1250GAR6021MRSVV is a configured Brooks Instrument Sho-Rate 1250G low-flow glass tube variable-area flowmeter. Official Brooks 1250/1255 documentation identifies the family as precision low-flow glass tube meters for liquids and gases, with 65 mm or 150 mm scale lengths and configurable tube, float, valve, scale, connection, end-block, and seal options. Stored Sonisys auction records associate this exact configured code with Air 104 CCM context, which should be treated as observed configured-unit evidence until confirmed against the physical scale and flow curve
Configurations vary. Verify the exact unit before choosing a replacement.
