Calibration of Vibrating Density Meter Using Liquid Density Reference Material
According to JJG 1058-2010"Laboratory Oscillation-type Liquid Density Meters",a method of cali-brating vibratory liquid densitometer(densitometer)with liquid density standard(densitometer)was proposed,and the precision level densitometer was compared with SHANGHAI Institute of Metrology(SIMT).In the range of(650~2000)kg/m?,three density markers with stable physical and chemical properties were selected as measure-ment markers,the density meter was calibrated,and the measurement characteristics of the density markers were an-alyzed.The results show that the maximum value of | En | is 0.3,and the comparison results are satisfactory,which provides a practical and feasible method for the calibration of such instruments,and is helpful to the research and development of high-precision density measuring instruments in our country.
