Brooks Instrument Model 1305 Glass-Tube Variable-Area Flowmeter with 6221 Alarm
About this part
1305-10C-6221 is an observed Brooks Instrument identifier for a Model 1305 glass-tube variable-area flowmeter equipped with 6221 alarm hardware. Official Brooks Model 1305 literature identifies the 1305 as an O-ring-sealed variable-area flowmeter and documents Model 6221 single/SPDT alarm arrangements for size 8 and size 10 meters. The full legacy identifier is not decoded in the current official manual, so tube, float, scale, calibrated fluid, flow range, pressure rating, electrical configuration, and connection details must be verified from the physical instrument and its calibration records
Configurations vary. Verify the exact unit before choosing a replacement.
