摘要： A method for calibrating a filling system is disclosed. In a first calibration step, a calibration of a calibration variable of a first flow or level measuring device is performed at a first calibration point. In a first deviation determination step, the first control and evaluation unit of the measuring device determines an average deviation of the calibration variable from a desired value. In a first correction step, the first control and evaluation unit corrects a calibration parameter taking into account the determined deviation. In a first transmission step, the first control and evaluation unit transmits the determined deviation and/or the corrected calibration parameter to the second control and evaluation unit. In a first adaptation step, the second control and evaluation unit corrects a calibration parameter at a first calibration point, taking into account the deviation transmitted by the first control and evaluation unit or the transmitted calibration parameter.

摘要： In one aspect, fuel inventory data characterizing a level of fuel stored at a fuel storage facility can be received from a sensor in operable communication with the fuel storage facility. Flow meter data characterizing an amount of fuel dispensed from the fuel storage facility by a fuel dispenser nozzle can be received from a flow meter in fluid communication with the fuel dispenser nozzle and the fuel storage facility. Fuel transaction data characterizing the dispensing of fuel by the fuel dispenser nozzle and the dispensing of the fuel by one or more additional fuel dispenser nozzles in fluid communication with the fuel storage facility can be received. An estimate of meter drift characterizing a change in calibration of the flow meter can be determined based on the fuel inventory data, the flow meter data, and the fuel transaction data. The estimate of meter drift can be provided.

摘要： A mechanical system for calibration during a chemical feed process includes a ball valve that includes three openings. The ball valve is in communication with a lever, which when turned to a fill position, allows the filling of a drawdown cylinder for calibration. The ball valve automatically returns to its original default position within about a minute with a spring force automatically pushing it back to its start position.

摘要： An automated liquid inventory monitoring and inventory reconciliation system. The system uses a liquid densitometer to precisely measure the density of liquid being dispensed. This allows the system to account for the significant temperature-induced volume variations existing in common liquids such as gasoline. In the preferred embodiments, a fuel inventory processor tracks the quantity of fuel loaded into the tank and the quantity of fuel dispensed to maintain an ongoing computation of the quantity of fuel that should be present in the tank. An accurate tank depth measurement device is also employed. The processor compares the tank depth measurement to the computed quantity of fuel in the tank and uses the values to create an updated tank strapping chart.

摘要： A method and apparatus for improving the accuracy of fuel flow meters by compensating for the presence of vapor bubbles generated within the flow meter. The method comprises measuring the temperature of the fuel flowing through the meter and using an algorithm or static lookup table to determine a vapor compensation factor based on that temperature. Because the tendency of fuel to vaporize depends largely on seasonal variations in fuel temperature, applying a temperature-dependent vapor compensation factor promotes year-round accuracy of the flow meter output.

摘要： A portable fluid monitoring controller tester system for fluid monitoring equipment includes a control panel, electrical interfaces, and associated circuitry for simulating the fluid overfill sensors and other features of a trailer. The tester is a self-contained device that meets or exceeds various safety standards applicable to operating in an explosive environment. The tester may be powered, at least partially, by the fluid monitoring controller to which it is connected or from another power source, such as a battery. The tester has intrinsically safe outputs, and is configured to simulate different types of sensor systems found in fuel tanker trailers, including 2-Wire Optical, 5-Wire Optical, and Thermistor sensors. The tester is further configured to simulate ground circuits and the truck identification module (T.I.M.) of the fuel tanker trailer. The tester includes an enclosure that is impact and temperature resilient, and provides protection against windblown dust, rain and splashing water.

摘要： Automatic calibration of dispense parameters of a product dispense system is accomplished via electronic communication of product information. A chemical product includes an electronically readable tag or label that stores and communicates chemical product data concerning the chemical product to a chemical product dispenser. The chemical product data may include, for example, the name of the chemical product, the type or class of the chemical product, manufacturing information regarding the chemical product (e.g., manufacturing date, location, serial number, lot number, etc.), concentration of active ingredient(s), weight, volume, viscosity, density, hardness, specific gravity, shape, color, and/or other data concerning the chemical product. A controller within the dispenser automatically calibrates the dispense parameters based on the chemical product data.
