The Ronan X96 Density/Mass Flow Measurement System is ideally suited for continuous density measurement of liquids, slurries, and solids contained in a pipe or vessel without making contact with the process material. Since all system components are not wetted to the process such conditions as extreme temperature, high pressure, sterile, corrosive, toxic, or abrasive materials within the pipe do not affect the continuous on-line density measurement.
Each density system consists of a gamma source, detector, and microprocessor. A mass flow system includes an input from a flow meter into the density microprocessor for mass flow calculations. The gamma source, typically mounted external to a pipe, emits energy through the pipe walls collimated in a direction towards a detector, mounted on the opposite side of the pipe. The pipe needs to be kept full of process to hold process volume constant. As the process density increases, the gamma energy reaching the detector will decrease in an inversely proportional relationship to density. The detector measures this changing gamma field and sends a proportional signal to the microprocessor. The X96 microprocessor linearizes, filters, and correlates this signal to a density measurement. A graphic LCD display and outputs are then generated to meet the application requirements.
