The first true solution for phase separation monitoring
The Veeder-Root Phase Separation Floats provide you with early detection and continuous monitoring of in-tank phase separation and delivers alarms to your Veeder-Root Automatic Tank Gauge (ATG) to help prevent the pumping of phase separation product into your fueling system.
The earliest detection of phase separation available
The Veeder-Root Phase Separation Floats offer the earliest possible detection of phase separation, saving money and reputations. The Phase Separation Floats interact with multiple densities to detect water and phase separation in any gasoline storage tank containing up to 20% ethanol (E20), making sure you are protected under all circumstances.
The Phase Separation Float Kits replace the traditional gasoline float kit and is compatible with existing Veeder-Root ATGs. The float kits also work in pure gasoline with better performance for water detection than existing float kits by having a lower minimum detectable water height, allowing site operators to quickly respond to a potential problem.
Phase-Two™ Separation Float System
Ethanol Usage is on the Rise, and Subsequently so is Phase Separation
Today, over 90% of U.S. gas stations are blending their gasoline with ethanol. Industry standard water floats operate under a principle of density. They are tuned to detect water at the bottom of a tank. However, the density of phase separation is lower than water, and thus traditional water floats will not reliably detect phase separation. Veeder-Root’s Phase-Two Separation Float System uses multiple densities to detect both water and phase separation, making sure you are always protected.

What are the implications of phase separation?
Ethanol is on the rise, and subsequently so is phase separation - over 90% of U.S. gas stations are blending their gasoline with ethanol, and the number is only rising. Detect phase separation before it impacts your business.
