 
Process Control Pioneer
In 1915, Ervin G. Bailey, a mechanical engineer
born in Ohio and educated at The Ohio State University, invented the Bailey
boiler meter. He then founded Bailey Meter Company, forerunner of Bailey
Controls, in 1916, to manufacture his invention. The new meters revolutionized
operation of steam boilers and laid the foundation for modern process control
systems used in factories around the world.
The meter monitored both the condition of the steam flow and the airflow in
boilers, giving boiler operators more accurate information on air usage and
steam output. The meter set the direction for future automatic boiler controls,
and helped advance process control systems as we know them today. Bailey also
held several other patents that focused on increasing the efficiency of coal
burners. In 1979, CCI Controls acquired the Bailey line of control valves.
