This no-display device uses a thermal mass flow sensing element with digital signal processing to provide stable, repeatable flow regulation suitable for analytical instruments, semiconductor tooling, and plasma processing where Argon delivery is critical. It features 3\/8\" compression fittings for straightforward gas-line integration and an RS485 interface for reliable digital communication, with power supplied by +\/-15 VDC. Designed for standard metering conditions, it assumes 14.7 psia and 21.1°C (70°F) as reference, aligning with common lab and process environments. The DFC46S series is part of Aalborg’s programmable digital mass flow controller family, offering configurable flow profiles to match varied process recipes while maintaining tight control over gas flow. This model’s combination of Argon-specific 0–100 L\/min range, stainless-steel construction, and clean-room‑friendly seals make it a suitable choice for tight-tolerance gas delivery in research and manufacturing setups where precision and reliability matter.\u003c\/div\u003e","brand":"AALBORG","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51656683979054,"sku":null,"price":1740.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_841c2672-8539-47ce-8be4-d9f4e2229983.jpg?v=1769462697","url":"https:\/\/plgautomation.com\/products\/aalborg-instruments-and-controls-dfc46-thermal-mass-flow-controller","provider":"PLG Automation ","version":"1.0","type":"link"}
