Celerity UFC-1660-20000SCCM-HCL Mass Flow Controller

Celerity UFC-1660 Mass Flow Controller is a precision gas-delivery device designed to regulate hydrogen chloride (HCl) flow in analytical and process environments. The UFC-1660 model supports a maximum flow of 20,000 SCCM (20 SLPM) and is identified with ASM part number 54-123389A11, aligning with Celerity’s UFC-1660 family of standard-flow controllers. This variant is specified for HCl gas, enabling controllable, repeatable metering in gas-handling manifolds. In operation, the unit converts an electrical control signal into a proportional valve opening to modulate HCl flow, providing stable setpoints and repeatable delivery in laboratory and industrial gas systems. The UFC-1660 designation sits within the broader 1660-series portfolio, whose standard-flow configurations span roughly from 10 SCCM to 30 SLPM, so a 20,000 SCCM maximum falls squarely within the family’s documented capabilities. The combination of gas compatibility (HCl) and a 20,000 SCCM maximum makes this model suitable for applications requiring higher-throughput, reliable delivery of chlorine-containing gas in controlled environments.
