Various regulatory agencies require that slotted gauge poles be equipped with emissions control devices. Improperly sealed gauge pole wells can account for as much as 25 times the emissions of an entire seal system. The HMT Gauge Pole Sleeve effectively separates the vapor space in the gauge pole well from the gauge pole interior, preventing these vapors from escaping up the gauge pole. Additionally, the liquid surface area within the gauge pole itself is displaced by the Gauge Pole Float. The combined system effectively reduces a large evaporative surface (and potential source of emissions) area down to a few square inches around the float.

Some jurisdictions may require the use of both the Float and Sleeve. If a float is used, the HMT Gauge Pole Float Basin should be considered as part of a complete solution to make the gauging process simpler, cleaner and more efficient.

For a complete guide pole emissions con­trol system that is maintenance-free with a long service life, choose the HMT Gauge Pole Float and Sleeve.

Key Benefits
The HMT Gauge Pole Float and Sleeve key benefits are:
• Product compatibility — stainless steel components are resistant to all stored products
• Abrasion resistant materials — PTFE liners and wiper materials are abrasion resistant and compatible with all stored products
• Long service life — constructed of materials that last (stainless steel and PTFE)
• Maintenance-free operation — workhorse design and materials
• In-service install — no hot work required
• Can be installed on any floating roof — can be installed on both EFRs and IFRs

Key Design Features
• Low-profile, stainless steel sleeve sized to fit specific tank well and floating roof dimensions (18” - 36” in overall lengths)
• Stainless steel float contains a 10-mil Teflon® wiper and is designed to operate in specific gravities ranging from 0.60 to 1.00
• 25-mil Petroflex PTFE (Teflon®) liner and pole wiper provide excellent chemical compatibility and abrasion resistance while effectively closing slots in the gauge pole, eliminating vapor emissions loss
• Easily installed while tank is in service
• Constructed of maintenance-free materials
• Optional basin to eliminate messes from the Gauge Pole Float
