DELTA M Corporation was established in 1983 in Oak Ridge, Tennessee as one of the first Department of Energy (DOE) technology transfers from the Oak Ridge National Laboratory (ORNL). Since then, DELTA M has established a strong reputation and loyal user base based on our patented thermal technologies. In nearly any level, flow or temperature measurement our customers come to us because we deliver solutions to the process challenges they face every day. DELTA M Corporation continues to design, manufacture, and market unique fluid flow, level and temperature measurement using proprietary and patented thermal-based technologies. Whether it's pump protection, tank truck or rail-car overfill safety, or virtually any time an operator or system designer wants to assure flow or level in a safe and productive range, they rely on our experience and expertise in thermal measurement technology to help them through to solutions, time after time, since 1983.
