Continuous Sampling

6 Continuous Sampling
The Analyser can be selected for continuous testing at set time intervals.
Once continuous sampling has started the PML²’s flush valve automatically opens
and closes before each test. This allows representative fluid to reach the sensing
arrangement before the 15ml sampling test commences. The flush valve automati-
cally opens at the end of the sampling cycle and remains open whilst the analyser is
emptying to waste the sample fluid from the previous test.
Additionally, depending
on the time set for Minutes Between Tests, the Flush valve operates as follows:-
Time set to 0
– At the end of the analyser’s emptying cycle the flush valve auto-
matically closes and the next sampling test immediately starts.
Time set to between 1 and 5
– After the analyser’s emptying cycle has finished
the flush valve remains open for the time set, then
automatically closes before the next sampling test.
Time set to between 6 and 30000
– Flush valve automatically closes after the emp-
tying cycle has finished and remains closed un-
til 5 minutes before the next sample test is pro-
grammed to start.
The servo motor operating the Flush valve exhibits a slight ‘ticking’ noise, both when it is open and
closed. This is normal.
