2.1 VEGASWING
Generally VEGASWING can be mounted in
any individual position. The instrument must
be mounted such that the tuning fork is at the
height of the requested switch point. Note the
following installation instructions:
Transport
Do not hold VEGASWING on the tuning fork.
Especially with flange or tube versions, the
tuning fork can be damaged by the instru-
ment weight. Transport enamelled and
ECTFE-coated instruments very carefully and
avoid touching the tuning fork.
Switch point
The tuning fork is provided with lateral mark-
ings (notches) marking the switch point with
vertical installation relating to the medium
water. Note when installing VEGASWING that
the marking is at the height of the requested
level. Note that the switch point of the instru-
ment shifts when the medium has a density
deviating from water (water = 1,0 g/cm
3 ). The
switch point can be adapted via a potentiom-
eter, to set the switch point to the marking
(notch). With the adjustment 1,0 g/cm
3 a
switch point from a density of ³ 0,7 g/cm 3 is
ensured. For products with a density < 0,7 g/
cm
3 the potentiometer must be readjusted on
the oscillator. Oscillator SWING E82 Z:
0,5 … 1,0 g/cm
3 (see fig. 2.1). The switch
point adaption is described under "4 Set-up “.

Recommended installation position for adhe-

Adhesive products
In 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.
