		Gas Mass Flow Meters FCI designs, manufactures and sells a broad line of air / gas mass flow meters utilizing thermal dispersion and measurement technology. Thermal dispersion technology utilizes the relationship between flow rate and cooling effect for direct measurement of mass flow. With no moving parts and minimal invasiveness, thermal dispersion is ideal and widely applied in air and gas applications, and provides a highly repeatable and accurate measurement.
FCI transmitters and electronics feature advanced microprocessor-based circuitry and rugged construction. These include features such as simple configuration of the signal outputs, display or alarm setting in the field, or analog and digital outputs, easy servicing and maintenance, and long-life in even the harshest of plant installations. FCI has designed and developed several mass flow meter product families and more than 20 models to meet a broad range of performance and environmental application requirements. Each FCI flow meter group can be distinctly identified by the following listed general instrument characteristics:
