Welker - Model SSM-1 -Spot Sampling Manifold

Two styles of SSM-1 offer different levels of liquid separation upstream of the sample cylinder for a more representative spot sample. For free liquid removal, the standard SSM-1 with a Welker DP-15 Drip Pot is the answer. Acting as a sample line separator, the DP-15 collects free liquids from gaseous flow. Where created liquids are a primary concern, swap the DP-15 for a Welker Fluid Sentinel. The Fluid Sentinel combines a liquid separator and a sight glass to prevent free liquids from reaching the sample cylinder while allowing technicians to monitor the sample stream for present or created liquids.

Far and Away
Offset the Joule-Thomson Effect

Pressure and temperature changes that occur during repeated fill and empty cycles have the potential to distort your sample. The SSM-1’s pigtail keeps your sample representative by distancing the flow restriction from the sample cylinder. Pressure reduction during an empty cycle occurs at the pigtail’s valve, preventing the Joule-Thomson effect from cooling the cylinder and potentially condensing the sampled gas. When using an SSM-1 with Welker Fluid Sentinel, the technician can visually monitor the sample stream for created liquids and modify the spot sampling technique as necessary.
