In 1966 Roy Clifford Marker (RCM) was a field engineer for Applied Radiation. On a tour at the NASA facility in Texas, he was briefly shown a large panel of non-functioning flow gauges of various types and sizes. His tour guide pointed out how a majority of gauges were either inaccurate, non-functioning or in the process of repair. His guide then said that a basic, sturdy, dependable flow gauge would be a major benefit to the industry. After this trip Roy challenged himself to come up with a simple flow meter which was rugged and reliable, and was easy to apply and install and would give years of service. After developing the Flo-Gage, he launched RCM Industries in 1972 to provide this flow meter to the market. After Roy's untimely death, his wife Lenore Marker managed the business until her retirement in 1987. Our staff today includes many of Roy's original staff from the 1970's.
Roy Marker obtained his degree in mechanical engineering and business from the University of California Berkeley. With his vision to develop a flow meters that is rugged, reliable and easy to apply much of his time was spent in the garage researching, designing, testing an idea to develop a differential pressure flow meter using the Bernoulli's equation to measure flow of fluid's and gases. Roy wanted to design a unique flow meter one that would covered a variety of applications for industrial process control.
Roy spent countless hours testing each individual component from the gear movement, bearings, bellows, seals etc. under extreme conditions such as high pressure, high temperature for process water, various gases, ammonia service, saturated steam service, and oil. The materials of construction offered are Bronze, Stainless Steel and Monel.
The RCM Flo-Gage is a direct reading flow meter that measures flow based on a pressure differential across a calibrated nozzle when the flow increases, more pressure drop is created. Impulse piping routes the upstream and downstream pressures of the flow meter to mechanical bellows, gear movement and pointer to provide indication on a large easy to read dial calibrated in engineering units.
