• The gauge head is split into two separate 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.

Compact, Indexed Cable Reels

  • Cable is wound on two reels, one in each compartment.
  • Compact Cable Reels reduce gauge head size, allow for higher pressure operation.
  • Reels are connected mechanically via a keyed common axel.
  • Reels provide accurate cable indexing with none of the slip associated with pulley systems.
  • Indexed reels allow the use of the bolt-on Goshawk Level Transmitter.
