IQ+FLOW® digital mass flow/pressure meters and controllers for gases are one of 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).

efore installation, make sure that the test pressure is in accordance with
ormal safety factors for your application. If there is no Pressure Testing
ticker on the device or if the test pressure is incorrect, the instrument
hould not be mounted in the process line and be returned to the factory.

ecommended too. Be aware of the pressure drop caused by using filters.

nstrument in up- or downward position make sure to “zero” the instrument
rior to use (see step 10). Avoid installation in close proximity of mechanic
ibration and/or heat sources. The housing of the instrument is according to
lass IP40, which means that the instrument is suitable for indoor (dry)
pplications, like laboratories or well protected (OEM) housings.
low direction is indicated on the body of the instrument. If applicable follow the guidelines of the supplier of the
or leak tight installation of compression type fittings make sure that the tube is inserted up to the shoulder in the
itting body and that no dirt or dust is present on tube, ferrules or fittings. Tighten the nut finger tight; while
olding the instrument, then tighten the nut one turn.
ighten the 10-32 UNF fittings according to the instructions of the supplier
f the fittings.
nly use 1/16” tubing with a straight and clean cut without burrs to ensure
eak tightness. Preferably deburr the tubing prior to installation. A new
errule connection must be made for each new adapter to ensure leakightness and minimum dead volume, due to variances in the adapter
imensions.
or downported instruments make sure that the seals are present at the bottom, that the surfaces are undamaged
5. Leak check
Check the system for leaks before applying pressure. Especially if toxic or other dangerous fluids are used!
6. Electrical connection
Electrical connections must be made with a standard cable or according to the IQ
+
FLOW® hook-up diagram. These
diagrams can be found on the “Documentation and software tools” CD-ROM and at the download section of
www.bronkhorst.com. IQ
+
FLOW® instruments are powered with +15…+24 Vdc.

sing the micro-switch on the instruments, several actions can be monitored
nd started. The green LED is used for status indication. The red LED is used
or errors/warnings/messages. The micro-switch can be used to start several
ctions, such as auto-zero, restore factory settings and bus-initialisation
ctions, if applicable. See specific zero-procedure below and section 3.3 of
he Instruction Manual for more details.

elect the communication type and Baud rate with the “COMM. TYPE”
witch. Select the node address with the “MSD” and “LSD” switch (e.g. MSD
and LSD = 9 selects node 19 for channel 1, but also node 20 and 21 for
hannels 2 and 3). See section 3.3 of the Instruction Manual for more details.
Unless specified otherwise, the IQ+FLOW® instrument is set for RS232 communication at 38k4 baud on node
address 03 by default.
Warm-up time:
Let the IQ
+
FLOW® warm-up for at least 30 minutes for best accuracy.
Do not apply pressure until electrical connections are made. When applying pressure to the system, avoid pressure
shocks in the system and increase pressure gradually. Also decrease pressure gradually when required.
9. Purging
In systems for use with toxic or other dangerous fluids, purging for at least 30 minutes with a dry, inert gas (like
Nitrogen or Argon) is absolutely necessary before use. After use with toxic or other dangerous fluids, complete
purging is also required before exposing the system to air.
10. Zeroing (optional)
The zero point of each instrument is factory adjusted. If required the zero point can be re-adjusted over RS232 or
by means of using the micro-switch. Procedure for zeroing by-micro switch (not for pressure meter/controller):
Warm-up, pressure up the system and fill the instrument according to the process conditions.
Make sure no flow is going through the instrument by closing valves near the instrument.
The setpoint must be zero.
Press micro-switch and hold it. After a short time the red LED will go ON and OFF, then the green LED will go ON.
At that moment release the micro-switch.
The zeroing procedure will start at that moment and the green LED will blink fast. The zeroing procedure waits
for a stable signal and saves the zero. If the signal is not stable, zeroing will take long and the nearest point to
zero is accepted. The procedure will take approximately 10 seconds.
When the indication is showing 0% signal and the green indication LED is burning continuously again, the zeroing
action was successful.
Ready
Your IQ
+
FLOW® instrument is now ready for operation.
