embedded strain sensor which is impervious to most fluid types it is powered from a voltage source usually five volts and ground differential and provides an output which is generally linear to pressure the output may be a voltage level or current level for example a level of 0 5 to 4 5 volts with values therein proportional to force on the sensor from empty to 100 of calibrated level the calibrated level does not need to use the full scale of the device for instance an empty condition might be 0 5 volts and a full condition might be 1 0 volts this would allow an improper filling to show a value slightly greater than 1 0 volts the system may use a single or a multiplicity of fluid level sensors per tank 12 microprocessor the microprocessor accepts the condition from the fluid sensor and interprets via a software implementation similar to the flowchart the current level of the fluid within the tank 14 display device the microprocessor commands the display device to show the current level of fluid within the tank or enclosure for instance a fluid level of 50 volume would produce an indication of 50 via an led display or an lcd display or an analog needle style display or any type of display or indicator which allows the operator to see or hear the fluid level 16 alarm the microprocessor commands an alarm which shows a mis fueled condition or other alarm condition in the simplest example this would include an incorrect fluid type which is detected via an algorithmic determination that too many pounds of fluid are in the tank given a known fluid type and given a known tank volume in other examples the alarm could be triggered at critical.
