O-ring: FMVQ
Flange: Material corresponds to AISI 316/316L and EN 1.4401 /1.4404
Still-pipe dimensions
5-, 6-, 8-, 10- or 12 in.
Tank connection
5 in. hole pattern according to ANSI 5 in. Class 150
6 in. hole pattern according to ANSI 6 in. Class 150 / DN 150 PN 16
8 in. hole pattern according to ANSI 8 in. Class 150 / DN 200 PN 10
10 in. hole pattern according to ANSI 10 in. Class 150 / DN 250 PN 16

Low Loss Mode
To get the accuracy, required for custody transfer bulk liquid storage applications, the
antenna uses Low Loss Mode technology, invented for Rosemount Tank Gauging
products, to transmit radar waves in the still-pipe center.
This virtually eliminates signal and accuracy degradation due to rust and product deposits
inside the still-pipe.
