The Siemens 7ME3960-0MR00 is the RTD mounting hardware for the SITRANS FS220 ultrasonic flowmeter family — the bracket and clamp assembly that secures the temperature probe to the pipe. It covers pipe diameters from 152 to 610 mm (6 to 24 inch). Legacy part number 992EMTN-3 cross-references on the nameplate. This is a dedicated-system part, not a universal adapter. It mates specifically to the SITRANS FS220 flowmeter's RTD port; the pipe range is the only fit variable. If your line is 8-inch schedule 40, this bracket wraps it. If you're on a 3-inch line, this won't cinch down.
Group code R3P3 and product group 4727 are the internal Siemens classification for this accessory line. Useful if your procurement system filters by these codes for BOM matching.
