A portable fuel metering system (PMU) is described. The PMU has one or more flow meters capable of metering the flow of fluids, such as fuel, as the fluid is transferred from a source to a receiver. The PMU may include a telemetry unit configured to transmit parameters related to the fuel transfer to remote location. The PMU may be configured in a light, portable package that may be carried by one or two people. The PMU may include a power generator that is configured to use the flow of fluid to the PMU to generate power for the PMU's operation.

A fuel management method for long term stationary truck use is provided. This method includes a truck with at least a first saddle tank or a second saddle tank integral to the truck. Each saddle tank has a fuel level sensor to measure the fuel level. A fuel trailer provides supplemental fuel, and a fuel pump downstream of the fuel trailer and upstream of the truck pressurizes the fuel from the fuel trailer. The method includes supplying fuel to local users from saddle tanks, activating the fuel pump when the fuel level of both the saddle tanks is less than a first predetermined threshold, thereby transferring fuel from the fuel trailer to the first saddle tank and the second saddle tank, deactivating the fuel pump when the fuel level of either the saddle tanks is greater than a second predetermined threshold.

Apparatus (2) for monitoring a set of fuel dispensers (10.sub.1, 10.sub.2, . . . 10.sub.N) of filing stations (1.sub.1, 1.sub.2, . . . 1.sub.M), for providing fuel stored in tanks (11) to vehicles, may include interfaces (21) to receive measurements from output probes (30.sub.1, 30.sub.2, . . . 30.sub.N) measuring fuel flowing through nozzles (11.sub.1, 11.sub.2, . . . 10.sub.N); measurements from amount probes (31) measuring a stored amount contained within the tank; and receipt data of fuel delivered; a memory (22) to store at least part of said measurements, and a computing means (23). The computing means may be configured for: determining two subsequent fuel deliveries for which stored amounts measured at the start of said deliveries are substantially equals; determining a suspicious situation by comparing said receipt data corresponding to said subsequent fuel deliveries with the sum of measurements provided by said output probes during the time period between these two subsequent deliveries; and triggering an action when a suspicious situation is determined.

A system for controlling selection and distribution of a product in a product dispensing system. The system includes a user interface for prompting a selection and selecting the product, a machine control processor in communication with the user interface, a power distribution module connected to the machine control processor, and a power supply unit for supplying power to the system through the power distribution module.

A fuel storage and supply arrangement serves as a source of fuel to be dispensed via at least one fuel dispenser in a fuel dispensing environment. The arrangement comprises a storage tank for containing a quantity of the fuel. A pump assembly draws the fuel from the storage tank providing the fuel under pressure to a fuel supply line. A fuel conditioning assembly includes a housing having a storage volume, a housing inlet receiving the fuel under pressure created by the pump assembly, a housing outlet through which fuel exits the housing, and a housing port through which fuel can be drawn into the housing. A vacuum source in fluid communication with the housing outlet is operative to selectively apply a vacuum to the outlet of the housing so that liquid can be drawn into the housing via the port. A water intake device is in fluid communication with the housing port. The water intake device has at least one inlet situated adjacent to a bottom of the fuel storage tank.

A system for monitoring flow conditions of fluid flowing from a product container through a solenoid pump. The system includes at least one solenoid pump comprising a solenoid coil, which, when energized, produces a stroke of the solenoid pump, at least one product container connected to the at least one solenoid pump wherein the at least one solenoid pump pumps fluid from the at least one product container during each stroke, at least one PWM controller configured to energize the at least one solenoid pump, at least one current sensor for sensing the current flow through the solenoid coil and producing an output of the sensed current flow, and a control logic subsystem for controlling the flow of fluids through the solenoid pump by commanding the PWM controller and for monitoring the current through the solenoid pump by receiving the output from the current sensor, wherein the control logic subsystem uses the measured current flow through the solenoid coil to determine whether the stroke of the solenoid pump is functional.

A system determines an interaction period during which a fuel dispensing operation is performed at a fuel dispensing terminal. The system determines a measured volume per unit time parameter associated with fuel dispensed from the fuel dispensing terminal by dividing the determined volume for fuel by the interaction period. The system compares the measured volume per unit time parameter with a threshold volume per unit time parameter. In response to determining that the measured volume per unit time parameter is less than the threshold volume per unit time parameter, the system retrieves a video feed that shows the fuel dispensing terminal during the fuel dispensing operation. The system creates a file for the fuel dispensing operation. The system stores the video feed in the created file.

The invention relates to a withdrawal system (1) for filling and emptying containers and involves a container closure (2) that is inserted into a container opening of a container seating a bung head. An immersion pipe (4) connected to the bung head has an extraction connector element connected to the immersion pipe (4) or the bung head. A transponder generating a transponder signal is provided; a monitoring signal is generated in dependence upon the transponder signal that indicates whether there is a permissible connection of the extraction connector element to the container.

The system includes a user interface for prompting a selection and selecting the product, a machine control processor in communication with the user interface, a power distribution module connected to the machine control processor, and a power supply unit for supplying power to the system through the power distribution module.

A tank volume measurement system and method. The tank volume measurement system receives a tank identifier indicating which tank the level sensor is sensing, receives a tank level indication from a level sensor, correlates the tank level to a tank volume using a calibrated strapping chart, and outputs a volume indication to a user.
