Description

пульсов посто нной длительности, заполненные импульсами тактового генератора.pulses of constant duration, filled with pulses of the clock generator.

При этом частота тактового генератора /т.г. выбираетс  из соотношени :The frequency of the clock generator / tg is selected from the relationship:

f f

/т.г. -./ tg -.

т/гt / g

где tga - тарировочпа  характеристика вертушки;where tga is the characteristic of the pinwheel;

т - длительность выходных импульсов ждуш,его мультивибратора, абсолютна  величина их определ етс  максимальным числом оборотовt is the duration of the outgoing pulses of its multivibrator, their absolute value is determined by the maximum number of revolutions

п - коэффициент, величина которого зависит от единиц измерени  усредненной скорости потока и от заданной величины погрешности квантовани . Таким образом, показани  регистрируюшего устройства завис т только от усредненной скорости потока и не завис т от конструю цип вертушки и ее тарировочной характеристики . n is a coefficient whose value depends on the units of measurement of the averaged flow rate and on the specified value of the quantization error. Thus, the readings of the registering device depend only on the average flow rate and do not depend on the design of the turntable tsip and its calibration characteristic.
