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 Floating roof A floating roof is the roof of a tank that is fitted with floating chambers (pontoons) and lies on top of the liquid. .
