Application of a Pulsed Sonic Liquid Level Device to Chemical Processing Tanks

摘要

The ever increasing concern over safeguards and accountability of nuclear material has prompted the need for a more accurate and reliable liquid level measurement device. Although accurate and reliable instruments were currently available, unique situations at the Rocky Flats Plant made most of these devices impractical. Some of the criteria used in the selection of a liquid level measurement device for use in the chemical processing areas of the plant included: (a) exceptional accuracy and reliability, (b) nonintrusiveness or nonpenetration of the process tank, (c) ease of installation, (d) standard interface electronics, (e) a digital display, and (f) moderate cost. This paper details the selection, operation, and production use of the Bartex Aquatrak Model LG-1101 Liquid Level Indicator 1. This was the only system tested which met or exceeded all of the requirements that were set. 2 references, 3 figures. (ERA citation 10:008427)
