Pressure seal
The pressure seal includes a double-block function, consisting of a PTFE seal and a fire-
proof ball valve. A pressure sensor enables correction due to vapor for best measurement
performance.

A patented reference device function enables measurement verification with the tank in
service. A verification pin mounted in a still-pipe hole, and a deflection plate with a
verification ring at the lower still-pipe end provide reference echoes at fixed pre-defined
distances.
