Flagging Limits: Frequently Asked Questions

WHY DOES FLUID LIFE UPDATE THEIR FLAGGING LIMITS?

At Fluid Life, we pride ourselves in the quality of our lab services. Since we use statistically generated flagging levels, we are always able to adapt to technological, environmental, operational and other changes which impact your oil analysis results. To ensure the best product for you, our flagging limits constantly evolve just like your operation.

HOW COME MY LAST SAMPLE ISN’T FLAGGED AND IT IS NOW WITH SIMILAR TEST RESULTS?

We have updated your flagging limits to include the most recent samples as well as additional information about the unit & components. This will result in more accurate flagging limits to serve you better.

If you have more specific questions, please let us know.

WHY IS MY SAMPLE RANK SO HIGH WHEN THERE ARE NO SEVERE TEST RESULTS?

Sample Rank™ is an algorithm designed to alert you to problematic results which can cause equipment failure. Presence of fuel, water, glycol and/or a spike in particles can trigger a high Sample Rank as there is potential failure occurring. Understanding Sample Rank

HOW CAN I ENSURE MY SITE HAS THE BEST FLAGGING LIMITS?

With the recent update, we have included new information to help us compute your flagging limits. To ensure the right limits get applied to the right equipment here are some tips:

  • Ensure all unit information is correct (manufacturer, model, unit type, etc.)
  • Ensure all component information is correct (manufacturer, model, component type, component hours, reference oil. etc.)
  • Ensure a recent (less than 1 year old) reference oil sample has been provided to Fluid Life for every oil at your site.
  • Ensure representative samples are being taken and that sample information is correct (oil hours, oil change, etc.). View sampling procedures.
  • Check with your Fluid Life sales representative that your industry is correct.
  • If you are unsure where to start, contact a Fluid Life representative.

WHAT SHOULD I DO IF I HAVE UNIQUE OPERATING CONDITIONS OR DIFFERENT EQUIPMENT?

Fluid Life’s statistically derived flagging limits are best used on common equipment across common industries. If you’re site has unique operation conditions, unique equipment or has special site reliability goals then the flagging optimization product is best for you. Learn more.

WHAT SHOULD I DO IF I HAVE TOO MANY FLAGS?

Too many flags indicate that there are reliability, oil cleanliness and/or unique operating conditions at your site which are causing flagging limits to be applied that are not suitable for your company. The flagging optimization product will help your site apply statistical and engineering based logic to better your oil analysis program.

HOW DO I INTERPRET MY OIL ANALYSIS RESULTS?

Fluid Life’s reports include the results of your oil analysis including some recommendations for the problem or actions to mitigate the problems. In addition, the Sample RankTM page will help you distinguish normal results from problematic results. Read more about Sample RankTM here.

  • If that is not enough, Fluid Life offers oil analysis training courses to help our customers interpret results. View Training Services
  • If your site is interested in Fluid Life’s reliability team’s review of your samples and guidance on sample results, you are interested in Fluid Life’s CARE program.
