Response of DWPF thermal flowmeters to composition change: Effect on 02 determination in Salt Process Cell
Thermal flowmeters (more accurately described as hot wire anamometers) have been installed in the Salt Process Cell (SPC) at the Savannah River Site to measure in-cell process flows. However, upon investigating the effect of composition on thermal flow meters, it was concluded that determining a priori correction factors is a very complicated process requiring fairly precise knowledge of the vapor composition and the meter characteristics. It is recommended that DWPF estimate air enleakage using a test procedure similar to one being developed in the Precipitate Hydrolysis Experimental Facility (PHEF) which circumvents the correction problem by in situ calibration, and develop a profile which characterizes air inleakaqe as a function of [Delta]P to be used in conjunction with the inleakage test procedure. The recommended test procedure has some distinct advantages over the simple material balance approach. More detailed information on the characteristics of thermal flow meters the recommended air inleakage test procedure, and the inleakage profile are discussed in this report.
