KOBOLD Instrumentation, represented in South
Africa by Instrotech – a
Comtest Group
company
– has launched the KFR line of acrylic body flow-
meters offering the perfect balance between low-
cost, accuracy and range availability. Bridging the
microflow and large flow ranges, this flowmeter
can provide an effective solution to industrial
applications, such as gas analysis and water
app l i c a t i ons .
The KFR oper-
ates on proven
suspended float
system, i.e. the
installation po-
sition is vertical
and the flow is
from bottom to
top. It has a one-
piece acrylic body with PVC or metal fittings for
durability. Large lettering and extra hash marks
make the scale clearly visible and take the guess-
work out of reading flow. Further enhancing read-
ability, the low flow meters offer an inherently
stable float design, while the larger flowmeters
feature a float stabilisation mechanism. In the
larger flow ranges, the stabilisation mechanism
allows a smaller installation footprint at a cor-
respondingly lower price. Most units are offered
both with, or without, needle valves. Accuracy,
value, low cost are three non-mutually exclusive
attributes which are made possible by KOBOLD
KFR flowmeters.

User-friendly mass flow controller
EL-FLOWPrestige is the next generation of Bronkhorst
mass flow meters/ controllers for gases. Nearly all
core components have been redesigned and many
improvements and innovations have been incorpo-
rated. With this new series Bronkhorst introduced
the ‘Differential Temperature Balancing’ technology,
ensuring high accuracy and a superb sensor stability.
New, power efficient micro-processors with innova-
tive multistage control loops have been applied to
achieve enhanced dynamic behaviour.The newmetal
housing is of robust yet compact design. EL-FLOW
Prestige represents a truly ground-breaking shift in
versatility and user-friendliness, featuring an on-board
gas conversion model, various fieldbus options and
customizable I/O functions.The control performance
of EL-FLOW Prestige mass flow controllers is fac-
tory adjusted to swiftly respond to setpoint changes,
without overshoot. Moreover, the controllers are
highly resistant to mechanical shocks and
pressure fluctuations, which may be caused
by other devices consuming gas from the
same source. As an option the mass flow
controllers can be tuned for extra fast flow
response (down to 500 milliseconds) or
extra smooth control, depending on the
requirements of the user’s process. The
dynamic behaviour can also be tuned on
site easily, by adjusting the controller speed
settings via FlowTune, or by using our soft-
ware tool FlowPlot. This free tool can also
be used for device diagnostics or alarm and
counter settings.
