Know how much fuel is actually in each tank, how much the meters sold, and where the difference came from — every single day, not at month end.
At many outlets the dip reading lives in one register, meter readings in another and the delivery challan in a file. If these records are compared only after several days, it becomes difficult to identify which shift, tank, delivery or reading created the difference.
A difference does not automatically prove loss. Incorrect dip technique, an unsuitable calibration chart, meter-entry errors, delivery timing, nozzle mapping, temperature and authorised stock movements can all affect the comparison. The first task is to make sure the readings describe the same tank and time period.
Use the same sequence every day: map every active nozzle to its source tank, verify the previous closing, take the dip consistently, record receipts against the correct tank, close the meters for the mapped nozzles, and then compare expected closing with actual closing. Review an unusual number before accepting the day.
Before closing the record, confirm that the dip belongs to the correct tank, all relevant deliveries are entered, nozzle mappings are current, meter digits and decimal places are correct, and any stock adjustment has a written reason. If a tank has no comparable nozzle readings, treat the entry as a check item rather than calling the entire stock movement a loss.
Do not combine tanks of the same fuel into one unexplained total, reuse a calibration chart from another tank, record a delivery against the wrong tank, or treat every positive variance as leakage. Avoid correcting a result merely to make it zero. Correct the source entry when it is wrong; otherwise preserve the observed figure and investigate the pattern.
This example is not customer data. A diesel tank opens at 9,200 L, receives 12,000 L and its mapped nozzles record 10,400 L sold. Expected closing stock is 10,800 L. If the calibrated closing dip is 10,785 L, the difference is 15 L. The manager should first recheck the source readings and timing, then compare the result with prior shifts before deciding what it means.
Software reduces repeated arithmetic and keeps the dip, delivery, nozzle and adjustment records together. PetroPulse360 provides a digital DIP register, tank calibration conversion, nozzle-to-tank mapping, per-tank comparison, recorded adjustments and stock reports. It helps surface unexplained variance; it does not prove theft or replace physical inspection and calibration.

Record the opening dip, all deliveries and the closing dip for each tank, total the meter sales for the nozzles on that tank, and compare expected closing stock with the actual dip. Doing it daily per tank is what makes the number useful.
Yes, for accurate litre conversion. You enter your tank's calibration chart once, and dip readings in millimetres are converted to litres automatically after that.
No. Temperature, calibration tolerance and evaporation all affect the figure. Persistent or growing variance on one tank is the signal worth investigating, which is why PetroPulse360 tracks the trend and not just a single day.
Owners and managers can make a stock adjustment, but a reason is mandatory and the adjustment is recorded in the activity log.
Stock variance was the problem that started this software. A dip book, a meter register and a delivery challan in three different places means nobody can tell you on a Tuesday whether the tank is short.
