This is the dataset for the article titled “Integration of in situ imaging and chord length distribution measurements for estimation of particle size and shape” [Chemical Engineering Science 144 (2016) pp. 87–100]. The dataset was produced with the focused beam reflectance measurement (FBRM) and particle vision and measurement (PVM) sensors both from Mettler Toledo Ltd. Details of measurement procedure are given in [Chemical Engineering Science 144 (2016) pp. 87–100]. More details of the dataset are contained in the PDF file included.
