Roy Dunlap, founder of SOR Inc., a manufacturer of pressure, level, temperature, and flow measurement products, passed away April 25, 2013.

Dunlap leveraged the static-o-ring (SOR) technology to invent a highly accurate mechanical pressure switch that helped prevent the overfilling of oil tanks. This simple but innovative design resulted in a switch of flawless accuracy that would change the oil & gas and power generation industries forever. The static-o-ring pressure switch was developed in 1956 and its success will continue to impact the lives of Dunlap’s employees for years to come.

Dunlap initially realized his dream of having his own commercial machine shop shortly after he left the Navy following World War II. Starting small with just $2000 and one employee, he opened the doors in 1946. That machine shop was later named one of the top 10 machine shops in America, by American Machinist magazine.

Dunlap remained involved in the business and on the Board of Directors until his passing. His daughter, Linda Dunlap, assumed the role of chairman of the board in 2010.

“He had a rich, full life and would have turned 91 in July,” said Linda Dunlap. “My father touched the lives of many people and will be greatly missed, but his legacy continues on through the continued growth of the company that he loved so much.”

Since 1956, SOR Inc. has offered a comprehensive line of level, pressure, temperature, and flow instrumentation for a wide variety of industries and applications. SOR Inc. has a registered quality system to ISO 9001:2008. World headquarters and manufacturing facilities are located in Lenexa, KS, with sales offices in the United Kingdom and China. SOR Inc. also supports its markets worldwide with more than 100 representatives.
