5 tips to get accurate SIR data


You’ve just received your monthly SIR Report and your tank has not passed. The SIR data results say the tank is losing fuel.

If you’ve been using a dipstick to measure your wet stock, the best case scenario is that the data is incorrect because reconciliation procedures haven’t been followed.

The worst case scenario is that the data is correct, and your tank is leaking fuel.

But how can you decide on the next course of action if you don’t have confidence in the accuracy of your data?

What are the risks of inaccurate SIR data?

Tank reconciliation data shouldn’t be taken lightly – and for good reason. Inaccurate data can make a tank appear to be gaining or losing fuel and can mask potential issues with your tank, including potential leaks.

If your dipstick data is incorrect, the SIR Report may not even be able detect a leak.

Fuel leaks that go undetected cause extensive contamination to the surrounding environment and lose you thousands of dollars in revenue. If your leak gets reported to the EPA, your site is at risk of being shut down and, depending on the damage your leaking tank has caused, you could be facing fines in excess of $100,000.00.

Of course, your tank may not be leaking, and your SIR data may just be inaccurate. But why take the risk? There are measures you can take to ensure your SIR data is accurate.

Here are 5 tips to get accurate SIR data:

At EMS, we recommend actioning these five tips to get your data accurate every time you measure your tank.

  1. Timing is everything. Record the sales and dip readings at the same time every day. Ideally no fuel should be sold between recording sales and dipping the tank.
  2. Be consistent. Our recommendation is to dip the tank 3 times and take the average, rounding to the nearest increment of the dipstick. Diesel can be tricky, so dip slower to get a more accurate reading.
  3. Cover the ins and outs. Have you included all your deliveries, meter tests or tank swaps? Are you recording the right delivery volume? Check that your sales data is collating properly.
  4. Revise your data. If you see something odd, dip again.
  5. Ask the experts. EMS is always available for advice via phone, email and the data entry portal.
