The 7ME3960-0MR02 is the RTD mounting hardware kit for a dedicated SITRANS FS220 ultrasonic flowmeter system. It covers pipe diameters from 31.8 to 203.2 mm (1.25 to 8 in). The legacy part number is 992EMTN-2, so if you are replacing an older install, that cross-reference confirms the fit.
Sourcing reality — active but built to order
Lifecycle status is active per Siemens, so this is not an obsolete or NRND line. However, the product class is C: manufactured or produced to order, which means it is not a stocked shelf item. Expect it to be built against a purchase order. Lead time will depend on the manufacturing queue, not a warehouse bin.
Compliance note — not RoHS
This part is not RoHS-compliant. If your project or end customer requires RoHS conformity for the installation, factor that in before specifying. REACH Article 33 candidate-list information is available on request.
