Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic metering counter for dispensing a mixture of two liquids, in particular a mixture of fuel and lubricant.

The prior art electronic counter solutions for dispensing a mixture of two liquids use two incremental encoders as input information to provide information about the dispensed amount of the two liquids forming the mixture. The information in the form of a pulse train coming from the incremental encoders is processed by the computing unit and displayed on the displays.

The disadvantages of the present solutions are in particular the cost of incremental liquid flow sensors and the fact that the electronic counters according to the prior art cannot easily ensure the preselection of the dispensed quantity of the liquid mixture, which in the case of dispensing fuel means fuel pumps.

These disadvantages of the prior art are largely eliminated by the electronic dispensing counter for dispensing a mixture of two liquids according to the invention, which is constituted by a calculation and display unit connected by its first input to the incremental flow sensor of the first liquid and its second input to the dispensing sensor a incremental flow sensor of the first liquid is connected to a volumetric flow meter connected by its inlet to the first liquid inlet pipe and its outlet to the outlet pipe to which the outlet of the dispensing device is connected to which inlet of the second liquid is connected to the inlet. It is advantageous if a price setting circuit for the volume units of both liquids is connected to the third input of the computing and display unit.

Advantages of the electronic dispensing counter for dispensing a mixture of two liquids according to the invention, in particular in reducing the bases, resulting from the use of only one incremental liquid flow sensor. This cost reduction is particularly pronounced for an electronic meter with an indication of the ratio of liquids in the dispensed composition where two prior art incremental liquid flow sensors were used as compared to one used with a similar electronic meter of the invention. A further advantage lies in the fact that in this solution it is easy to provide the possibility of preselecting the dispensed amount of the mixture of liquids, which in the case of dispensing the fuel means the possibility of paying the required amount of the mixture in advance and thereby speeding up operation of the fuel pumps.

The invention will now be described in more detail with reference to the accompanying drawing, in which an exemplary embodiment of an electronic meter for dispensing a mixture of two liquids according to the invention is shown schematically.

The electronic dispense counter for dispensing a mixture of two liquids according to the invention consists of a calculation and display unit connected by its input with an incremental sensor 2 of the first liquid flow and its second input with a sensor (3 set dispensing liquid ratio connected to the liquid adjusting device). In this case, the incremental flow sensor 2 of the first liquid is connected to a volumetric flow meter 11, connected by its inlet to the inlet line 5 of the first liquid and its outlet to the outlet line 2. To which the outlet of the dosing device 8 is connected. the second liquid inlet conduit 9. The price setting circuit 10 for the volume units of the two liquids is then connected to the third inlet of the computing and display unit 6. FIG.

In the operation of an electronic meter for dispensing a mixture of two liquids when dispensing a mixture of liquids, the inlet conduit 6 of the first liquid feeds the liquid to a volumetric flow meter 5 where the dispensed quantity is measured. display units 1. The mechanical output of the volumetric flow meter 5 through the mixture ratio adjusting device 8 by the dosing device 8 which controls the dispensing of the second liquid so as to maintain the set mixture ratio.

The outlet line 7 then dispenses a mixture of the first liquid supplied by the first liquid inlet line through the flow meter 2 and the second liquid supplied by the second liquid inlet line 2 through the metering device 2. The calculation and display unit Ί adds the volume increments of the first liquid. which receives information from the incremental sensor 2 of the first liquid flow and, based on the information obtained from the sensor 2 of the ratio of emitted liquids to them continuously calculates incremental increments of the second liquid output, the sum of the volume increments of both liquids continuously shows for dispensing a mixture of two liquids, information about the volume increments of the first and second liquids is transmitted from the computing and display unit 2 to the price setting circuit 10 for the volume units of both liquids, which multiplies them by their price, sums them up and displays the sum continuously on the display.

It is advantageous to use the fuel / lubricant mixture according to the invention.
