ABSTRACT:
A flow-through sampling device is provided for obtaining clear filtrate samples from a pipeline containing a slurry of phosphoric acid and calcium sulphate. The sampling device comprises a sample chamber having inlet and outlet pipes connected to the high pressure and low pressure sides of the pipeline, respectively, the sample chamber having a filter attached to its side portion for removing solids from the slurry prior to obtaining a fluid sample. The sampling device can be equipped with an automatic analyzer for continuously monitoring the composition of the flow stream.
