From Sierra’s beginning over 40 years ago, founder Dr. John G. Olin was driven by the vision of supplying industrial customers with the world’s most accurate mass flow meter. And, he knew it was a ‘sensor’ game.
With a background – and Ph.D. – in mechanical engineering and specialised in fluid mechanics and heat transfer, Olin was a driven innovator and founded Sierra Instruments Inc. in 1973 with the purpose of offering industrial grade thermal mass flow meters to solve industry’s need for rugged, reliable flow meters based on the thermal principle.
The development of an industrialised metal-sheathed sensor in the early 1980s was Sierra’s first big step, but was only the beginning for Dr. Olin, who saw ‘thermal mass flow’ as his life’s work. Many successful innovations followed, including a major breakthrough in 1999 with the introduction of Sierra’s patented no-drift DrySense™ mass velocity sensor. With this development, Sierra engineers recognised they were on the cusp of realising Dr. Olin’s vision.
