Measurement of liquid level and density and dip-tube sensors was evaluated by analysis and experiment. A model was developed to predict the characteristic error caused by the purge-gas bubble (dip-tube bias). Experimental results are presented to support these predictions and are also compared with data reported in the literature. It was shown that properly designed and calibrated dip tubes do not make significant contributions to the error in dip-tube level and density-measurement systems.
