This manual provides user information for the basic routine operation of the Advanced Sensors Ltd
OIW-EX Series of Oil in Water Analyzer Systems. These analyzers are designed to conform to EN61010-1 2001 Part 1 and
are for use within Hazardous Areas to analyze the residual hydrocarbon content in Produced Water. The OIW-EX Series
is certified to the following specifications:

ATEX Directive (94/9/EC) Ex ll 2 G Ex d/de llB T4

Class I Div.1 Groups C & D T4 (USA and Canada)

Class I Zone 1 AEx/Ex d / de IIB T4 / T3 (USA and
Canada; inc. Dual Seal Range)
The analyzer software is MS Windows based for ease of use. Industry standard outputs available include: 4-20 mA
signal to output measurements over a configurable range and an Ethernet port over which the user can either receive
data or remotely control the unit. For complete listing of specifications see Appendix 1 page 87.
The oil content is measured using a technique known as Laser Induced Fluorescence (LIF). A laser penetrates through
the process water causing oil droplets to fluoresce. The resulting oil fluorescence value is used to calculate the
proportion of hydrocarbons in the water.
Contamination of the optical path, a result of oil adhesion, is a common problem with oil in water analyzers. To
overcome this problem a proprietary ultrasonic self-cleaning system has been incorporated into the analyzer which
operates at configurable intervals to accommodate the variable environmental conditions.
