What is a vapor recovery test commonly referred to as?

The term commonly used for a vapor recovery test is the air to liquid ratio test. This test focuses on ensuring that the vapor recovery system is effectively capturing and returning vapors from the storage tanks during the filling process, thereby preventing excess vapors from being released into the atmosphere.

By measuring the air to liquid ratio, this test evaluates the efficiency of the vapor recovery system, ensuring it is operating within the designed parameters. An appropriate ratio is critical because it indicates proper interaction between air and the liquid entering the storage tank, which is essential for minimizing environmental impact and adhering to regulatory compliance regarding vapor emissions.

Understanding the air to liquid ratio helps technicians diagnose potential issues within the vapor recovery system, which is vital for maintaining operational efficiency and ensuring that the installation meets environmental standards.
