    This process is referred to as "wet-down testing" because the SF6 has higher moisture levels compared to the desiccant. Aluminum Oxide sensors usually perform better on very dry gas. Unfortunately the sensor is known for trapping SF6 on its surface, leading to false dry readings.Automation and System Control - Synecom

NH3 is a liquid in nurse tanks, but vapor is formed by friction as it flows through hoses and pipes after leaving the tank. In addition to eliminating most of the vapor, Kiest says the Liquimatic also has more capacity than heat exchangers.Gearing up for the new age of NH3 - at Agriculture.com
