The structure and performance of a batch of intelligent fast reactor sodium gauges newly introduced are introduced, and corresponding graduation characteristics equations of medium temperature parameters are given. These intelligent sodium gauges have good linearity, Temperature effect online compensation function, so that it can get accurate sodium flow, pressure, level measurement data. Moreover, these smart sodium meters feature self-test, brownout protection, full scale settings, alarm limits (double upper and double lower) settings, broken alarm, isolated 0 ~ 10V DC analog output and CENTRONICS standard digital output and alarm Relay contact output. These superior features, based on a single-chip microcomputer, make these smart sodium gauges particularly suitable for instrumentation, control and protection systems for sodium-cooled fast reactors. The basic error of intelligent sodium flowmeter, intelligent submersible sodium flowmeter, intelligent sodium pressure gauge and intelligent sodium liquid level gauge are respectively ± 2%, ± 2.3%, ± 0.3% and ± 1.9% of range.
