The unit uses a 1.125-inch footprint and a 9-pin network interface, with a C-Seal for a robust, leak-tight seal. This 8561 variant supports high-purity metal seals and includes RS-485 digital and an optional analog interface for setpoint control and status feedback depending on the connector configuration. The model is specified for a flow rate of 100 SCCM, making it suitable for low-flow applications that require tight regulation. It is part of Celerity’s 8560-series family of mass flow controllers and meters, documented to include high-purity metal-seal options and digital\/analog interfaces. Current listings note that UFC-8561 has been discontinued by the manufacturer, with third-party vendors offering remaining stock or repair services within the 8560 family. For clean-room or analytical instrumentation contexts, the combination of a small form factor and sealed interfaces helps minimize leak risk while enabling reliable gas-delivery control.\u003c\/p\u003e\u003c\/div\u003e","brand":"CELERITY","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51677903094062,"sku":null,"price":219.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_ecea72f5-2230-461b-bd82-66f97546c00d.jpg?v=1769569227","url":"https:\/\/plgautomation.com\/products\/celerity-ufc-8561-10l-ar-mass-flow-controller","provider":"PLG Automation ","version":"1.0","type":"link"}
