Industrial UFC-8561-50CC Mass Flow Controller

UFC-8561 is a Celerity Unit 8560 Series mass flow control device designed for precise, low-volume gas delivery, featuring high‑purity metal seals and RS-485 digital plus analog interfaces, as described in the 8560 Series product configuration. The 8561 variant is documented as part of a family that can be configured with or without a valve, with some configurations categorized as Mass Flow Meter (no valve). The physical footprint is about 1.125 inches, and certain configurations use a 9‑pin network connector, aligning with documented interfaces for the 8560 series. Market listings show UFC-8561 units offered across a range of full-scale flows, including 100 SCCM and 500 SCCM variants in different gas configurations, and consumer listings reference a 50 SCCM variant, consistent with the model designation UFC-8561-50CC. This combination of metal-seal construction, high-purity design, and versatile signaling enables precise gas flow control in applications such as analytical instrumentation, calibration gas delivery, and semiconductor process tooling where tight flow regulation is essential.
