Abstract: In the U-Tube manometer, a capacitive level sensor is used to measure the level of the mercury in terms of capacitance values. The abnormal data obtained from the system may cause noises and ...

The normal mass calibration range is from 1 mg to 64 kg. Uncertainties of measurement range from 40 parts in 10 9 at 1 kg to 2 parts in 10 7 at 60 kg. Calibration at routine higher uncertainties ...
