A portable microprocessor based fuel flow and distance measurement instrument has been developed which can perform distance, speed, and acceleration measurements using a standard fifth wheel and simultaneously measure fuel volume, calculate mass flow and totalize the fuel consumption using a positive displacement flowmeter. Efficiency ratios such as miles per gallon and liters per 100 kilometers are also provided. Included are a 6-digit display for time, distance, volume, and flow totalization and a 4-digit display for speed, acceleration, mass flow, volume flow, fuel temperature, and efficiency; plus two selectable analog outputs. This paper describes the design objectives, operation, and additional-special features of the instrument.
