HIGH-PRECISION CORIOLIS MASS FLOWMETER FOR BULK MATERIAL 2-PHASE FLOWS

For measuring or dosing purposes in gas/solid two-phase flows (non-pre ssurized and pressurized systems) a mass flux measurement device based on the Coriolis principle has been developed. The Coriolis flowmeter developed is applicable for on-line measurements of the mass flux, sho wing a fast response time to load variations and measuring accuracies of +/- 1% of the actual measured value. The Coriolis flowmeter was suc cessfully tested in pilot and industrial plants. Different granular ma terials, such as coal dust, quartz sand, feldspar, plastic granulates and foodstuffs have been measured already. In practice, the Coriolis f lowmeter has shown reliable operation in various applications in proce ss engineering. The integration of the Coriolis flowmeter into advance d control systems for feeding or dosing purposes opens new possibiliti es for on-line control and exact dosing of gas/solid two-phase flows.
