RF3 Rapid Flash System

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.
