The oil field lease management and security system and method of the present invention for monitoring oil field equipment and for communicating with authorized operators. The system of the present invention includes a plurality of transducers connected to the equipment for sensing operational parameters of the equipment such as fluid levels in oil field storage tanks, a plurality of controllers connected to the equipment for controlling operational components of the equipment such as determining when an oil tank is filled and activating a shut-off valve to prevent further filling of the tank, a communication access panel for allowing an authorized operator to interface with the system, and a monitoring system interconnected with the transducers, the controllers, and the communication access panel for periodically monitoring each of the transducers and the communication access panel wherein the monitoring system is capable of storing transducer information corresponding to the operational parameters from the transducers such as the levels of oil in the storage tanks and operator information from the communication access panel such as the operator's password and access code.

Oil field lease management and security system and method therefor

A storage tank level monitoring apparatus and method for determining fluid levels in a storage tank. The apparatus of the present invention includes a magnet coated with rubber for holding a pivotally mounted housing to the interior of the storage tank and an ultrasonic transducer contained within the housing for generating acoustic pulses and for receiving reflections of the acoustic pulses for producing an analog signal proportional to the reflections, a string carrying a number of reference disks vertically oriented below the housing for producing a series of reflected acoustic signals from each reference disk, and a processor connected to the ultrasonic transducer for activating the transducer and for analyzing the reflected pulses for calibrating the apparatus for environmental changes in the atmosphere above the stored fluid and for determining the level of the stored fluid in the tank. The method of the present invention includes the steps of receiving reflected pulses from each reference disk only during certain window time intervals and to calibrate the system by adjusting for environmental conditions between the transducer and the fluid level.
