Set up new master meter N1 according to signal SL and SA, master meter N1 and initial baseline table N0 that this is new compare, when difference occurring, new table record is replaced initial baseline table N0 in the memory device of control electronics package VRC, thus the operation of Adjustment System transmission next time.
According to the present invention, advantageously, the setting signal S that is used for the preset proportion electromagnetic valve is had the pulse that is approximately the 300Hz fixed frequency and is consisted of by a series of, and its pulsewidth is according to adjusting based on the pre-recorded value in memory device of previous timing signal.
The 300Hz frequency is corresponding to about 3 times of the vibrating mechanism resonance frequency of proportion magnetic valve.
When every sub-distribution fuel, repeat the method.
Therefore, according to the frequency n of fuel up, control electronics package VRC:
The master meter N-1 that upgrades when considering based on previous the n-1 time fuel up, the aperture that formation setting signal S, this setting signal S can the preset proportion electromagnetic valves is sent to proportion magnetic valve so that the A/L ratio remains on predetermined value with this setting signal S; And
Simultaneously, set up new master meter N according to the signal SL and the SA that are sent to by liquid measure instrument and flow counter on the control electronics package VRC;
Then, after fluid transport finished, master meter N and initial baseline table N-1 that this is new compared, and when notable difference occurring, new master meter N is recorded in correct position place in the holder, and uses when the n+1 time fuel up.
Therefore, disclosed herein is a kind of method with the open loop approach automatic calibration equipment, the method is reliable, simple and have periodicity, and the method is not all to carry out when each fuel up, and only carries out at given pitch time when needed.
In addition, this method can be proofreaied and correct and self adaptation when any interference occurring, and described interference for example is grit to occur in the electromagnetic valve, or disturbance liquid is introduced in the vapor recovery pipeline.
Therefore, particularly, the invention has the advantages that long-time stability and the accuracy rate of the quiescent flow meter (fluidic oscillator) of use, and the temperature compensating of Comparative Examples electromagnetic valve.
According to another feature of the present invention, in initialization and initial alignment step, button box UAK is connected with control electronics package VRC, when finishing, this step pulls down this button box UAK.
In initialization and initial alignment step, technical personnel can will be used for as the button box UAK of starting switch:
Pre-determine the A/L ratio;
Set up initial baseline table N0;
Determine the height of equipment;
Pre-determine as required the stated limit of A/L ratio, surpassed this scope, alarm unit just is triggered, and these data is recorded in the memory device of control electronics package VRC.
In order to set up initial baseline table N0, particularly in order to determine that proportion magnetic valve obtains the aperture of given vapor flow rate A and must be sent to this electromagnetic valve to obtain the setting signal S of this aperture, technical personnel is connected to simulate the fuel distribution operation by the outside vapor flow rate meter with the authoritative department identification with the vapor recovery pipeline.
In initialization and initial alignment step, be necessary to pre-determine the height of the equipment that uses box UAK, can change the average atmospheric pressure reference value that flow counter adopted in measured difference and therefore to disturb in the situation of discharge measurement, measured difference is carried out adjustment for altitude.
Therefore, based on the method applied in the present invention, the difference between measured vapor flow rate A and the vapor flow rate A of processing is according to the bar pressure automatic calibration, and bar pressure can be according to the height generation marked change in installation site (sea level or mountain area).
Because the steam temperature sensor is connected with control electronics package VRC, so can also proofread and correct according to ambient temperature these differences of vapor flow rate A.
According to another feature of the present invention, by control electronics package VRC, the electric current that equally can continuous gauging flows through the proportion magnetic valve coil, and can change to adjust according to the internal resistance of being inducted by curent change of this coil the amplitude that consists of pulse of the setting signal S that sends described electromagnetic valve to.
In order to implement in a satisfactory manner method of the present invention, proportion magnetic valve must be insensitive to the caused temperature traverse of generating heat under galvanic action owing to coil.
In fact, when aliving, the coil resistance of proportion magnetic valve increases, and causes thus electric current to reduce, and causes the electromagnetic valve aperture not enough.
According to the present invention, because control electronics package VRC measures the electric current of actual passing ratio electromagnetic valve coil, and with this electric current with compare according to the electric current that is recorded in the master meter N in its memory device, therefore can stop above-mentioned electric current to reduce, thereby make proportion magnetic valve open to obtain required vapor flow rate A.
When difference occurring, in the situation that does not change table given pulse width among the N, by changing the power line voltage of pulse, control electronics package VRC can adjust the electric current of passing ratio electromagnetic valve coil, the resistance variations that occurs under temperature effect with compensating coil.
Therefore, control electronics package VRC at first carries out width adjustment to the fixed frequency pulse that consists of setting signal S, to increase or to reduce the aperture of proportion magnetic valve, and control thus vapor flow rate SA, secondly, according to the temperature traverse of proportion magnetic valve coil vertical amplitude adjustment (voltage) is carried out in these pulses.
