Automobile calibratable fuel flow measuring system - mechanically determines discharge viscosity valves for electrical conversion into offset pulses per litre, supplied to microprocessor

摘要

The system is used for discharge measuring of fuel and oil of viscosity suitable for engine application. The measuring steps are carried out in the following sequence: The measured valves of the flow volume are detected mechanically and converted electronically into a number of mutually offset double pulse per litre. These pulses are fed into a microprocessor, and simultaneously an offset is added to the microprocessor by a calibrator. The calibrator corrects inaccuracies of the mechanical detection incrementally by using the offset. The corrected measured valves are optically displayed independently of medium discharge. Finally the discharge tap is released for a randomn, or quantity determined delivery of the medium, either by electronic, or electromechanical actuation. Pref. the mechanically determined valves are converted into 200 double pulses per litre, with 90 degree offset.
