas Sampler is a composite sampling solution for natural gas at or near the hydrocarbon dew point The HGS maintains the sampling equipment above the hydrocarbon dew point to ensure composite samples are representative and not distorted by phase change. Connect the HGS to a sample probe to collect fresh samples proportional to flow or time.
