求翻译：在换热站测量蒸汽，热水，无需直管段。由于换热站空间比较小，选择一般流量计要求直管段较长，影响运行精度，用在测量高炉煤气，有自清洁作用，引压管不易堵塞。是什么意思？

Measurement of steam, hot water, heat transfer stations do not need straight pipe. Space is relatively small due to the heat exchange station, general flowmeter requires a long straight pipe affect the running accuracy, used in measuring blast furnace gas, self-cleaning effect, lead pipe is not easy
