变截面小流量计(转子流量计)的模拟方法已得到发展和试验。结果表明:用一种气体对流量计的标定可以预测另一种气体对流量计的标定,其不确定度一般不超过5％。
Variable cross-section of small flowmeter (rotor flowmeter) simulation methods have been developed and tested. The results show that using one gas to calibrate the flowmeter can predict the calibration of the other gas flowmeter, the uncertainty is generally not more than 5%.
