Compartmentalized• The gauge head is split into two seperate

compartments: the sealed side and the open side.• The sealed side is exposed to the tank; the open

side exposed to atmosphere. • Sealed side features integral sloped channel,

allowing condensation to drain freely back into the tank.

• Compartments are only mechanically connected by the bearing-supported axle, and sealed by the unique Dual Dry Seal.

Dual Dry Seal• Dual dynamic FKM (Viton) seals the compartment

from each other and prevents emission from the tank escaping from the gauge head.

• Dry-Seal technology requires no addition of grease or other sealing agents for long-term reliable operation.

Large Diameter, Indexed Cable Reels• Cable is wound on two reels, one in each

compartment.• Large Diameter Reels provide require minimal

actuation forces.• Reels are connected mechanically via a keyed

common axel.• Reels provide acurate cable indexing with none of

the slip associated with pulley systems.• Indexed reels allow the use of the bolt-on Goshawk

Level Transmitter.
