The number of channels can be simply summarized into two categories: single channel and multi-channel. The single channel gas meter is suitable for single point measurement, and is used when measuring single dimension parameters such as aperture, cylindrical diameter and thickness. The multi-channel air momentum meter is suitable for single multi-point measurement. Because of the characteristics of multi-channel single multi-point measurement, the multi-channel air momentum meter can easily measure the shape and position tolerance such as taper and coaxial degree.Simply put, the size you want to measure has several places to choose several channels.
