Brooks Instrument Sho-Rate 1250 Variable Area Flowmeter
About this part
1250AR6101MRSVV is a configured Brooks Instrument Sho-Rate 1250 low-flow glass tube variable area flowmeter. The useful decoded element is the R6101 tube/float scale context: Brooks 1250/1255 documentation lists R6101 as a millimeter-scale table entry with 23,640 CCM air and 570 CCM water values, and product/listing evidence repeats the 0-23,640 CCM air range for this exact part number. Sonisys preserves those observed configured-unit values together with stored auction prices and deduplicated images
Configurations vary. Verify the exact unit before choosing a replacement.
