The measuring principle is identical to the worldwide used laboratory instruments MINIVAP and therefore the MINIVAP ON-LINE produces equivalent results.Up to 2 different sample streams can be connected to one single analyzer. It is the only available process vapor pressure tester that fully complies to the industry relevant ASTM standards for gasoline (ASTM D6378), crude oil (D6377) and LPG (D6897).
The unmatched accuracy makes refineries save thousands of Dollars each day! Applications The measuring principle is based on the triple expansion method of Grabner Instruments´ worldwide approved and accepted laboratory vapor pressure tester for gasoline and crude oil: MINIVAP VPS. The US-EPA declared MINIVAP the official reference instrument for the USA in 1993.
With MINIVAP ON-LINE, the vapor pressure of gasoline (D6378 / D5191), crude oil (D6377 / D323), liquid petroleum gas (D6897 / D1267) and the vapor-liquid ratio temperature of gasoline (D5188) can be determined. With possible connection of up to 2 different sample streams, these measurements can be performed with one single instrument.
