Leak detector Vakumatik IVF R34
4. Type / intended use
The functional principle of the vacuum leak detector type Vakumatik IVF R34 (low pressure)
with integrated pump is assessed as a Category 1 device pursuant to DIN EN 13160-2:2003.
The device is exclusively designed for installation in vacuum leak detection systems at
double-walled tanks or single-walled tanks with leak protection lining storing liquids
hazardous to water with a flash point >55°C. The leak detector unit must not be installed in
explosive area.

5. Area of application
5.1.
General
-
Use only in applications with a suction line connected to the bottom of the
tank.
-
The tank may only be operated at ambient pressure condition.
- The interstitial space may not contain any leakage liquid.
- The leak detector may only be assembled outside an ex-zone.
- The requirements and conditions mentioned in the respective reports, standards and
qualifications of the tanks / leak protections lining or interstitial spaces must be fulfilled. This
is also applied to the application limits with regard to the density of the stored liquid.
- The interstitial spaces must be suitable for the respective alarm vacuum P
AE
and for a max.
vacuum in interstitial space P
PA
.
- The specific regulations of the approval certificate of the leak detector have to be observed.
5.2. Single walled containers / tanks with a leak protection lining
- Interstitial space of single walled containers in accordance with DIN 6608, EN 12285-1, DIN
6616 Form A, EN 12285-2, DIN 6619, DIN 6623, DIN 6624 part 2, DIN 6625 and with an
approved flexible or fixed leak prevention lining, approved for connection with the leak
detector and its switing values (see 4.1).
