WELKER PROBE REGULATORS

WELKER PROBE REGULATORS

Welker Probe Regulators provide a regulated sample supply of liquid or gas product from a pipeline to chromatography H₂S analyzers, gravitometers, calorimeters and other on-line analyzing equipment.
Two models are available-a Standard Probe Regulator that is designed to be installed in the pipeline,and an Automatic Insertion Probe Regulator that is designed to be inserted into (and withdrawn from) a pressurized pipeline (maximum operating pressure 1800psig) without pipeline shutdown.
On both models, the inlet is positioned on the end of the probe to enable it to collect product from the central portion of the pipeline-giving you a more representative sample. Both probe regulators inhibit carry-over of free liquids into the instrument supply system.
The diaphragm design of the Probe Regulator allows it to respond quickly to sensitive changes in outlet pressure, making it well suited for applications requiring an accurately regulated source (down to 0 psig).
The Automatic Insertion Probe Regulator allows the operator to control the movement of the regulator in and out of the pipeline safely-through the use of three control valves on the oil reservior. This is especially advantageous in applications where it is inconvenient to interrupt the flow in the pipeline.
