Evaluation of Anemometers for Use in Coal Mines.
NTIS: PB/211-412 Available for Reference At Bureau Libraries :63 pages
The purpose of the research described in this report was to evaluate existing instrumentation for measuring air velocities in the speed range under 2,000 feet per minute; to evaluate the method for determining total air volume flow from the velocity measurements; to evaluate new techniques that may be applied to measuring air velocities; and to design a prototype instrument that represents the best technique based on the evaluation. Hot film anemometry was the technique selected for the prototype design. Portable and self- contained, the prototype instrument developed is expected to be approvable for use in gassy mines. The three-phase research program involved (1) a literature and information search, (2) laboratory testing, and (3) instrument design.
