Wireless simultaneous measurement system for liquid level and density using dynamic bubbler technique: Application to KNO3 molten salts

다국어 초록 (Multilingual Abstract)

We have developed a liquid level measurement system using the dynamic bubbler technique. Based onour previous methodology, herein, we established afield-applicable wireless measurement system tosimultaneously monitor the liquid level and density of corrosive molten salts at high temperatures. Theaccuracy and precision of the present technique were suitable for applications in harshfield processes.
Regardless of the base pressure under the present experimental conditions, percentage differencescompared with reliable reference values in the literature were less than 10% in the temperature range773–1123 K using KNO3 as a molten salt. Our dynamic bubbler technique produces an average percentagedifference ca. 5–8% with a standard deviation of less than ca. 0.04 g cm 3 between measured andliterature density values in all experiments, whereas the standard deviations in all liquid levelmeasurements were less than 0.3 mm (0.07% relative standard deviation). The present technique is anexcellent alternative to many conventional liquid level and density measurement techniques used underextreme environmental conditions characteristic of common industrial processes.
