Background. The research object is the mass air consumption meters for electronic systems of car engine control. The research subject is a microprocessor instantaneous mass air consumption meter that features the method of ultrasound measurement. The aim of the work is to expand functional capacities and to improve accuracy of the instantaneous mass air consumption meter by using the method of ultrasound waves’ phase shift measurement that spread up and down the air flow.
Materials and methods. The authors researched metrological characteristics of the developed measurement device with realization of a full-size sensing element sample and schematic solution on the basis of the NI ELVIS virtual laboratory complex.
Results. The authors developed an ultrasound sensor’s construction, structural and principal schemes of an electronic microprocessor unit of data processing and a functioning algorithm for the mass air consumption meter in normal and extreme modes. The device can be used as a part of electronic systems of gasoline internalcombustion engine control.
Conclusions. The microprocessor instantaneous mass air consumption meter provides an opportunity to measure mass air consumption in both directions with improved accuracy using the results of instantaneous temperature and air density measurements.

Key words

electronic control unit, air consumption meter, ultrasonic transducer, phase shift of ultrasonic wave, metrological characteristics.
