Definitions

  • the invention relates to a method for determining the through the dispensing hose a fuel dispensed amount, in particular one unleaded liquid fuel for the operation of internal combustion engines, wherein the fuel is pumped from a reservoir and via a measuring unit connected downstream of the pump in the fuel flow a nozzle provided nozzle and after the start of the Tapping process by the measuring mechanism measured values for measuring the output Amount of fuel generated using a calculator to determine and display both the quantity delivered and the resulting quantity resulting price can be used.
  • the dispensing hoses of the dispensing points currently on the market will be rolled up at the tap or at least shifted when hanging back or inserted.
  • the hose is slightly tumbled and it comes to small volume changes, which are registered by the measuring mechanism.
  • the closer the pulse generator is to the next pulse edge stands there is a change in the measured and displayed Quantity and the resulting price.
  • the hydraulic area of the This phenomenon can hardly be remedied by the measuring unit, since the moving volume, that triggers this last impulse is extremely low.
  • this process is demonstrated by a change in the determined price the completion of the actual refueling process. The operators find this process particularly annoying when refueling should be terminated as precisely as possible to a predetermined amount, and this then changes slightly.
  • the invention has for its object a method of the beginning described type for measuring the through the nozzle of a tap dispensed amount of fuel to create a compensation such differences without constructive changes to the existing ones Tap construction made possible in a simple manner.
  • the solution to this problem by the invention is thereby characterized in that after an interruption of the measurement process within of a tapping process detects the first measured values generated by the measuring mechanism and compared with a predetermined, programmable number of measured values and the recorded measured values are not used when determining and displaying Quantity and price will be taken into account if the given number of Measured values are not exceeded, but the measured values recorded in the Determination and display of quantity and price are directly included, if the specified number of measured values is exceeded.
  • a review mode is started, which checks, how many measured values are recorded after the interruption.
  • the number of Measured values are recorded with a predetermined, programmable number of measured values compared. Is the specified number of measured values If the measured values are not exceeded, they are not included in the determination and display of quantity and price are taken into account. This is usually then the case when the measuring process is finally ended, typically by Attach the nozzle so that those caught after the interruption Measured values practically deleted or at least neither for the current display, still for the data transmission to a remote display and the totalizer be taken into account.
  • the measuring process is continued, i. i.e., follow the first recorded measured values further measured values, so that the predetermined If the number of measured values is exceeded, then these first measured values counted immediately and for the determination of quantity and price considered.
  • the compensation method with which one so-called overrun suppression is realized, even on a larger one Number of specified measured values can be used.
  • Compensation method for overrun suppression in the above described manner only if the measuring process for a Minimum period of time is interrupted. So it becomes a programmable one Time period specified, for example 1.5 to 2 seconds, and after the Interrupting the measuring process, the time is measured. Only when the predetermined period of time is exceeded, the procedure for detection and initiated for the comparison of measured values.
  • the program is reset, so that at each The method according to the invention was restarted at the start of a tap operation becomes.
  • the method according to the invention does not require any design or equipment Modification of existing taps, but can be done through programming of the existing electronics. It is therefore without greater difficulties can be retrofitted to existing tapping points.
  • the tap shown schematically in FIG. 1 shows a tap 1, in to which a pipeline 2 is laid, at the upper end of which a nozzle 3 connected.
  • This dispensing hose 3 is over two deflection rollers 4 performed, pulling out the tap hose 3 from the pump mast 1 enable.
  • a nozzle 5 is arranged, which is used when not in use in a holder 6 of the mast 1.
  • the fuel to be dispensed through the nozzle 5, preferably a unleaded liquid fuel for internal combustion engines is not one reservoir shown through a filter 7 from a pump 8 sucked, which is driven by an electric motor, not shown.
  • This electric motor and thus the pump 8 are switched on as soon as that Nozzle 5 is removed from its holder 6.
  • the bracket 6 is provided with a switch that directly The pump motor switches on as soon as the nozzle 5 comes out of the holder 6 is removed.
  • the fuel delivered by the pump 8 is passed through a gas separator 9 and a check valve 10 fed to a measuring mechanism 11, which is preferably is designed as a piston counter, this measuring mechanism 11 is with a Pulse generator 12 equipped according to the rotational movement of the Measuring mechanism 11 and thus the fuel quantity flowing through individual pulses emits in an evaluation device, not shown in the drawing to determine both the quantity delivered and the resulting quantity resulting price can be used. Quantity and price of each fuel output will also not be on a displayed advertisement to the customer.
  • the fluid system between the check valve 10 and the nozzle 5 is usually filled with fuel. Is in the idle state consequently, fuel both in the pipeline 2 and in the nozzle 3. Since the dispensing hose 3 is rolled up over deflection rollers 4, this results in Attaching the dispensing hose to a change in volume by the meter is perceived so that the pulse generator 12 emits a pulse. The The quantity and the price are then changed and in the display shown. Even if this change is only in the pfennig range, is this is imprecise and disturbing for the operator.
  • FIG. 2 shows a pulse diagram which shows the switching on of the pump 8 at the time a in the upper part.
  • appropriate amounts of fuel are output and the pulses shown with J 1 to J 9 are determined over time.
  • the numbering is given only for explanation, a total of any number of pulses are determined, which are used to calculate the quantity and price and display them.
  • the valve is closed. No new start of the measuring process is then determined within a predetermined period of time t x . This would be the case, for example, if an operator fills an additional canister after filling a main tank or resumes fueling that has ended due to other external influences.
  • Another pulse J 10 is detected outside the time period t x . However, no further pulses follow this, but the measuring process is ended by switching off the pump in point b, for example by hanging the nozzle.
  • the tracking pulse J 10 is not used according to the invention for determining the quantity and price, but is deleted.
  • the pulse J 10 would then be taken into account in the determination of the quantity and price if further pulses were determined after its detection, for example because another reservoir is being filled Canister or the like, or a refueling process is continued.
  • the measured values must not be impulses, but can be any type of digital or analog Be measured values.
