在制冷和空气调节中,准确地测量空气的流速,是一个重要问题,为此,新研制了一种气动风速仪(图1),并已用于实际。其工作原理图式是基于差动-指零测量方法。这个仪器可以在较大范围内测量含尘气体(空气)的流速。
In cooling and air conditioning, the accurate measurement of the air flow rate is an important issue. For this reason, a pneumatic anemometer has been newly developed (Figure 1) and has been used in practice. The schematic of its operating principle is based on the differential-finger-zero measurement method. This instrument can measure the flow rate of dust-laden gas (air) in a wide range.
