Fuel Oil Sample Collection
The tube within the sampler and sample valve should always be cleaned before use. This can be achieved by removing the tube, simply flushing it with a clean distillate fuel and allowing it to drain thoroughly before installing. The use of low flash point solvents is not recommended for cleaning the sampler. The tube should always be installed with the holes facing the direction as shown.
When bunkering starts, place a container under the sampler, open the sampler valve fully and flush the sampler with fuel. Close the valve and attach a cubitainer onto the valve as shown. If the sample is required only for testing on site, then it is possible to substitute a single sample bottle in place of the cubitainer.
Adjust the needle valve to give a slow and steady drip. Time the fill rate to estimate that it will provide for sufficient sample over the expected delivery period. If the cubitainer fills during the bunkering period, remove it and add a numbered, tamper evident cap. Place an empty cubitainer on the sampler and continue to draw a sample. On completion of the bunkering, remove and seal the cubitainer, fully open the sampler valve and allow the sampler to drain.
