核反应堆堆芯冷却剂流量测量用涡轮流量计的研制及应用

摘要

In order to meet the needs for measuring the coolant water flow rate in-core of a nuclear heating reactor,two types of turbine flow meter with low rotation speed have been developed in our institute. Both calibration tests and applications show that the turbine flow meter with low rotation speed has many advantages, such as good accuracy and repeatability, the root-mean-square of a relative error of 1.0%,long working life,less resistance,a wide range of linearity and low pressure drop across the meter,etc.%为适应核反应堆堆芯冷却剂流量测量的需要，开发研制了新型低速涡轮流量变送器，按流量信号输出不同，分别为磁感应模拟信号输出和数字开关量输出低速涡轮流量变送器。实际标定和应用表明，低速涡轮流量变送器的精度和重复性是好的，相对误差的均方根为1.0%，使用寿命长，阻力小，线性范围宽。
