MODE OF FUEL RECORDING AT A FILLING STATION AND AN ARRANGEMENT FOR ITS EXECUTION Russian patent published in 2007 - IPC G01F9/00 

FIELD: the invention refers to measuring of the mass of liquids and may be used for recording fuel delivered to a filling station.

SUBSTANCE: the average density of the fuel type delivered to a user through a concrete distributing petrol pump under standard conditions. This average value of the density of fuel is taken for computed conditioned constant density of the fuel containing in a unit of volume. As fuel is consumed a new portion is poured into the reservoir measuring after that its density and the temperature. The value of the full mass consumption of fuel ordered by the user is calculated with the computed conditioned constant density. The fuel volume which must be released out of the reservoir into the distributing petrol pump on the user's order is defined with taking into consideration the factual density of the fuel in the reservoir. The indicated volume of the fuel is brought to the fuel released from the reservoir at standard conditions and is transferred in the sum of electric impulses. At that each impulse corresponds with the standard volumetric dose of current consumption of an electric volumetric measuring device of the filling station. At releasing fuel to the user the temperature of each standard volumetric dose of fuel corresponding with a single electric impulse of the volumetric measuring device is measured. After that each electric impulse of the volumetric is at first corrected, then all corrected impulses are summed up till accordance of their sum with conditioned sum of impulses representing full volumetric consumption of fuel released out of the reservoir to the distributing petrol pump on the user's order. If these sums of impulses are in accordance between themselves the delivery of fuel to the user is automatically switched off. After that information is put on display, archived and brought to date and time and if necessary the information is deducted out of the archive on a reading arrangement. For realization of this mode they propose an arrangement including a passing arrangement in the shape of the fuel distributing pump with a control arrangement and with installed on the pressure pipeline a pump, a fuel intercepting valve, a transformer of the temperature of the current fuel consumption, an impulse volumetric measuring device, a power block electrically connected with the pump, a fuel intercepting valve and a control arrangement of the filling station.

EFFECT: expands functional possibilities.
