Product catalog summary

Overview
The BARTEC BENKE Vapor Pressure Process Analyzer (RVP-4) is designed for measuring the vapor pressure of petroleum products, hydrocarbons, and chemical products online and automatically. It is available in three layouts for different applications: fuels, high viscosity liquids, and liquefied petroleum gases (LPG).

Certifications and Compliance
The RVP-4 is ATEX, CSA, and GOST certified, ensuring compliance with international safety standards. It adheres to ASTM D 5191 and DIN EN ISO 13016-1 standards, correlating with several other ASTM methods.

Special Features

Rugged and precise measuring cell design.
Short reaction times with integrated temperature control.
Dry measuring cell eliminating the need for an oil bath.
Wide range of inlet temperatures without additional pre-conditioning.
Low sample consumption and applicable for highly viscous samples.
Available communication interfaces include Modbus/RTU, Modbus/TCP, and remote access options.
Integrated failure diagnosis and self-monitoring capabilities.

Technical Specifications

Measuring range: Standard up to 1.6 bar, optional up to 16 bar.
Repeatability: Typically 1.5 mbar.
Measuring cycle: Discontinuous, typically 7 minutes.
Electrical: Nominal voltage AC 230 V, 500 W power consumption.
Ambient conditions: Operates between 5 to 40 °C and 5 to 80% relative humidity.
Sample quality: Filtered to 10 µm, max moisture content 500 ppm.

Utilities and Connections

Instrument air consumption: Minimum 1.4 Nm³ per flushing cycle.
Coolant consumption: Approx. 20 to 40 l/h for re-cooling.
Signal outputs: Analog and digital outputs for vapor pressure and system alarms.
Control unit: Industrial PC with Windows XP® and PACS control software.
Connections: Swagelok® pipe fittings, optional fittings available.

Additional Options

Optional signal outputs and inputs for validation cycles and stream selection.
MODBUS interface for remote access and communication.

Important Notice
The RVP-4 is subject to continuous product improvement, and specifications may change without notice.

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...
