Fluid Components International (FCI)
Thermal dispersion flow meters and flow / level switches with no moving parts.
Fluid Components International (FCI) is the specialist in thermal dispersion technology. FCI flow meters measure the mass flow of air and gases directly, without temperature or pressure compensation. They have no moving parts to wear or clog.
FCI flow and level switches use the same principle for reliable no-flow, low-flow and level alarms. Typical uses are flare gas, biogas, compressed air, combustion air and pump protection.
FCI is part of DwyerOmega. Ronsor sizes and configures each meter or switch for your gas composition, flow range, line size and installation.
