It compares, can reduce by a flowmeter, so as to reduce the setting and management cost of flowmeter.
In addition, standing tank 31 and the spare oil tank 33 of HFO in the 3rd embodiment for HFO, using liquidometer 144 and liquid
Position counts 145 to measure the storage capacity (volume) of the HFO in tank, and then uses flowmeter 143 to measure for HFO oil storage tank 12A
The amount for the HFO being discharged from tank.Liquidometer can be used also to measure from tank for HFO oil storage tank 12A as instead of structure
The amount of the HFO of discharge.But as described above, it may be gone out in the biggish situation of capacity of tank using liquidometer measurement volume
Existing error.Therefore, by being selected to obtain flowmeter using liquidometer according to capacity of tank etc., it can more accurately measure and disappear
Consumption.In the structure shown in the 3rd embodiment, tank 31 and the spare oil tank 33 of HFO are stood compared to HFO in HFO oil storage tank 12A
Capacity it is smaller situation it is more, therefore as set forth above, it is possible to think, stand tank 31 and the spare oil tank 33 of HFO for HFO, i.e.,
The amount of the HFO in tank is measured using liquidometer, is also able to maintain measurement accuracy sufficiently high.
In addition, the storage in the 3rd embodiment, to the fuel oil in the 2nd fuel oil side (that is, the side HFO) measurement pans
The case where amount, is illustrated, but naturally it is also possible to also use same structure in the 1st fuel oil side (that is, the side DO).Also,
It can also be using the structure for the storage capacity for measuring the fuel oil in pans two fuel oil sides.But shown in Fig. 2 and Fig. 3
Example in, be provided in DO oil storage tank 11A by the foldback path L13 of the DO foldback of overflow.The case where using this structure
Under, if flowmeter only is arranged on the path L11 from DO oil storage tank 11A as flowmeter 143, can not accurately measure
The DO being discharged out from DO oil storage tank 11A.Therefore, it is necessary to suitably change the configuration of flowmeter etc..It in this regard, will be next
It is illustrated in variation.
(variation)
Fig. 4 is to indicate that the variation as fuel management systems 4 involved in the 3rd embodiment changes fuel management systems
The figure of the example of path a part of the side HFO in 4.Road in Fig. 4, with the HFO in fuel management systems 3 shown in Fig. 3
Diameter is compared, and has added a pans, and added path between the tank and other tanks etc..Also, correspond to the path
Change, the structure of the fuel consumption determination part of the side HFO becomes different.
In variation shown in Fig. 4, identically as fuel management systems 4, in section more posteriorly than HFO oil storage tank 12A, shape
At there is the circulating path (clarifier 32 is omitted in Fig. 4) for standing tank 31, clarifier 32 and the spare oil tank 33 of HFO including HFO.And
And a part of HF O branched out from the spare oil tank 33 of HFO is supplied by path L25 to for generator 15A and ship master
The interflow path L31 of machine 15B supply fuel oil.Also, it stands a part of HFO that tank 31 branches out from HFO to supply by path L26
To for the interflow path L32 to boiler 15C supply fuel oil.
On the other hand, it in variation shown in Fig. 4, is provided with and stands in the case that overflow occurs in tank 31 in HFO from HFO
It stands tank 31 and the spare oil tank 33 of HFO imports the assistant tank 34 of a part of HFO.Tank 31 and the spare oil tank 33 of HFO and pair are stood in HFO
Path L27 is provided between tank 34.Also, the HFO of assistant tank 34 is returned to HFO oil storage tank 12A or path by path L28
Specific discharge meter 143 on L21 is located further forward the position of section (example being returned on the L21 of path is shown in Fig. 4).
In the case of this kind of construction, compared with structure shown in Fig. 3, assistant tank 34 is increased as pans.Cause
This, is passed through setting liquidometer 146 and is measured the amount (volume) for being stored in the HFO of assistant tank 34 using the height of liquid level, can
The HFO being stored in assistant tank 34 is taken into account and is calculated the consumption of HFO.
On the other hand, flowmeter 143 can measure the amount from the HFO oil storage tank 12A HFO being discharged, still, the measurement result
In include the amount for the HFO that foldback comes by assistant tank 34.Therefore, if measurement result based on flowmeter 143 and by liquidometer
144, the HFO storage capacity in the pans of 145,146 measurements and calculate the consumption of HFO, then will appear with by assistant tank 34
And the corresponding error of amount for the HFO that foldback comes.
Therefore, in the structure of the variation shown in Fig. 4, setting is returned to for measuring from assistant tank 34 on the L28 of path
The flowmeter 147 of the amount of the HFO of the leading portion of flowmeter 143.Moreover, by subtracting base from the measurement result based on flowmeter 143
In the measurement result of flowmeter 147, it can find out the HFO's that back segment is discharged in the HFO for being originally stored in HFO oil storage tank 12A
