The 7ME3960-3MC00 is the mounting hardware kit for a portable Universal transducer size C, belonging to the SITRANS FS220 ultrasonic flowmeter family. It carries the legacy part number 1012FP-PC and is classified as Product class C, meaning it is manufactured or produced to order and cannot be reused, re-utilized, or returned against credit. This is a field-service item for the flowmeter system — the bracket, clamp, or fixture that holds the transducer against the pipe wall during portable flow surveys. If you are rebuilding a SITRANS FS220 kit or replacing a lost or damaged mounting assembly, this is the factory-specified part.
Because this is a Product class C item, it is built to order — not a stocked shelf part. Expect a lead time tied to the manufacturing schedule rather than immediate shipment. Plan your BOM freeze accordingly; this is not a part you pull from a bin for a same-day line fix.
The Group Code is R3P3 and the Product Group is 4727 — these are Siemens internal classification codes used for catalog navigation and compatibility filtering. If you are cross-referencing against a legacy SITRANS parts list, match these codes to confirm the correct mounting hardware variant.
