5.1.3 Principle of Operation for
Flow Measurement
The Flow is measured over a differential pressure
measurement in the flow channel. A screen is used as the
restrictor.
: dynamic viscosity of gas [Pa s]
: density of gas [kg / m3]
c1, c2: device specific constants (channel geometry)
Dynamic
Viscosity
• The viscosity of a medium is its
resistance to shear or flow
• The viscosity is strongly temperature
dependent
• Small dependency on humidity and
pressure
Density
• The density is a measure of the
medium's mass per unit of volume
• The density is strongly temperature and
pressure dependent
The dependence on the ambient conditions is the reason
why the flow is sometimes transferred to standard
conditions (>5.2 Standard Conditions for Flow
Measurement).

6.3 Mechanical
Connections
6.3.1 Protection Filter
In order to protect the instrument from contaminations with
particles of the air it is important to use the filter, which is
delivered with each instrument. The filter has to be used on the
High flow as well as on the Low flow channel.
6.3.2 FlowAnalyzer
TM
Adapter Set
The FlowAnalyzer
TM
Adapter Set included assists in connecting
various test objects to the FlowAnalyzer
TM
. A minimal amount of
dead space as well as minimal differences in the Flow stream
assist in assuring highly accurate measurements. When using
the Low flow connection for measuring respiratory parameters,
the positive interface of the differential pressure sensor is
used for the pressure measurement. The T-Piece included with
the connection tube connects the corresponding interfaces.
and result in inaccurate measuring results. The Filter must be
checked on a regular basis.
Particles in the air may clog the measuring system
Page 17 / 84
6.3.3 Low Flow2
The Low flow connection is used to measure small flow rates. In
order to calculate respiratory parameters using this measurement
channel, the trigger must be set to “infant”. Thereby, the positive
interface from the differential pressure sensor will automatically be
used as the pressure sensor. The T-Piece with the connection tube
can be used to connect these two interfaces.

Low flow
USER MANUAL FLOWANALYZER
TM
There are no additional sensors in the low flow
channel to measure temperature, humidity, or O2
concentration which have an impact on flow measurement.
To achieve very accurate measurements it helps if the back
end of the low flow channel is connected to the high flow
channel. On this way the additional values can be measured.
For Flows higher than 20 sl/min the measurement is not
accurate anymore.

When working with higher humidity it is important
that there is no condensation inside the instrument. Water can
destroy the sensors!
Pressures higher than 500 mbar will destroy the sensors!

6.3.5 Differential Pressure
The Differential pressure connections can be used to measure
differential pressure.
Range:
± 150 mbar
Accuracy:
± 0.75% of reading or ± 0.1 mbar
6.3.6 Low pressure (PFC-
3000L)
There is an additional low pressure sensor for the PFC-3000L.
The sensor is connected to the specified connector and is
marked with a blue ring.
Range:
0...5 mbar
Accuracy:
± 1% of reading or ± 0.01 mbar

remaining connector where as the second port of the sensor
is measuring against ambient. The measurement range
remains the same.

There is an additional pressure sensor ± 1 bar for the PFC-
3000V. The sensor is connected to the specified connector and
is marked with a red ring.

6.3.8 High Pressure
The High pressure connection can be used to measure
pressures greater than 150 mbar.
If you prefer for this connection a DISS O2 Connection, there is
an appropriate adapter available.
Range:
0...10 bar
Accuracy:
± 1% of reading or ± 10 mbar

When measuring below 150 mbar it is
recommended to use the Differential Pressure port
± 150 mbar since the accuracy is up to 100 times higher.
Pressures higher than 15 bar will destroy the sensor!

6.4 Electrical Interfaces
6.4.1 USB
The USB interface is used to connect the FlowAnalyzer
TM
to the PC. The connection is located on the back of the device.
If FlowLabTM software was supplied with the device, the
recorded values can be graphically displayed on the computer.
If your device does not have this software, the USB connection
will be blocked. It can be released at any time with a clearance
code (> 8.2 USB Communication).
6.4.2 RS 232
The RS232 interface is used for servicing (firmware download),
for the connection of the MultgasAnalyzerTM MGA-3050 as well
as for remote control of the unit and is located on the back of the
FlowAnalyzer
TM
.
The connection to the RS 232 port has to be established over
the special RS 232 interface cable.
If the instrument has to be remote controlled e.g. through a
specific software package you can ask your authorized dealer for
a detailed description of the protocol.
