ZLS was founded in 1991 in response to a need
for a high-quality company that would provide the latest in state-of-the-art
technology for gravity meter instruments. The company was started in
Austin, Texas by three individuals with experience in designing and
manufacturing gravity meters: Dr. Adams, Larry Burris and Herbert Valliant.
Dr. LaCoste suggested that the company be named after his Zero-Length Spring.
The name was fitting and the three began working on their first product, an
upgrade for LaCoste & Romberg (L&R) S-meters. Since its start, ZLS has
continued to develop its products and services and now offers its own line of
gravity meter products which include a land gravity meter (Burris
Gravity Meter™) and a Marine / Airborne gravity meter (ZLS Dynamic Gravity Meter™).
To continue servicing the gravity meter community ZLS also offers a range of
state-of-the-art technology products for L&R G, D, ET, and S-meters.
Principles of ZLS
Over a
Century of Combined Experience with Gravity Meter Design and Production
President
James R. Adams, BBA, MBA, Ph.D., spearheads the business
activities and production of ZLS in addition to design, research, and
development responsibilities. Dr. Adams has had 25 years experience in gravity meter production, construction,
assembly, R&D, and testing. His previous affiliation was as Vice-President in
charge of Production at LaCoste & Romberg Gravity Meters, Inc.
Vice President
Larry J. Burris has 47 years experience in the
mechanical design of gravity meters and associated instruments. His
primary responsibility at ZLS is to design, research, and develop gravity and
tilt meters. Mr. Burris founded INSTECH, which specialized in the design
and manufacture of precision levels and tilt meters. His previous
occupation was as head of Research and Development at LaCoste & Romberg
where he was responsible for the design and development of gravity meter sensors
including the straight-line air/sea meter and borehole gravity meter.
Vice President
Herbert D. Valliant, BSc, MSc has 46 years
experience in all facets of gravimetry and systems engineering. Mr.
Valliant designs, researches, and develops electronics and controller systems
for L&R and ZLS gravity meters. Formerly, he worked for the Geological
Survey of Canada where he authored over 80 scientific papers. One of his
more recent publications is a chapter on marine gravity instrumentation in the Handbook
of Geophysical Exploration at Sea (CRC Press, 1992). His experience
includes marine, land, and airborne field operations as well as the design and
engineering of gravity instrumentation and systems. Most recently he was
employed as Senior Scientist at LaCoste
& Romberg Gravity Meters, Inc.
