Description

The vapor pressure is an indication of a liquid evaporation rate and relates to the tendency of volatile components to escape from the liquid. To assure safe storage and transportation of petroleum products, minimize environmental pollution and assure proper functioning of combustion engines it is important to measure the vapor pressure.

Application

The BARTEC BENKE Vapor Pressure Process Analyzer RVP-4 measures the vapor pressure of various petroleum products. Due to its design it can be used for gasoline applications as well as for high pressure applications on natural gas liquids. It is also the best choice for applications for viscous samples such as crude oil without the necessity of implementing additional wash cycles. It is also possible to measure the vapor pressure at different temperatures e.g. True Vapor Pressure (TVP) for storage tank application.

High precision and maximized performance due to optimized assembly of measuring cell
Minimized maintenance requirements due to temperature control and insulating system without oil bath/pumps
Wide range of inlet temperatures
Also applicable for highly viscous samples
Low sample consumption
Re-cooling of peltier device by either product or coolant
Available communication interfaces:
- Modbus /RTU, Modbus/TCP (bidirectional)
- Remote access via Ethernet (VDSL or FOC is)
Integrated failure diagnosis and self monitoring
Heat tracing if required
Validation report for quality assurance
Freely programmable digital and analog inputs
