本文讨论涡轮流量计在两相流中(空气与水混合)的试验。试验是在两种条件下进行的:即把空气注入系统分别放在远离被试涡轮流量计102英寸和348英寸的地方,中间经过了三个直角弯管。试验结果表明,当空气流量占水流量25％时,对涡轮流量计输出的影响大约是12％。即使空气流量只占水流量5％,对所试的最大流量点,也会引起6％的偏差。本试验也发现,空气注入系统位置变更,对流量计输出没有什么影响。本试验是在美国Worcester技术学院完成的。 This article discusses the testing of turbine flowmeters in two-phase flow (air-water mixing). The test was performed under two conditions: the air injection system was placed at a distance of 102 inches and 348 inches, respectively, from the test turbine flowmeter, passing through three right-angle elbows. Test results show that when the air flow accounts for 25% of the water flow, the effect on the turbine flowmeter output is about 12%. Even if the air flow only accounts for 5% of the water flow, a 6% deviation will also result for the maximum flow point tested. The test also found that the air injection system position changes, the flow meter output has no effect. This test was done at Worcester Technical College in the United States.
