Installation
OR 52-7
Use the support and install the measuring sensor ORG 2 as close as possible to the separator in
order to keep the supply delay to a minimum. According to MEPC. 07 (49) in the event of an alarm
(oil content =/> 5 ppm) the contaminated water must be diverted from the separator to the bilge as
quickly as possible, i. e. within no more than 20 seconds.
Use a 0x mm copper or stainless steel pipe to connect the measuring sensor ORG 2/22 with the
sampling point of the separator and the clear water supply. The sampling point should be provided in a
vertical section of the separator outlet pipe so as to avoid any impairment caused by air bubbles.
In order to ensure that the arrangement for the extraction of samples gives a truly representative
sample make sure that the fluid flow always passes through the sensor under all operating conditions
and that any by-passing of the oil separator is prevented.
If it is not possible to provide the sampling point in a vertical pipe, a lateral arrangement in a horizontal
pipe is also possible.
For overboard pipes having an outside diameter of up to 75 mm a tee piece for the extraction of
samples can be used. If the size of the pipe exceeds 80 mm, make sure that the sampling arrange-
ment extends approx. 25 % into the overboard line.
Install the vacuum breaker above the highest point of the oil separator.
Attach the measuring transducer ORT 7 to a stable vertical surface. If possible mount the indicator at
eye level for easy viewing and provide sufficient space for service and maintenance work.
The measuring transducer is designed for wall mounting. The distances between the fixing holes are
indicated on the back of the equipment.
To access the fixing holes undo the cover screws and open the cover.
