The Water Separation Instrument is a fully automatic and compact bench top / portable instrument. The instrument measures how effectively a fuel sample releases entrained and emulsified water when pumped through a water coalescing filter. The WSI displays the measured water separation index. Results can range from 0.0 to 100.0. A high water separation index, such as 100.0, indicates the test specimen coalesces easily and is relatively free of surfactants.

The WSI is operated via a touchscreen user interface that takes you through the testing procedure. The instrument consists of a sonicator, temperature probe, filter cartridge, dye detector and dyed water, solvent and test specimen pumps.

The latest Product Quality Bulletin (No 121) from JIG revises the Protocol for Water Separation Testing Downstream of Point of Manufacture and now advises testing can be done using ASTM D8073 (IP 624).

Additional Information

Before each test the WSI flushes the instrument with the test specimen, primes the instrument and primes the filter. When the test starts the unit pumps dyed water into the test specimen and emulsifies the solution with the sonicator. After a specific time the emulsion is pumped through a particulate filter, the dye detector and into the waste container to provide a reference value. Once a reference value is acquired, the emulsion is diverted through a filter cartridge to remove the dyed water before it passes through the detector again and a new set of readings are taken. The water separation index is calculated from the reference value and subsequent readings. Results display on the screen.

Test results are stored on the WSI or you can save the results onto a computer.


WSI Filter cartridges use API/EI 1581 5th edition filter material which is less sensitive to weak surfactants and is less affected by SDA, eliminating uncertainty over static dissipater additives, but is responsive to the presence of ester based additives.
