Vibratory density meter is a kind of instrument specially used for testing powder vibratory density,which is widely used in pharmaceutical,new energy,powder processing and other industries.The measurement methods and requirements are introduced in a number of international and domestic standards,and the requirements for pa-rameter calibration are put forward in the quality management system of relevant enterprises.Its main parameters in-clude vibration frequency and displacement,need to be calibrated,because there is no reliable method and equip-ment in China,so the problem of on-site calibration needs to be solved.In this paper,the difficulties in calibra-tion and calibration methods are discussed,analyzed and studied.
