selection of sensitivity range
The water sample taken from the cooling water cycle must flow continuously
through the oil detector & alarm ORGS 11-2. We recommend a flowrate of 200 l/h.
The sampling of the cooling water should take place downstream of the location of
a potential oil leakage at the highest point and, if possible, in a horizontal line.
Since the oil flows in the upper part of the pipe we recommend the installation of a
welding pocket according to DIN 2618 for collecting the oil droplets. The line
leading to the measuring pot of the ORGS 11-2 should be vertically ascending,
running directly into the bottom part of the measuring pot. Avoid any narrow parts
in the supply line since they could give rise to undesired emulsification of the oil.
If space is a consideration and the measuring pot has to be installed at a lower
point make sure that the line leading to the measuring pot features sufficiently
sized bends in order to prevent emulsification.
