Bergan Level Alarm, Rising Gauge Stick- TwinStick2

Guard Level® Twin-Stick-2a

Features & Benefits:

The Twin-Stick 2A allows up to three applications in one 8” penetration saving the shipyard and owner money.

This unit gives you both High Level (95%) and Overfill (98%) alarms and 1 meter Rising Gauge stick. It can also be ordered with a 2” UTI pipe and flange for manual gauging.

This provides THREE functions in one penetration. May also be used for asphalt with an upgrade to a 10” ANSI flange. The reduction of deck penetrations allows for a clean barge. This unit is serviceable from the top requiring “no access” to tanks.
