Mobile measurements
As you see, the VSM-02 is very handy. To perform a measurement it is connected
with two pressure hoses to the nozzle, which is inserted in the line system to be inspected.
The device is supplied with a stable transportation case, which contains all necessary parts,
such as nozzle, pressure hoses, cables and so on. This makes it possible to
accomplish a lot of measuring tasks directly in place near the machinery and
equipment which is to be checked. Typical tasks are, e.g., the performance control
of compressors, the sealing quality of tools, measurements of efficiency,
inflation degree and much more.
Since portable Windows-PCs became omnipresent working tools in the late 1990s,
the VSM-02 has been deliberately designed to take special advantage of being operated with a PC.
There are several additional measuring and convenience
features available. When connected
to a PC, the VSM-02 can, for instance, be operated at a much higher
measuring
cycle rate than in normal mode. The measured values are graphically displayed on the
screen and can lead to interesting insights about short, dynamic processes in the
pressure line. The extended features are explained in more detail in the
software
section.
Quite a number of our customers let several measuring nozzles permanently installed.
Since an appropriate nozzle causes virtually no pressure losses (see also
measuring
principle), this is perfectly ok. They install the nozzles at important junction points
and use one VSM-02 to
sample the volume flow. For this
purpose the measuring
device is equipped with a mechanical protection which makes it possible to connect the
device to nozzles and lines under full working pressure. With
the built-in quick release
couplings a sample measurement is a matter of no more than a
few seconds. Naturally the
measurement does by no means impair the normal work or the
supply of downline consumers.
