FIELD: measurement technology. SUBSTANCE: proposed flow meter includes primary transducer and electronic unit (digital frequency meter) consisting of pulse shaper connected to primary measuring transducer, reference frequency generator whose output is connected with control unit connected in its turn with one of inputs of electronic switch, correction unit, pulse counter and digital indication unit. Input of correction unit is connected to temperature sensor rigidly secured in housing of primary measuring transducer and output is connected to reference frequency generator. EFFECT: enhanced accuracy of measurement due to avoidance of error caused by change in fuel temperature. 1 dwg
