2.1 VEGASWING
In principle, VEGASWING can be mounted in
any position. The instrument must be
mounted such that the tuning fork is at the
height of the required switching point. Note
the following installation instructions:
Transport
Do not hold VEGASWING by the tuning fork
as particularly with flange or tube versions,
the tuning fork can be damaged by the in-
strument’s weight. T ransport enamelled and
ECTFE-coated instruments very carefully and
avoid touching the tuning fork.
Switching point
The tuning fork is provided with lateral mark-
ings (notches) marking the switching point
with vertical installation for the medium water.
When installing VEGASWING note that the
marking is at the required height. Note that
the switching point of the instrument shifts
when the medium has a density differing from
water (water = 1,0 g/cm
3 ). The switching
point can be adapted using a potentiometer
to set it to the marking (notch). With the ad-
justment 1,0 g/cm
3 a switching point from a
density of > 0,7 g/cm 3 is ensured. For prod-
ucts with a density < 0,7 g/cm 3 the potentiom-
eter must be readjusted on the SWING
E82 C, R, T oscillator as follows: 0,5 … 1,5 g/
cm
3 , oscillator SWING E82 Z: 0,5 … 1,0 g/cm 3
(see fig. 2.1).

Recommended installation position for adhe-
sive products:
Adhesive products
In the case of horizontal mounting in adhesive
and viscous products, the surfaces of the
tuning fork should be vertical to reduce build-
up on the tuning fork (see fig. 2.2). The posi-
tion of the tuning fork is marked by a notch
on the hexagon of VEGASWING. Therefore
you can check the position of the tuning fork
when screwing in. When the hexagon is on
the seal, the thread can be still turned by
approx. half a turn. This is sufficient to reach
the recommended installation position.
