Systems operable to blend at least one finished gasoline from a refined petroleum product comprising at least one neat gasoline with ethanol and optionally butane utilizing a blend model that calculates a volumetric blend ratio comprising at least one neat gasoline, ethanol and optionally, butane. The blend model incorporates estimated values for the octane number and the volatility of the ethanol and butane when calculating the volumetric blend ratio.

A liquid preparation method is provided. The method includes measuring, with a detection member, a quantity of a liquid stored in a liquid tank by emitting a detection signal toward a floating member positioned in a tube. The tube extends in a height direction of the liquid tank and fluidly connects to two connecting ports of the liquid tank that are located at opposite sides of a surface of the liquid, and the position of the floating member in the tube varies according to a level of the liquid in the liquid tank. The method also includes regulating the liquid in the liquid tank in response to the quantity of the liquid in the liquid tank.

The disclosure relates to systems for distributing alcohol-containing gasoline. The systems herein facilitate the combination of gasoline blendstocks and alcohols to create finished gasoline products. The systems herein also measure the volumes and other characteristics of the gasoline blendstocks and alcohols and feature computers and controllers that can calculate the gross and net volumes of liquids, including the net volume of finished gasoline products.

Introduced here are systems for customized formulation and production of cleaning products and associated methods for using those systems. A system may include a computer-implemented platform (also referred to as a formulation platform or production platform) that is communicatively connected to an interactive dispensing machine responsible for making cleaning products. An individual or company may be permitted to select, create, or modify formulas via the production platform, while the interactive dispensing machine can produce cleaning products in accordance with those formulas.

A method of delivering a selected fuel product having a selected octane level to an operator from a fuel dispenser including a blend manifold, a fuel nozzle, and a fuel hose extending therebetween, including the steps of determining a first volume of a first fuel that is retained in the fuel hose upon completion of a first fueling event, determining a first octane level of the first volume of the first fuel, determining a second volume of a second fuel having a second octane level, and delivering the first fuel volume and the second fuel volume to the operator during a second fueling event, wherein a total volume of fuel equaling the first volume of the first fuel and the second volume of the second fuel has a total octane level that falls within a predetermined limit of the selected octane level of the selected fuel product.

Blending of available fluids for a vehicle is provided. It is received, to the vehicle from a fluid dispenser over a bidirectional filling communications session, information indicative of a plurality of available fluids for dispensing from the fluid dispenser into a fluid reservoir of the vehicle. It is indicated, from the vehicle over the bidirectional filling communications session to the fluid dispenser, a first quantity of a first fluid and a second quantity of a second fluid to be dispensed to the vehicle as a blend. It is received the first quantity of the first fluid and the second quantity of the second fluid into the fluid reservoir of the vehicle.
