Experimental study on a method of measuring point distribution of pressure measuring pipe in ventilation ducts

The pressure measuring pipe is a common probe device for ventilation duct pressure measurement, and its structure is directly related to the accuracy of pipeline pressure measurement. In this paper, a form of pressure measuring pipe is proposed, and its theoretical analysis and multi-condition experimental verification is carried out. The results show that compared with the commonly used pressure measuring pipe layout method, this form of pressure measuring pipe is not only convenient to measure, but also more accurate in measurement results.
