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 Ateco 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 Ateco Gauge Pole Float Basin should be considered as part of a complete solution to make the gauging process simpler, cleaner and more efficient.
