5.3.2 Adapter set
The adapters enclosed help to connect the test specimen to
FlowAnalyser. Minimising dead volume and differences in the diameter of the flow
stream helps to increase the accuracy of measurement. When using the LowFlow
channel, the positive connector of the differential pressure sensor is used for pressure
measurements. With the tee enclosed and the connecting tube the relevant ports can
be connected to one another.
5.3.3 Flow Low
3
The Flow Low connector is used for measuring small flows. For calculating the venti-
lation parameters in this measurement channel the trigger must be set to "Pediatric"
(8.3 Standard trigger values). The positive connector of the differential pressure
sensor will then be automatically used for pressure measurements. To connect the
two ports the tee can be used with the connecting tube from the adapter set.
Flow Low
Measuring range: -20 – 20 nL/min
Accuracy: ± 1.75% of reading or ± 0.05 nL/min
The measurement channel of Flow Low does not have any additional
sensors for temperature, air humidity or oxygen concentration. For
flow calculation the current readings are transferred from the
Flow High channel. For accurate measurements it therefore makes
sense to connect the Flow Low channel to the Flow High channel
using a tube. As a result the missing values can be measured.
For flows above 20 nL/min measurement in the low flow channel is
not accurate enough.
