Level Gauging and Sampling Nozzles for Tanks
PROTEGO® Gauge Hatches Types PF/K, PF/TK, and PS/KF are used as lockable gauge nozzles which are only opened for gauging or sampling. Otherwise, they are tightly closed. The Gauge Hatches PROTEGO® PF/K, PF/TK, and PS/KF mainly consist of housing Corps A housing is a solid shell, which surrounds a content, either protecting the content from external influences, or protecting the environment from the content. , gauging nozzle lid Couvercle de manchon d'évaluation The gauging nozzle lid is part of the gauging nozzle. , and gauging nozzle bracket Étrier de manchon d'évaluation The gauging nozzle bracket is part of the gauging nozzle. . The housing is equipped with stainless steel gauging marks as standard. In the pedal-operated version PROTEGO® PF/TK, the gauging nozzle pedal Pédale de manchon d'évaluation The gauging nozzle pedal is part of a gauging and sampling nozzle with foot pedal operation. is connected to both the housing and the bracket.

Flange connection type
The flange Connection is to EN 10692-1, Form A. Optionally, the Connection flange can be made according to any international standard.Design Types and Specifications
Depending on the intended use the following designs are available:Gauge hatches for welding to the tank are available as types PROTEGO® PS/K and PS/TK. A separate data sheet is available.
Gauge Hatches can for instance be used in combination with the Manual gauge devices type PROTEGO® H/P or wih the gauging and sampling device PROTEGO® VP/HK.
Gauge Hatches can be applied on tanks with floating roof Toit flottant A floating roof is the roof of a tank that is fitted with floating chambers (pontoons) and lies on top of the liquid. .
