涡轮流量计在许多工业部门中得到了广泛的应用,在航空和宇航方面,其应用价值就更大了。我国研制这类流量计已有二十多年的历史,生产出了各种规格的产品提供使用。然而,国产流量计的叶片一直是螺旋形的。去年,我国传感器考察团参观了英国的几家流量计公司,发现他们不但生产螺旋形叶片,而且也普遍采用平板叶片。 Turbine flow meters have found wide application in many industrial sectors and are of even greater value in aerospace and aerospace applications. The development of such flow meters in China has been more than twenty years old and produced a variety of products for use. However, the leaves of domestically made flow meters are always helical. Last year, our sensor delegation visited several British flowmeter companies and found that they not only produce spiral blades, but also commonly used flat blades.
