SCOPE OF THIS GUIDE
EL-FLOW® Prestige
is the next generation of Bronkhorst® Mass Flow Meters/ Controllers, using the latest, highly accurate,
thermal bypass sensor technology and featuring excellent control characteristics. Thanks to the advanced sensor technology in
combination with a state-of-the-art printed circuit board, the instruments feature improved long term stability as well as an
unsurpassed temperature stability. The optional Pressure Insensitive functionality offers real-time pressure compensation
ensuring additional accuracy and reliability under varying inlet pressure conditions. Furthermore, due to a power efficient
microprocessor, the power consumption of the instrument is reduced. The mass flow meters and controllers can be supplied in
full scale ranges from 0,7 ml
n
/min up to 100 l
n
/min Air-equivalent at max. 64 or 100 bar (1000 or 1500 psi) pressure rating.

Starting up
1
Check functional properties
Before installing the instrument, check if the properties stated on the
instrument label match your requirements:
Flow rate
Fluid to be measured
Up- and downstream pressures
Input/output signals
(see also step 6)
Temperature
Valve type
(N.C. - Normally Closed / N.O. - Normally Opened)
2
a. Check test-pressure
The tested pressure is stated on the instrument with a red sticker.
Before installation, make sure that the tested pressure is in accordance with
normal safety factors for your application. If a pressure test sticker 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.
b. Sealings
EL-FLOW® Prestige
instruments are equipped from factory with sealings compatible with the requested gas type.
However the instruments have Multi Gas / Multi Range functionality on board. If another gas or mixture is used,
always make sure that the gas/mixture is compatible with the installed sealing materials. Refer to the EL-FLOW®
Prestige manual (document no. 9.17.084) for a compatibility list.

c. Ambient conditions
EL-FLOW® Prestige
instruments are suitable for use in conditions between -10…+70
°
C and relative humidity of
10…90 %RH, unless specified otherwise. Please note that
EL-FLOW® Prestige
instruments have an ingress
protection rating of IP40, implying that the electronics housing and electrical connection do not offer any
protection against moist environments.
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: 5 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.
4
Mount/install instrument properly
Mount the instrument in the line in accordance with the flow arrow in the
instrument body. Tighten fittings according to the instructions of their
supplier. The use of Swagelok RS-type stainless steel adapters is advised.
Avoid installation in close proximity of mechanic vibration and/or heat sources.
5
Leak check
Check the system for leaks before applying (fluid) pressure, especially if toxic, explosive or other dangerous fluids
are used.
6
Electrical connection
Electrical connections must be made with a standard cable or according to
the applicable hook-up diagram (see page 2). The factory installed 9-pin
sub-D settings are indicated on the instrument label. Make sure that the
power supply is suitable for the indicated power ratings, indicated on the
instrument label, and that double or reinforced insulation is used for the
power supply.
7
a. Analog/local operation
Connect the
EL-FLOW® Prestige
to the power supply/readout unit using a
cable with 9-pin sub-D connector.
b. Digital RS232 operation
Digital operation over RS232 can be established when using the
following setup. Connecting the instrument with a RS232 cable
or an RS232 cable with a USB to RS232 converter to a PC
enables use of the (free) Bronkhorst® software for Windows,
such as FlowDDE and FlowPlot. Make sure that the instrument
label indicates RS232 settings and apply the proper baud rate
settings. If the instrument is not set for RS232 communication,
please refer to the EL-FLOW® Prestige manual (document no.
9.17.084) for switching to RS232 communication settings.
