Heating oil receipt directions
The volume of your tank is measured as follows:
We measure the three dimensions (height, width and length) of the tank in centimeters.
The capacity (volume) of your tank (in liters) is:
Volume = length (in cm.) x width (in cm.) x height (in cm.) divided by 1.000
For example if you measure
Height = 100 cm
Width = 100 cm
Length = 200 cm
then the capacity (volume) of the tank is:
volume = (100x100x200): 1.000 = 2.000 liters
Measurement of quantity delivered
To measure the amount of oil delivered, use a measurement stick or a meter (either yours or the driver’s). In all cases, you must make sure that the meter has the right grading and that it is fully developed during measurement. Respectively, the stick must be straight, without distortions.
To measure the delivery quantity, you must multiply:
Length (in cm.) x width (in cm.), where the height difference will be the amount of oil after delivery (measurement) minus the oil level you had measured before the delivery (estimate of quantities).
Therefore, if for example before delivery you measured that the oil level was at 15 cm. and after delivery it went to 65 cm., then the amount delivered to you in liters is:(65–15)x100x200:1.000) – 1.000 liters
- During estimate of quantities and measurement, the meter or the stick should touch the bottom of the tank and be therein placed vertically.
- The meter must be rigid and the stick must be straight without distortions.
- Place the meter or the stick at the same place during estimate of quantities and measurement.
- To make the measurement, please wait 2-3 minutes after delivery, so that the oil surface “calms” from foaming and you can precisely see the height of the oil.
- Ensure that the content of the hose completely empties your tank. This is normally performed by providing air pressure at the end of the delivery.
- At the end of the delivery, when the hose is empty, make sure the meter stops counting.
- Be present during delivery and especially during estimate of quantities and measurement. The results of the estimate of quantities and measurement must (in accordance with market regulations) appear on the consignment note, after having been previously agreed between you and the carrier.
Measurement through tank meter
You can use the tank meter as complementary measurement. However, in any case, the estimate of quantities – measurement method is deemed to be the safest one, as long as it is performed correctly. If you use a tank meter, make sure the content of the level pipe is similar to the tank’s content and not some lighter fluid which will show a higher level than the actual one.
Measurement through fuel tender meter
if you have a metal tank, consult the tanker meter as an auxiliary measurement method.
Maintenance & cleaning
Ensure frequent cleaning of the burner, as well as of the oil tank.
The plastic tanks, due to their shape (they are usually bending or not rectangular), as well as due to the non-stability in their shape, depending on the fuel contained, are not deemed to be reliable for measurement with the classic meter or the stick. In this case, make sure the manufacturer has given the grading of the volume on a side marker (having of course taken into account the deformation).
In order the estimates of quantities and the measurements to be correct, their manufacture should not alter their geometry when adding the oil. This can only be ensured by the manufacturer.
