从弯管流量计发展的历史看,弯径比是影响弯管流量系数最大、最关键的参数,又是弯管传感器理论模型中唯一的几何特征参量,因此它对测量准确度有直接影响,同时也是在批量生产中要严格控制的参数。由于弯 From the history of the development of elbow flowmeter, the bending radius ratio is the most critical parameter that affects the elbow flow coefficient, and is the only geometric characteristic parameter in the theoretical model of elbow sensor. Therefore, it has a direct impact on the measurement accuracy, It is also a parameter that must be strictly controlled in mass production. Due to the bend
