Abstract
Способ калибровки датчика потока, включающий испытание калибруемого датчика потока, которое состоит в пропускании фиксированного объема воздуха через калибруемый датчик потока, регистрации и накоплении значений показаний калибруемого датчика потока, математическую обработку зарегистрированных значений и определение калибровочной характеристики, отличающийся тем, что испытания выполняют многократно с различными скоростями пропускания воздуха, при проведении испытаний распределяют регистрируемые значения показаний калибруемого датчика потока по выбранным интервалам, на которые разбивают весь рабочий диапазон значений потоков, измеряемых датчиком, испытания выполняют до получения равномерного заполнения интервалов по количеству зарегистрированных значений показаний датчика, а в качестве калибровочной характеристики используют зависимость реальных значений потока от зарегистрированных значений показаний датчика, которую строят с использованием кусочно-линейной аппроксимации в выбранных интервалах рабочего диапазона значений потоков, измеряемых датчиком. A method of calibrating a flow sensor, including testing a calibrated flow sensor, which consists in passing a fixed volume of air through a calibrated flow sensor, registering and accumulating the values of the calibrated flow sensor readings, mathematical processing of the recorded values and determining the calibration characteristic, characterized in that the tests are performed repeatedly with different air transmission rates, during testing, the recorded values of the calibrated readings are distributed the flow sensor at selected intervals into which the entire operating range of flow values measured by the sensor is divided, the tests are performed until the intervals are uniformly filled by the number of recorded values of the sensor readings, and the dependence of real flow values on the recorded values of the sensor readings, which is built, is used as a calibration characteristic using piecewise linear approximation in selected intervals of the working range of the values of the flows measured by the sensor m
