Sampling Systems

DPM Back Purge Configuration (A4)

The ability to back purge the sample point ensures optimal retrieval of a representative liquid sample. The DPM type sampler in back purge configuration allows a gas to purge the sampler prior to sampling ensuring a fresh sample at a recommended maximum operating pressure of 8 bar. This liquid sampler offers one-handle operation, providing safety for the operator and zero emission.

Provide a new septum on your sample bottle. Insert the bottle, with cap and septum into the sleeve until the septum is pierced by the needles. Put the bottle retaining clip in place.

Turn the handle to “back purge” position, allowing a flow of purge gas through the sampler to the process to ensure representative sampling. This position can be held for any required time.

Turn the handle to the “sample” position, allowing the product to flow into the sample bottle. When the required amount has been taken, turn the handle to the “off” position.

Remove the bottle retaining clip and pull the bottle out from the sleeve. The septum reseals automatically.
