High Level Switch for Floating Roof Tank

[controlnovice]

Any good experiences with high level switches for floating roof tanks?

Found OMNTEC VersaLevel, Mobrey, Magnetrol, and a few others, but have no experience with them.

Any recommendations?

Consider avoiding discrete signals for the device. Instead consider the analog level signals then digest the signals for alarms within the control and perhaps shutdown systems. Consider dual signals - often with different technologies. Such plans could separate operation modes from trip modes and apply different errors due to density, temperature, fouling errors etc.

Have analog already. Looking for that secondary/last ditch signal.
