Fixed Volume Liquid Sampler

The Fixed Volume Closed Loop Liquid Sampler is designed to provide a fixed volume sample independent of process pressure or flow rates, while keeping the operator isolated from the process stream and line pressure.

This simplified, one-valve design allows for volume accuracy while obtaining a representative, emission-free sample safely. A pre-measured volume of sample is isolated and moved to a sample vial with a carrier gas. This system is a true dead volume sampler, as it and the sample vial are fully purged during the sample cycle, providing an inert atmosphere prior to each sample. The panel mounting allows for easy pipe, wall, or flange mounting.

The Fixed Volume Closed Loop Liquid Sampler can be designed to work automatically as a multi-vial sampler or as a composite sampler.
