Reid Vapor Pressure (RVP) testing of gasoline has been designated by the
U.S. EPA as well as State Agencies as the test method to determine the volatility of gasoline. During the spring and summer months, the permissible amount of
RVP is normally lower than during the winter months in order to reduce the volatility of organic compounds (VOC) escaping into the atmosphere.
The Multi-Function Sampling System is designed to obtain gasoline samples from storage tanks ashore or on marine vessels. It enables one to transfer from sampler into suitable sampling container without losing vapor pressure. It consists of a specially designed spring loaded bottom valve and an RVP trip funnel designed to fit the RVP Sampler bottom. This combination allows the transfer of gasoline without losing vapor pressure during the transfer process.
Description of Operation
The operator can choose the type of sampler needed by selecting one of the various tops included in the sampling kit. For example, for running sampling, you would choose the adjustable top. For a zone sample, choose the zone bottom.
The RVP trip funnel is designed to open the spring-loaded bottom of the RVP sampler and decant the liquid sample through an extension nozzle, which extends into the bottom of a sample container, and enables it to be filled from the bottom.
