Flow Rate Can be disabled for very clean systems ( No 6 micron particles or smaller)

10. Flow Indication
Because the ICM uses the time between pulse widths to derive flow its flow output is only an indication, intended for installation guidance.
What is worth reinforcing however, is that the primary function of the product is to produce a measurement of cleanliness, and not to act as a flow meter. If the unit produces a contamination measurement, then the flow rate is high enough for it to do so.
Because it needs particles to pass through the flow cell to calculate flow, the dirtier a system is, the more statistically accurate the flow output becomes.
Conversely, when placed on very clean systems it can have difficulty in working out flow due to the very low number of particles passing through the flow cell. This will not effect the contamination measurement, but it is worth noting that customers may experience lower confidence or no indication at all on clean systems. This is why we offer the ability to disable flow on clean system, otherwise the product defaults to not showing a result.
Typically, below ISO 14 we would recommend using this feature.

17. External Relay Alarms Alarms
The ICM has two switched “External relay alarm” outputs that can be used to signal external equipment in various ways, according to the test results and the alarm settings.
There is also a multi-colour front panel light which indicates how the result compares to the set alarm thresholds.
The alarm settings are comprehensive and flexible, allowing the ICM to be used in many different scenarios.

18. Inline Contamination Monitor
All ICM versions have a multicolour indicator on the front panel, which is used to indicate the status or alarm state.
Green indicates that the test result passed, i.e. none of the alarm thresholds were exceeded.
Yellow indicates that the lower cleanliness limit was exceeded,
but not the upper one.
Red indicates that the upper cleanliness limit was exceeded.
Blue indicates that the upper water content limit was exceeded.
Red/Blue Alternating indicates both cleanliness and water
content upper limits exceeded.
Violet indicates that the upper temperature limit was exceeded.
The LED can also indicate various fault codes by turning red
and flashing white a number of times

23. Installation Options

24. Installation Options
Avoid pressure transients of greater than 100 barg.
● For optimum performance we recommend 1 barg differential across the ICM
● Avoid installing the ICM close to pump outlets (In some circumstances pump ripple
can have a effect on particle count)
● For best results a check valve (1 to 2 barg approx) should be installed on the return
line to reduce the risk of air backflow.

25. Inline Contamination Monitor
Each ICM supplied consists of the following:
• ICM particle counter
• Calibration certificate
• ICM user manual (CD or USB memory stick)
• LPA View CD ROM, software package
• LPA View test analysis software manual
• Circular connector pre-wired with 2 m cable

26. Inline Contamination Monitor
A pressure compensated flow control valve specifically designed to fit the ICM. This may be needed if the application produces an oil flow that varies outside the working range of the standard unit(20-400ml/min).

30. Benefits
Saving money on total cost of filtration eliminating unscheduled filter changes
Constant system monitoring = pro-active maintenance = cost savings
Constant system monitoring = trending system cleanliness and moisture levels by utilising system memory data = cost savings (Warranty)
Prolonging major component life due to pro-active maintenance
Save time – high cost processes effectively monitored
Pro-active control – The ICM is the low cost, efficient method of system monitoring when system cleanliness or moisture levels are exceeded
