A fuel storage system has a tank access chamber with improved monitoring, servicing and maintenance capabilities. In particular, the chamber includes a sump monitored by a liquid sensor whose proper function can be automatically checked remotely, e.g., via an electronic controller or remote manual operation. In cases where such a check indicates a need for physical inspection of the sump sensor, the present system provides for sensor removal and installation by service personnel from a location outside the tank access chamber. Thus, the present system facilitates regular inspection and routine or unplanned maintenance without the need for a person to physically enter the tank access chamber.

Disclosed herein is a telemetric fitting for a liquid-level gauge, the telemetric fitting configured to derive liquid-level information from the liquid-level gauge when attached thereto, and to wirelessly transmit at radio frequencies the liquid-level information.

A system and method for monitoring and treating petroleum in a storage tank is provided. The system and method comprise including a plurality of vertically spaced sensors inside the tank, the plurality of vertically spaced sensors being in communication with a computer. The computer is able to calculate the quantity and quality of the petroleum in the tank based off the readings from the plurality of vertically spaced sensors. As a result, the petroleum in the tank can be optionally treated prior to sale in order to optimize the price received for the petroleum in the tank.

A sensor assembly is described herein that can automatically calibrate itself upon installation into an empty bin, eliminating the need to actually fill the bin to calibrate the level reading. The sensor will provide consistent measurement regardless of material properties (permittivity, density, temperature or moisture content). The capacitive nature of the sensor means that in some circumstances, it will sense the material through plastic/glass/fiber glass thereby allowing the sensor assembly to be mountable on the outside of a bin or container. The electrodes of the sensor system are designed to provide a continuous level reading.

According to one implementation, a flight support system of an aircraft includes storage and an information processing device. The storage stores position information on at least one river above which a space is an option for a flight path of the at least one aircraft. The information processing device automatically determines at least whether the flight path of the at least one aircraft should be over a specific river included in the at least one river in order to fly the at least one aircraft to a destination, based on the position information stored in the storage.

A measuring device, measuring arrangement and a method for determining a measured quantity. The measuring device a sensor device, an evaluation device and an interface. The sensor device generates measurement information which is dependent on the measured quantity and the evaluation device determines a result value for the measured quantity. To devise a measuring device which manages with a limited power demand and storage demand and which also allows a complex evaluation for obtaining the result value for the measured quantity, the evaluation device of the measuring device outputs the measurement information or information dependent on it via the interface to a separate data device of the measuring arrangement, receives intermediate information from the data device which is generated depending on the measurement information or the information dependent on it and determines the result value based on the intermediate information.
