| Abstract: | 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 |
