7 Piping

The instrument has to be supplied with a representative sample of the separator
effluent water stream. The sample stream through the instrument is
recommended to be approx. 2 Liters per Minute.
Connect the OMD-2008 EV-FC Monitor to the sample point of the oily-water
separator outlet and to a source of oil free water. Fittings on the Instrument are
for 6 mm OD copper or stainless steel pipe. Adapter fittings for other pipe
diameters are available upon request.
The sample point should be located on a vertical section of the separator outflow
piping to minimize the effects of any entrained air. The tapping point should be at
a level above the outlet of the monitor to ensure the sample cell is flooded at all
times.
If connection to a vertical section of the separator outlet piping is impractical, the
tapping may be made into the side of the horizontal pipe. Avoid top or bottom
entry.
For separator discharge pipes up to 75 mm OD a standard "T"-type junction of
the welded or screwed type is satisfactory for the tapping point. For the separator
discharge pipes of 80 mm OD and above a sample probe should be employed
which protrudes into the discharge piping by approx. 25 % of the ID of the pipe.
