12.5 Simulated Test
This setting can be used when there is no flow available but communications need
to be tested.
12.6 Low Flow Alarm Disabled (Clean Systems)
•
The ICM uses the width of the pulse to derive flow, its flow output is only an
indication, intended for installation guidance.
•
It is worth reinforcing that the primary function of the product is to produce a
measurement of cleanliness, and not act as a flow meter. If the unit produces a
contamination measurement, then the flow rate is sufficient enough for it to do
so.
•
The ICM needs particles to pass through the flow cell to calculate flow, the
dirtier the system is, the more statistically accurate the flow output becomes.
•
Conversely, when placed on a very clean system it can have difficulty in working
out the 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 a lower confidence or no indication at all on a clean system. If this is the
case the tick box is available to allow a contamination reading. Note: Should
the flow alarms be disabled at any point, it is imperative that the ICM is installed
in such away that if the system is shutdown (zero flow) the ICM is also shutdown
so as not to measure stagnant fluid and provide erroneuos readings.
•
It may be necessary that the low flow indicator is turned off if filtration is below
10um (ISO 14/12/10 (NAS Class 4)).
12.7 Continuous Testing
In the Continuous Testing area are settings which control how the ICM decides
when to perform and log a test. Selecting Test Continuously makes the ICM auto-
matically repeat the test, according to the specified Test Interval . Setting an interval
longer than the test duration results in the test being repeated upon each expiry of
that interval. For example, setting a Test Duration of 1 minute, and a Test Interval
