" calculating effectively definitely liquid resistance according to the resistance of relative liquid " above-mentioned is, it is necessary to which explanation, processor 14 can be from
With respect to the numerical value that effectively absolute liquid resistance is calculated in the numerical value of liquid resistance.Because measure liquid resistance in such as the 3rd liquid resistance sensor 7
During numerical value, a certain amount of oil gas between the 3rd petroleum vapor recovery pipeline 6 and oil tank 11 be present, it is so inevitable in the 3rd petroleum vapor recovery
A certain amount of air pressure between pipeline 6 and oil tank 11 be present, so the liquid resistance numerical value that now the 3rd liquid resistance sensor 7 measures is actually
Include unborn oil gas air pressure between the 3rd petroleum vapor recovery pipeline 6 and oil tank 11, be not reflected in the 3rd liquid truly
The liquid resistance of the opening position of sensor 7 is hindered, is hindered so the liquid resistance at this moment measured is properly termed as relative liquid.In order to preferably reflect the 3rd liquid
Hinder the true liquid resistance of the opening position of sensor 7, i.e. effectively definitely liquid resistance, needed when calculating the 3rd liquid resistance sensor 7 is real
The relative liquid resistance of border measurement subtracts now unborn oil gas air pressure between the 3rd petroleum vapor recovery pipeline 6 and oil tank 11, ability
Obtain effective definitely liquid resistance numerical value of the liquid resistance situation of true reflection the 3rd liquid resistance opening position of sensor 7.As for particular point in time
The 3rd petroleum vapor recovery pipeline 6 and oil tank 11 between unborn oil gas air pressure how to measure, can by means of with oil tank 11
The sensor 15 of coupling, such as baroceptor or differential pressure pick-up commonly used in the art, for continuously detecting in oil tank 11
The oil-air pressure in portion and obtain.Memory 13 can also store the oil-air pressure detected by sensor 15 and corresponding time.
These oil-air pressures and corresponding time can be stored in the form of computer code on memory 13.Although in Fig. 1
In be not shown connecting line between sensor 15 and memory 13, but that is just for the sake of the succinct needs of accompanying drawing, actually

Art personnel should be understood that existing many sensors equally have the function of data storage, be needed in mass data
In the case of storage, these data, which will be transferred, to be stored in memory 13.
On " calculating effectively definitely liquid resistance according to the resistance of relative liquid ", alternative, in one embodiment of the invention, such as
Such as HZD YZ- only can be installed on the 3rd petroleum vapor recovery pipeline 6 apart from the 3rd fuel charger 3 of the distalmost end of oil tank 11

Converting unit is equivalent to the memory 13 and processor 14 contained shown in Fig. 1), environmental monitoring data converting unit is to these
Screened with respect to liquid resistance numerical value, reject irrational numerical value, for example, the obtained negative of those detections with respect to liquid resistance numerical value, it is necessary to
Rejected；In addition for extra high relative liquid resistance numerical value, for example other numerical value are arrived 500 in effective period of time
Between 1000Pa, there is a relative liquid resistance numerical value 2000Pa even more high, this obvious high numerical value also irrational numerical value,
Also it will be weeded out, and finally filter out rational relative liquid and hinder.Because during actual 3rd fuel charger 3 refuels, the
Pressure in three petroleum vapor recovery pipelines 6 is continually changing, and rational relative liquid resistance here is obtained after extremum is deleted
Correction after relative liquid hinder.Effectively definitely liquid resistance is by will hinder the 3rd petroleum vapor recovery pipeline subtracted now with respect to liquid after correction
