Abstract:
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.
Abstract:
An automated wetstock management system can include a plurality of sensors disposed in a fuel storage facility, the plurality of sensors configured to sense fuel data characterizing one or more aspects of the fuel storage facility, and a wetstock management server communicatively coupled to the plurality of sensors. The wetstock management server can process the fuel data to detect whether the fuel data satisfies an exception indicative of an operational issue of the fuel storage facility based on one or more predefined rules or models stored in the wetstock management server. In some embodiments, the wetstock management server can generate a workflow for assisting a user of the fuel storage facility to resolve the operational issue. In some embodiments, the wetstock management server can assign a risk category to the exception and electronically transmit an alert characterizing the operational issue to the user.
Abstract:
The fluid in a vessel can be monitored in real-time by a system that consists of at least a level module positioned proximal a vessel. The level module may be connected to a first sensor and a second sensor that are each attached to the vessel and responsive to changes in fluid within the vessel. The level module can employ a stored log of sensor measurements to provide a real-time volume of fluid within the vessel while fluid is flowing into or out of the vessel.
Abstract:
A method of reporting fuel consumption, the method comprising: providing a vehicle having a fuel level monitor; repeatedly measuring fuel consumption by the vehicle with the monitor; providing a server operable to generate fuel consumption reports, and transmitting the fuel consumption measurements via a communication channel between the fuel level monitor and the server.
Abstract:
A method and device for visually recording hydraulic conductance through a sectioned piece of dentin; and which can be used to measure the effectiveness of treatments to reduce the permeability of dentin.
Abstract:
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.
Abstract:
An apparatus for metering the delivery of a fluid. The apparatus has a variable acoustic source and a microphone, both acoustically coupled to a volume having a fluid region and an air region. The apparatus may also include a processor to determine a volume of the air region based on signals received from the microphone and the variable acoustic source. A fluid valve is coupled to the processor, and is configured to allow an amount of fluid to exit the fluid region associated with the volume of the air region.
Abstract:
A fluid flow testing apparatus for measuring the pour profile of a container has a rotatable container carrier and an assembly for rotating the container between a first position allowing fluid to be retained within the container and a second position causing fluid to be poured from the container. Sensors for sensing the weight of the container as liquid is poured from the container are provided in order to determine the pour profile of the container. A controller receives input signals from the sensors in order to record the weight of the container over time as liquid is poured from the container as the container is rotated. The change of weight of the container over time establishes a pour profile for the container.
