Aimed at the problem of domestic calibration difficulties of liquid level sensor for spacecraft,a capacitive liquid level calibration device is implemented and designed suitably. The measurement uncertainty of this device was assessed,and a kind of trace-ability chain of the capacitive liquid level sensor for spacecraft was established. The calculating results show that the measurement un-certainty of the device is approximately equal to 0.291 mm,which meets the calibration requirements.
