前言本文对美国TSI公司生产的1050A恒温热线热膜流速仪在测量流体平均流速时,由于被测量的流体温度与流速仪校准时的流体温度不同而带来的测量误差进行了试验研究,并用曲线回归的方法进行了数据处理,提出了近似的修正公式,可供测量时应用。用热线流速仪测量流体速度时,流体介质温度变化对测量值的影响,前人已做了大量的 Preface In this paper, TSI company produced 1050A hotline hot-film thermal flow meter in the measurement of the average fluid velocity, due to the measured fluid temperature and flow meter calibration fluid temperature measurement error brought about by different experiments and curves Regression method for data processing, proposed an approximate correction formula, which can be used for measurement. With the hotline flowmeter to measure the fluid velocity, the fluid medium temperature changes on the measured value, the predecessor has done a lot of
