Welker Probe Regulators provide single-step
product pressure reduction from the pipeline, giving a regulated
sample supply for chromatographs, H2S
analyzers, gravitometers, calorimeters, moisture analyzers or
other on-line analysis equipment. Two different models are available
for either permanent installation (inserted directly into the
line) or removable installation (inserted through a valve without
interrupting product flow with the use of Welker's patented
Automatic Insertion Device). Thermal fins on the probe offset
temperature changes at the point of regulation. In addition,
the diaphragm design of the probe regulators gives increased
low pressure sensitivity.
