ERAVAP ONLINE Process Vapor Pressure Tester

ASTM D6377, ASTM D6378, ASTM D6897

Tests vapor pressure of gasoline and LPG, TVP and bubble point of crude oil. The ERAVAP ONLINE uses the leading-edge Piston-based measurement principle for vapor pressure testing. The built-in piston renders a vacuum pump obsolete and simplifies measurement. The high-durability instrument includes maintenance-free, self-lubricating gears and the continuously monitored lubrication of the piston. Since ERAVAP ONLINE measures according to the latest vapor pressure standards and its measurement cell is based on eralytic's laboratory systems, results from ERAVAP ONLINE are identical to laboratory results. There is no need for correlating results.

Common Applications include:

  • Quality control at terminals or refineries
  • Monitor both inlet streams and blended streams
  • Blending naptha into viscous crude
  • Blending butane into gasoline
  • Vapor pressure of gasoline, LPG, TVP
  • Bubble point of crude oil

  • Remote control software
  • Built-in Quality Control tracking
  • Up to 4 sample streams per analyzer - use for samples, quality control, cleaning for crude oil
  • Spare Measurement cell minimizes downtime
    • one measurement cell is cailbrated and maintained, the second is used for measurements
    • cells can be swapped in less than a minute

Piston-Based Measurement

  • renders vacuum pumps obselete
  • simplifies measurement

High Durability

  • 24/7 non-stop operation
  • Maintenance free, self-lubricating gears
  • Housings meet requirements for hazardous materials

Lab-Grade Performance

  • no need to correlate results
  • outperforms standard methods in terms of repeatability and reproducibility
