威力巴流量计在煤矿管道瓦斯流量计量中的应用
Application of Verabar flowmeter in pipeline gas flow metering of coal mine
摘要
Abstract
In view of problems of complex installation,low measurement accuracy and large permanent pressure loss of pipeline gas flowmeter of coal mine such as V-cone flowmeter,orifice flowmeter and ultrasonic flowmeter,an application of Verabar flowmeter based on differential pressure measuring principle in the pipeline gas flowmeter of coal mine was introduced.Measuring principle and performance features of the Verabar flowmeter were given,a viewpoint was pointed out that the Verabar flowmeter has the best performance of anti-blocking compared with the other averaging velocity tube flowmeters.The result of experimental and field tests show that the Verabar flowmeter has characteristics of accurate measuring,simple structure,low pressure loss and can be suitable for detection of the pipeline gas flow of coal mine.关键词
