Flow Meters for Liquids and Gases



Flow Meters Applications

Ethanol Plants

Ethanol Plants America's top automobile manufacturers approve, and even recommend, fuel enriched with up to 10% ethanol and hybrids designed to run on E85 (85% ethanol and 15% gasoline) which is the cleanest burning renewable fuel today. RCM Industries is proud to be a part of the effort to clean up the environment in providing flow measurement products in the production of ethanol. RCM flow meters monitor seal water, ethanol, water / alcohol mixture and fusel oil keeping production processes on line and on time.

Radars, TV & Satellite Systems

RCM flow meters monitor critical flow measurements of 50/50 ethylene glycol or propylene glycol and distilled water for liquid cooled TV transmitters. Our flow meters are able be fitted with reed switches to protect equipment against low and high flow conditions. This technique ensures a direct correlation between the flow rate indicator and the flow switch for ease in configuring a safety interlock or control circuit. These switches are hermetically sealed and epoxy potted for a tamper resistant switch.

Pre-Conditioned Air Handling Units

Our flow meters are also used on water cooled chillers used in the Laser, Industrial, Scientific and Semiconductor industry to control various processes. Chillers provide advanced thermal management solutions in various processess Jetway Air handling units provide cool air flow during pre-flight and loading of aircraft at all major airports dramatically reducing fuel and operating cost.

Beverage Industry

RCM Industries supplies flow meters to several beverage bottling plants used for blending processes, carbo - coolers, carbon dioxide injection equipment, flow -mixers, and beverage prep systems. Typically flow meters applied to carbo - coolers are 316 stainless steel construction for corrosion resistance. As you can see in the pictures to the right the RCM flow meters plays an important roll in monitoring CO2 flow in the beverage blending process.

Company History


About RCM Industries, Inc.

In 1966 Roy C. Marker was a field engineer for Applied Radiation. On a tour at a 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, 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.
