Sažetak
The paper presents a microprocessor controlled gas-flowmeter comprising the autocalibration and the compensation of nonlinearities of the voltage to frequency converters. Depending upon required precision the calibration in two or more points is performed and generally nonlinear characteristic of the voltage to frequency converter can be piecewise linearly approximated. Owing to autocalibration a high accuracy of the flow calculation can be achieved even with low performance converters. No external adjustment of the converters are necessary.
