LSSM-1PM

LSSM-1PM

Compact Composite Sampler

The Welker LSSM-1PM is a self-purging positive displacement pump designed to take quality samples proportional to flow or time. Connect a controller signal, pneumatic supply, and sample container to this probe-mounted sample pump and you’ve got a complete liquid sampling system.

Probe Mounted
In the Short Run

Eliminate Lag Time

Mounted on a Welker Pitot Probe, the LSSM-1PM can be installed directly to the pipeline without long tubing runs to impact the timeliness and representativeness of samples. The close proximity to the process and product circulation loop created by the Pitot Probe ensure fresh product is continually presented to the sample pump.

Vanishing Act

Unique Collection Head

Capture set volumes of sample in real-time with the Vanishing Chamber™ collection cup. Each actuation of the sample pump voids the collection cup, fully displacing the sample into the connected sample container.

Without Interruption

Easy Maintenance

There’s no need to depressurize your pipeline and remove the LSSM-1PM for standard maintenance. Simply closing the valves on the Pitot Probe isolates the sample pump from process pressure, enabling you to safely remove the sample pump.
