Principals
Winsor (Chip) Letton, Ph.D.
Chip's background in manufacturing and research has led to several specialty areas including: multiphase flow measurement, wet gas flow measurement, ultrasonic flow meters, optical flow meters and digital signal processing.
Jim Hall, Ph.D.
During his more than 35 years of experience with technology companies, Jim has developed wide ranging expertise. He has been involved in the development and utilization of flow measurement instrumentation, ranging from multiphase and wet gas meters, gas and liquid ultrasonic flowmeters, gas chromatographs and flow computers. His experience with measurement and allocation of commingled production has been applied to resolving problems for many clients.
Klaus Zanker
Klaus is widely recognized for his contributions to all areas of flow measurement. He has 40 publications and holds 10 patents. He is the designer of the Zanker Flow Conditioner, an invention that was adopted as an international standard in ISO 5167, 1980. During his career, Klaus has made significant contributions at the following instrumentation companies: Daniel, Schlumberger, Sarasota Instruments, Agar and Kent Instruments.
Eric Kelner, P.E.
Eric is a former measurement engineer at Questar Pipeline, and a former manager of the Metering Research Facility at Southwest Research Institute, a world-class flow meter research and calibration facility. His real world operating company experience combine with his experience in applied research to provide a detail-oriented, but realistic view of flow measurement. With expertise in single and multiphase flow measurement, as well as fluid properties and oil and gas quality determination, Eric provides a broad flow measurement knowledge base.
Eric Toskey
Eric joined LHG in 2009 after 20 years with Schlumberger. Eric’s technical specialties include multiphase flow measurement and allocation, well testing and production diagnostics, and technology and product development.
