Vapor pressure analyzer RVP-4

Vapor pressure analyzer RVP-4
Manufacturer:
ЭКОХИМПРИБОР

Анализатор RVP-4 выполнят поточные циклические измерения давления пара в автоматическом режиме в предварительно откалиброванном диапазоне измерений для анализа топлива, неочищенной нефти, сжиженных газов или подобных продуктов. Допускается направлять в поточный анализатор два потока пробы и один калибровочный поток. Анализатор предназначен для отслеживания качества процесса, а также контроля технических характеристик и нефтехимических продуктов.

The RVP-4 analyzer will perform in-line cyclic measurements of vapor pressure in automatic mode in a pre-calibrated measuring range for the analysis of fuels, crude oil, liquefied gases or similar products. It is allowed to send two sample streams and one calibration stream to the in-line analyzer. The analyzer is designed to monitor the quality of the process, as well as control the technical characteristics of petrochemical products.

Characteristics

  • Robust measuring cell design
  • Minimum maintenance due to the absence of an oil bath and pumps
  • Sample temperature from 0 to 50 ° С
  • Suitable for highly viscous samples
  • Low sample consumption (2 - 10 l / h)
  • Cooling of the Peltier element with a sample or a cooling liquid
  • Built-in self-diagnosis and troubleshooting system
  • Validation system (optional)
  • Freely programmable digital and analog inputs

Available communication protocols:

  • Modbus / RTU, Modbus / TCP (bidirectional)
  • Remote access via Ethernet (VDSL or FOC is)

Definition:

  • Vapor pressure of liquid fuels in a closed cell at 100 ° F (37.8 ° C).
  • The piston delivers a predetermined sample volume to the thermostatted cylinder. The temperature is regulated by an integrated controller.
  • After the valve closes the cell, the vapor to liquid ratio is adjusted to 4: 1 (single expansion method).
  • The value is fixed when the pressure stabilizes and the equilibrium phase begins. (vapor pressure according to the "micro method").
