1020NN0B2AA5F9D00001 is a configured Brooks Instrument GT1000 Series glass-tube variable-area flowmeter identifier observed in Sonisys auction records and surplus listings. Brooks GT1000 documentation decodes the configured code as a 1020N horizontal-inlet / horizontal-outlet meter with size-12 tube, no alarm option, 316 stainless steel end fittings, Viton O-rings, NPT-F threaded connections, 1-1/2 inch connection size, right-side direct-reading gas scale, no left-side scale, 2% full-scale accuracy with international calibration certificate option, no needle valve, no panel mounting, no process certificate, no additional certificate requirement, and standard Brooks identification. The observed 800-8000 SCFH range is retained as listing and image context rather than an official model-wide range; process gas, scale conditions, pressure rating, tube/float condition, and replacement fit should be verified from the physical meter label and Brooks documentation
Configurations vary. Verify the exact unit before choosing a replacement.
Stored auction and surplus listing evidence identifies this configured meter with 800-8000 SCFH wording; verify the physical scale, gas, pressure, temperature, and calibration basis before using the range as a process limit
Flowmeter family
Measuring principle
GT1000 documentation identifies the family as glass-tube variable-area flowmeters
Temperature
Family temperature context
GT1000 documentation lists 33 to 125 F / 1 to 52 C ambient limits and 33 to 250 F / 1 to 121 C operating-fluid limits for the meter
Pressure
Size-12 pressure context
GT1000 documentation lists size-12 maximum operating pressure of 100 psig / 6.9 bar for threaded and flanged connections at fluid temperature up to 250 F / 121 C; process suitability depends on the actual unit and service conditions
Serviceability
Tube service
GT1000 documentation describes O-ring construction that allows glass tube removal for cleaning or maintenance without removing the meter body from process piping
Configuration
Configured-unit rule
Verify the physical tube label, scale, fluid, process conditions, pressure rating, flow direction, tube and float condition, seal compatibility, and installed piping before using this meter as a replacement
