3. Set measured height difference

on the scale using the handwheel (see
OPERATION
).
4. If the density of the operating medium
is greater than 860kg/m³
, a conversion to the
corrected safety height
HA
is required. A higher vacuum is generated in the liquid column
p
o,g
. The density of the stored operating medium must be known. This is shown in Table
below.

If the safety height is not corrected, there is no protection against siphoning.

If the density of the operating medium
is less than 820kg/m³
the setting for the safety height
can be reduced when
HA
has been determined. This is beneficial in case of larger height
differences to reduce the vacuum in the suction line.
