a. Mount/install instrument properly
·
For IQ+FLOW® the upright position is preferred. When mounting an
instrument in a vertical position (flow going upward or downward),
zeroing of the instrument is advised (see step 10).
·
The housing of the instrument is according to class IP40, which means
that the instrument is suitable for indoor (dry) applications, like
laboratories or well protected (OEM) housings.
Mount the instrument in the line in accordance with the flow arrow on the instrument body. If applicable, tighten
fittings according to the instructions of their supplier. Special types of fittings are available on request.
Avoid installation in close proximity of mechanic vibration and/or heat sources.
b. Compression type fittings
For leak tight installation of compression type fittings make sure that the tube is inserted up to the shoulder in the
fitting body and that no dirt or dust is present on tube, ferrules or fittings. Tighten the nut finger tight; while holding
the instrument, then tighten the nut one turn.
c. 10-32 UNF fittings
Tighten the 10-32 UNF fittings according to the instructions of their
supplier.
Only use 1/16” tubing with a straight and clean cut without burrs to ensure
leak tightness. Preferably deburr the tubing prior to installation. A new
ferrule connection must be made for each new adapter to ensure leak-
tightness and minimum dead volume, due to variances in the adapter
dimensions.
d. Mounting downported instruments
For downported instruments make sure that the seals are present at the bottom, that the surfaces are undamaged
and that they are dry and free from dirt or dust.

Leak check
Check the fluidic system for leaks before applying pressure, especially when using hazardous media (e.g. toxic or
flammable).
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
www.bronkhorst.com/downloads. IQ+FLOW® instruments are powered with +15…+24 Vdc.

a. Analog/local operation (single-channel versions only)
For analog operation refer to the “Hook-up diagram IQ+FLOW®” or use an
RJ45 loose-end cable (7.03.419) to connect the required signals.
b. Digital RS232 operation
Connecting the instrument with an RS232 cable to a PC will enable you to
use the (free) Bronkhorst® software for Windows, such as FlowDDE and
FlowPlot.
See the IQ+FLOW® manual (document number 9.17.045) for further
explanation on RS232 operation of the IQ+FLOW®.
