SCOPE OF THIS GUIDE
IQ+FLOW®
Micro Fluidic Mass Flow and Pressure Meters/Controllers for gases belong to the smallest chip based instruments of
its kind.
IQ+FLOW®
mass flow meters/controllers can be applied for measuring and fast control of gas flows up to 5000 mln/min,
for applications with pressure conditions up to 10 bar (145 psi) and temperatures between 5 and 50 °C (41 to 122 °F).
IQ+FLOW®
pressure meters/controllers can be applied for pressure ranges from 0,01…0,5 bar up to 0,2…10 bar. The instruments can either
be operated in analog or digital mode (RS232 or RS485).

Starting up
1
Check functional properties
Before installing the instrument, check if the properties stated on the serial
number label match your requirements:
·
Instrument type
o
gas flow (red label) or
o
pressure (yellow label)
·
Flow rate
·
Fluid to be measured
·
Upstream and downstream pressures
·
Input/output signals
·
Temperature
·
IQ+FLOW® gas flow instruments are designed for dry, clean, non-corrosive gases
·
IQ+FLOW® pressure instruments are designed for dry, clean, non-corrosive, non-flammable gases
Do not use the IQ+FLOW® for other gas types.

Check test-pressure
The tested pressure is stated on the instrument with a red label.
Before installation, make sure that the tested pressure is in accordance with
normal safety factors for your application. If a pressure test label is missing,
or if the tested pressure is insufficient, the instrument must
not
be
mounted in the process line and should be returned to the factory.
3
Check if system piping is clean
For reliable measurement, always make sure the fluid stream is clean.
Use filters to assure a moisture, oil and particle free gas stream
(recommended pore-size: 7 µm).
If back flow can occur, installing a downstream filter and a check valve is
recommended too. For high flow rates, select a suitable filter size, to avoid
a too high pressure drop.
