About Our Company

FLUTe was founded in 1996 by Carl Keller, principal scientist, to apply the unique attributes of inverting/everting flexible liners to underground measurements and other uses.  The quality of construction, performance, and cost effectiveness of our flexible liner systems are why our customers keep returning.
Carl Keller is the recipient of the 1994 R&D 100 Award for his first flexible liner patent. The FLUTe designs have gained recognition with the National Ground Water Association Technology Award in 2008. FLUTe systems have continually evolved and are now used in 12 countries by large corporations, regulatory agencies, and research institutions.  FLUTe’s unique methods are covered by 22 domestic plus 13 foreign patents with others pending.

FLUTe’s main plant and offices are in Velarde, NM with other facilities in Albuquerque, NM and Warminster, PA.

FLUTe methods for high resolution underground measurements of many kinds have gained acceptance as superior, or complementary, to traditional methods.
