SelfTank ASTM
Description of a product
SelfTank ASTM
All liquids change capacity, when are changing temperature. In practice all the time are changing fuel capacity in storage tank.
Device SelfTank ASTM permanently registers changed temperatures of fuel in tank. On this ground SelfTank ASTM calculate fuel density and capacity in +15ºC.
This solution does possibility of fuel settling in the same temperature.
The event effect of capacity changing, shows example:
A customer received 20 000 ltr of fuel in +15ºC and in density 837 kg/m. After night outside temperature falled to +5ºC. Morning customer had in tank only 19 836 ltr*.
When in winter time temperature fall to -5ºC, in tank will be only 19 667 ltr.
Morning driver filled two tanks 450 ltr of each, together 900 l. Temperature of fuel was -5ºC. He filled not 900 ltr, he filled 914 ltr.This event is much more bigger in above ground tanks.
When we receive fuel in temperature +15ºC, we should report fuel in the same temperature.
*calculation base on ASTM-ISOD1250-80 Petroleum MeasurementTables
