What are the advantages of our flow
measuring technology?
1) (YHQXQGHUSUHVVXUHWKHÀRZVHQsor VA 500 is mounted by means of a
standard 1/2“ ball valve. During mounting
and dismounting the safety ring avoids
an uncontrolled
ejection of the probe
which may be caused by the operating
pressure.

For the mounting into different pipe
diameters VA 500 is available in the following probe lengths: 120, 160, 220, 300,

into existing pipelines with inner diameters
of 1/2“ upwards.
safety ring
The exact positioning of the sensor in the
middle of the pipe is granted by means of
the engraved depth scale. The maximum
mounting depth corresponds with the resprective probe length. Example: VA 500
with probe length 220 mm has a maximum mounting depth of 220 mm.
2) If there is no suitable measuring site
with a 1/2“ ball valve present there are two
simple possibilities to set up a measuring
point:
A Weld on a 1/2“ screw neck
and screw on a 1/2“ ball valve
B Mount spot drilling collar incl.
ball valve (see accessories)
By means of the drilling jig it is possible
to drill under pressure through the 1/2“
ball valve into the existing pipeline. The
GULOOLQJFKLSVDUHFROOHFWHGLQD¿OWHU7KHQ
the probe can be mounted as described
under point A.
3) Due to the large measuring range of
the probe even extreme requirements
to the consumption measurement (high

be met. The measuring range is depending on the pipe diameter - see table on the

work according to the approved calorimetric measuring principle. An additional
pressure and temperature compensation is not necessary. Contrary to the
82
previously used bridge circuit the newly
developed evaluation electronics records
all measured values digitally. This enables
very precise and fast measurements. Due
to the new evaluation electronics all VA
520 have an integrated Modbus output
as a standard. So all parameters can be
transferred via Modbus.
Due to its compact design it is possible to
monitor all compressed air systems from
the compressor to the smallest compressed air tool (1/4“ to 3 inch) with the

other gases like e.g. nitrogen, oxygen and
CO2 can be
measured.

soiled. In case of compressed air meters
with integrated measuring section the
„measuring device“ cannot be removed.
For this reason an expensive bypass
line is necessary. The design of VA 520
enables the removal and cleaning of
the „measuring device“ with e.g. soap
water without any dismounting of the
measuring section. A closing cap grants
a continuous use of the line for the duration of the cleaning. A bypass line is not
necessary. The alignment pin grants an
accurate installation of the measuring
