ASTM compliance Customized solutions ATEX, CSA, GOST certified Network and Fieldbus communication Process Analyzer Vapor Pressure Process Analyzer RVP-4

Vapor Pressure Process Analyzer RVP-4 Application The BARTEC BENKE Vapor Pressure Process Analyzer (RVP-4) measures the vapor pressure of petroleum products, hydrocarbons, chemical products and components online and fully automatic. Three layouts are available: ■ Fuels as gasoline or similar products ■ HiVisc for high viscosity liquids ■ LPG Liquefied petroleum gases and similar products others on request YOUR competent Special Features ■ Rugged design of measuring cell ■ High precision and maximized performance due to optimized assembly of measuring cell ■ Short reaction times due to integrated...

Norms and Standards ■ ASTM D 5191 ■ DIN EN ISO 13016-1 Correlates with: - ASTM D 4953 (DVP) - ASTM D 323 (RVP) - ASTM D 5482 (Mini Method Atmospheric) - ASTM D 6377 (VPCR) - ASTM D 1267 (LP Gas) - ASTM D 6897 (LPG Expansion) Method The vapor pressure detection of the RVP-4 is based on the single expansion method. A piston is moved backwards drawing a sample of known volume into a temperature-controlled chamber. After sealing the chamber the volume is expanded by further piston movement until liquid and vapor volume have a ratio of 1 : 4. As soon as the pressure in the chamber has stabilized the...
