Installation requirements
– continued –
1. Use supporting flanges to install the oil detector ORGS 11-2 in a suitable place.
2. Connect the supply line, the return line and the drain line with the cutting ring
screwed unions of the ball valves in a pressure-tight manner.
3. Close ball valve and open ball valves and . If the cooling water line is under
pressure the rapid-action deaerator will vent the ORGS 11-2.
Note
■ Please pay attention to the examples of installation on page 17
(figs. 13 and 14).

ORGS 11-2
To achieve the recommended flowrate of approx. 200 l/h provide the main cooling
water line with a standard orifice plate in order to throttle the flow velocity between
the water sampling location and its re-entry point.
The pressure drop
∆∆∆∆∆
p
v
across the measuring pot is 0.06 bar.
The pressure drops of the connecting lines depend on the design and layout of the
installation and must be ascertained individually. The calculated resistance
coefficient
ζ
can be used to determine the opening ratio and, consequently, the
required diameter d for the opening of the standard orifice plate.
For more information on the sizing and layout of fluid dynamic systems please refer
to the corresponding technical literature and relevant standards.
