RF3 Rapid Flash

Automated Flash Point Analyzer

Rapid Flash Overview

The Rapid Flash is a microprocessor-based flash point monitoring system. It provides pipeline operations personnel with the capability of automatic product flash point monitoring. The unit can be used locally or remotely for batch interface cutting or transmix injection. Deviations in product flashpoints can be monitored with user-programmable high and low alarm setpoints. Out-of-spec sections of a batch, which would normally reduce the overall quality of the batch, can then be cut out. The system requires approximately 30 seconds to perform a flashpoint reading with a programmable delay between readings from 0 to 9999 seconds. The flashpoint is determined by drawing air through a product sample chamber to develop a gas vapor. This vapor is then passed through a sensor chamber that measures the product’s lower explosive limit (L.E.L.). The sample temperature, L.E.L., and API gravity (API gravity must be supplied to the Rapid Flash as a 4-20 may signal) are then used to calculate the product flashpoint. The system is currently tested for measuring various grades of fuel oil, kerosene, and Type A jet fuel. The flashpoint reading is supplied as a 4-20 ma output signal (scaled 0-250 F or 0-200 F) and can also be displayed on a laptop or tablet computer, either locally at the unit or remotely at the control room. A laptop or tablet computer can also be used to monitor the system operation, configure the system or troubleshoot problems.

Features at a Glance

The RF3 Flash Point features improved reliability and reduced maintenance:

Note: Tests have shown the Rapid Flash automatic inline flash point monitor will produce similar flash points that are comparable to the ASTM D # standard: however, the RF2 is not intended to be used as a laboratory instrument. Nor does it duplicate the accuracy set forth by the ASTM D93 standard.

  • Automatic shutdown and startup with a user supplied status input.
  • Automatic shutdown and startup on product that is out of sensor range. (gasolines, etc.)
  • Redundant sensors with autozero and automatic switchover are now a standard feature.
  • Alarm output on system malfunction.
  • Remote access via Ethernet or optional WiFi
  • Event and alarm logging
  • Flash point and gravity trending
  • Touch screen computer included for monitoring, diagnostics, and configuration.
  • These features and many more make the Rapid Flash a valuable component in the overall scheme of pipeline automation.
