Products and Technology
Flow measurement based on Thermal Dispersion technology delivers proven performance and reliability in the harshest environments. When rugged conditions combine with strict process control requirements, FCI's Thermal Dispersion designed sensing elements have established an unmatched record of superior product performance and reliability.
Thermal Dispersion Technology
The typical thermal mass sensing element contains two thermowell-protected Resistance Temperature Detectors (platinum RTDs). When placed in the process stream, one RTD is heated and the other RTD senses the process temperature. The temperature difference between the two RTDs is related to the process flow rate as well as the properties of the process medium. Higher flow rates or denser media cause increased cooling of the heated RTD and a reduction in the RTD temperature difference.
Advantages of Thermal Dispersion
- No moving parts, orifices, bearings or seals to foul or fail
- Accuracy for precision flow measurement, especially in low flow applications
- Repeatability for consistent measurement in complex process environments
- Wide flow range and wide turndowns for a broad range of applications
- Highly reliable and dependable in rugged process environments
- Easy installation with reduced maintenance requirements
Mass Flow Meters
FCI mass flow meters feature Thermal Dispersion technology in which the relationship between flow rate and cooling effect directly relate to mass flow in gas applications and provide a highly repeatable and accurate measurement of gas or air mass flow rates.
The electronics features advanced microprocessor-based circuitry to enable simple reconfiguration of the signal outputs, display or alarm in the field by using a built-in key pad or handheld communicator.
FCI has designed and developed four standard mass flow meter product families 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:
