Tom Kegel

Principal Engineer & Flow Measurement Instructor

Tom Kegel
Tom joined CEESI in 1991. He has over thirty years of experience in flow measurement research, product development, calibration, testing, training and consulting. His current responsibilities at CEESI include new facility development, special test programs and engineering support of measurement processes. Tom has developed a broad understanding of measurement uncertainty that is valuable to CEESI clients as well as forming a solid foundation for the traceability of calibration services. He continues to contribute to expanding CEESI business opportunities in technical training and consulting. He has presented papers at numerous CEESI Ultrasonic Meter User's Workshops; he has presented papers at every International Symposium on Fluid Flow Measurement since 1995.
