摘要:【中文】本发明提供了一种风量测量装置,涉及测量技术领域,解决了现有技术中存在的L型和S型风量测量装置采用单点取压,测量结果存在较大偏差的技术问题。该风量测量装置包括全压管和静压管;所述全压管、静压管相互平行,并固定在进风管道或箱体内;所述全压管上至少设置有两个全压测孔;所述静压管上至少设置有两个静压测孔;所述全压测孔、静压测孔分别正对气流和背对气流。本发明通过多点取压然后计算平均值,就能够得到整个截面的平均压力,对风速和风量的测量就更加精准。同时,由于全压管、静压管可进行独立设计,直接使用标准管材即可加工制造,不需要特殊模具,也较现有风量测量装置的标准设计具有更大的灵活性。 【EN】The invention provides an air volume measuring device, relates to the technical field of measurement, and solves the technical problems that an L-shaped air volume measuring device and an S-shaped air volume measuring device in the prior art adopt single-point pressure measurement, and the measurement results have large deviation. The air quantity measuring device comprises a total pressure pipe and a static pressure pipe; the total pressure pipe and the static pressure pipe are parallel to each other and are fixed in the air inlet pipeline or the box body; the full-pressure pipe is provided with at least two full-pressure measuring holes; the static pressure pipe is provided with at least two static pressure measuring holes; the full pressure measuring hole and the static pressure measuring hole are respectively opposite to the air flow and opposite to the air flow. According to the invention, the average pressure of the whole section can be obtained by multipoint pressure measurement and then average value calculation, so that the measurement of the wind speed and the wind volume is more accurate. Meanwhile, the total pressure pipe and the static pressure pipe can be independently designed, and can be processed and manufactured by directly using a standard pipe without a special die, and the wind volume measuring device has higher flexibility than the standard design of the existing wind volume measuring device.
